How to Plan Luns for Exchange 2007 Virtulization

DSRSAS — Sun, 22 Nov 2009 07:57:02 GMT

I have have a question regarding the planning of the LUNs if I need to virtulizar Exchange MBX, HUB/CAS and Edge server roles. Do make a single LUN and assign it to all ESX host and create a seprate VMDK for each server or do I make a seprate luns for each role and asign to the esx host.

I short I need to know more about the planning of Raid and luns in Storage

vShield VM availability

Iwan Rahabok — Sun, 22 Nov 2009 07:18:32 GMT

Since the vShield VM sits in between the "Protected VMs" and "outside network", what happens if the vShield VM goes down? Do the "Protected VMs" lose access to outside world?

Does a planned maintenance of the vShield VM require downtime of the vShield VM? Planned maintenance here means updating the VM with latest patch or updates.

Thanks in advance

My VMware workstation is very slow!!

pdsouto — Sat, 21 Nov 2009 03:08:20 GMT

I am running a software called SAP ECC 6.0 through the VMware Workstation and the software is installed in my computer, but the performance is very lousy. Even the mouse arrow moves slowly into the VMs window. My notebook is good, I have an intel processor 2.53hz, 4gb RAM, HD (7200 rpm).
Does anybody know how i can speed this softaware up????

My OS is windows 7 (64), and i am running windows server 2003 in the VM.

Thanks

Physical Devices to Guests

saphetiger — Sat, 21 Nov 2009 10:52:39 GMT

I currently run Ubuntu 8.04 with all manor of guests. I am actually interested in switching this around so that the Host OS would be Windows, and my guest would be linux.

My question is as follows:
I see that in VMware Workstation, there is an option to provide the guest with a physical device. Before I go and wipe out my installation I need to know if it is posible to grant access to a non ntfs formatted device in the Windows version? I would really hate for my boss to spend the money and then find out that that all of our important files on our EXT3 partition can't be accessed from a Linux Guest. Due to the volume and type of information stored, it is not feasible or desirable to migrate this over to an NTFS partition, as we want our Linux OS to be hosting it for sure.

Enquiries on Snapshots Management

crescendas — Fri, 20 Nov 2009 01:19:43 GMT

I have multiple snapshots. I assume these will slowdown my system right?

Removing snapshots take a long time and I often receive Operation timed out when removing snapshots. What will be the fastest way to remove multiple snapshots?

Delete the oldest or newest first?
Does suspending or shutting down the VM helps?
Will taking or removing snapshot when VM is booting up or shutting down cause any damage?

I also notice that my first snapshot do not have a "play" icon. What does this mean?

Thanks,

Boon Hong.

downWhenAddrMisMatch - What does it do? How does it relate to NLB?

xmaveric — Wed, 18 Nov 2009 21:32:10 GMT

I'm working with Microsoft Premium support to set up a NLB cluster for 2 Win2003 R2 Enterprise terminal servers. Both machines are VMs. I've got the NLB cluster set up correctly, but I can't ping the cluster IP. Microsoft asked me to move these two machines off of our Layer 3 switch (a Dell 6224) and onto a Layer 2 switch because they said NLB won't work properly on L3.

I did that, but still can't ping the cluster IP from another machine on the same subnet. The next thing they want me to do is set this flag "ethernet0.downWhenAddrMisMatch=TRUE. So my questions for the VMWare community are...

1. What does this setting do and why is it required for NLB to work properly.

2. Is there a way to set it in the GUI or do I need to edit the .VMX file of the VM?

3. Can the setting be changed while the server is running?

4. Is the setting on the VM itself or in the vSwitch?

"Ghost vNIC" VMWare Tools and Virtuasl Hardware V4 to V7 upgrade.

vmproteau — Thu, 19 Nov 2009 22:28:20 GMT

I have recenetly upgraded ESX 3.5.0 (build 163429) to ESX 4.0 (build 175625) I am beginning VMware Tools and then Virtual Hardware upgrades from V4 to V7.

I'm aware that a new vNIC is created and the setting copied over from the old. It also appears it renames the vNIC as a result. All appear normal behavior for the upgrade. However, I see another anamoly that I'm unsure is expected behavior. If not expected what am I doing to cause this:

Every Windows guest I have upgraded VMware Tools on Viirtual Hardware on works fine technically but, when I go into the TCP/IP properties of the new vNIC and then just click "OK" to get out, I get this dialog box (NIC TCP-IP message.jpg attached).

I understand this is a result of the old "Ghost vNIC" and I understand how to remove it to eliminate the message but, if this isn't normal, I'd like to find out what I'm doing to cause this and if it can be avoided. If specific to my environment or upgrade process, I'd like to understand more before proceeding.

Shared writable mmap detection

devzero — Sun, 22 Nov 2009 00:26:30 GMT

Please consider adding detection for special filesystem capabilities and avoid crashing of vmware, especially when support for shared writeable mmap is missing.

i have seen TONS of reports for this on the web (blogs etc) and quite some fuse filesystem mention the needed workaround "usenamedfile=false".

this could be handled automatically and vmware wouldn`t need to crash and the user wouldn`t need to pull his hair out to find the reason for that.

also have a look at:

Installing Virtual Server VM Additions on Windows Server 2008 & Windows Vista

by Vukelic Ranko - January 8, 2009

Virtual Machine Additions are a very important component of Virtual Server 2005 (and Virtual PC 2007). Running VM Additions on a VM is not a must, but you'd better do it as soon as possible, even as the first thing to do right after finishing the installation phase of the OS itself.

LANsurveyor: Map Your Network in Minutes!http://www.petri.co.il/uri/?id=62&host=www.solarwinds.com

Relax while LANsurveyor automatically maps your network.

LANsurveyor automatically discovers your LAN or WAN and produces comprehensive, easy-to-view network diagrams that can be exported into Microsoft Office® Visio®.

You Have Got To Try This! Get the Download Here...

Note: if for some reason, you're using VMware products to virtualize Windows Server 2008 Server Core, you might be interested in reading my Core Installations article.

Virtual Machine Additions adds the following enhancements to a guest operating system:

Improved mouse cursor tracking and control
Greatly improved overall performance
Virtual machine heartbeat generator
Optional time synchronization with the clock of the physical computer

You can use several methods to install the VM Additions:

Through the Virtual Server administrative website
Through VMRC Plus
Unattended installation
Through scripting

Additionally, if you've got Microsoft System Center Virtual Machine Manager (SCVMM) installed, you can also:

Install the VM Additions from the VMM console
Use PowerShell

Let's see how each method is carried on:

Using VMRC Plus to Install the VM Additions

If you've got VMRC Plus installed you can easily install VM Additions by performing these steps:

In the VMRC Plus console, point to the virtual machine you want to install the VM Additions on, and then double-click it to turn it on.
Once the virtual machine has started, point to the virtual machine name, and then double-click it to remote control it.
Log on to the virtual machine as an administrator or member of the Administrators group.
Once the guest operating system is loaded, in the Console Manager window click Media > Install Current VM Additions.
Inside the VM, follow the prompts and perform the installation.
You must *reboot the guest virtual machine* in order for the VM Additions to function properly.

Using the Virtual Server administrative website to Install the VM Additions

To install Virtual Machine Additions through the Virtual Server administrative website please follow these steps:

Open the *Virtual Server Administration website.*
In the navigation pane, under Virtual Machines, point to Configure and then *click the appropriate virtual machine. *
In Status, point to the *virtual machine name*, and then click Turn On.
Once the virtual machine has started, *point to the virtual machine name*, and then click Remote Control.
Log on to the virtual machine as an administrator or member of the Administrators group.
Once the guest operating system is loaded, press the HOST KEY to release the mouse pointer, and then in the lower-left corner under Navigation, click Configure virtual_machine_name, where virtual_machine_name is the name of the VM you wish to install the VM Additions on.
In Configuration, click *Virtual Machine Additions,* click *Install Virtual Machine Additions,* and then click OK.
Under Status, point to the *virtual machine name, *and then click Remote Control.
Click in the Remote Control window to return to the guest operating system. The Virtual Machine Additions installation wizard will start. Proceed through the wizard.
Once the wizard is complete, you will be prompted to restart the virtual machine to complete the installation.

Using Unattended Installation to Install the VM Additions

To perform an unattended installation, place the Virtual Machine Additions image file (.ISO) to a location where it can be accessed by the virtual machines. Logon to the VM and in a command prompt window from within the VM type the following command:

setup.exe -s -v"/qn [Reboot=ReallySuppress]"

Using Scripted Installation to Install the VM Additions

The script to install Virtual Machine Additions in a running guest OS is fairly straightforward, but for a good scripting guide I suggest you look at Desmond Lee's excellent article:

2005 R2, Part 2

Using the SCVMM Administrator Console to Install the VM Additions

First, it is recommended that you add the Virtual Machine Additions to your VMM Library. This will allow you to use the same ISO image for all of your virtual machines.

To add Virtual Machine Additions to your VMM Library:

Copy the VMAdditions.iso file to a share in the *Virtual Machine Manager library* and then refresh the library server. The default location is C:'Program Files'Microsoft Virtual *Server*'*Virtual* Machine Additions.
If you do not see the VMAdditions ISO file in Library view or when you browse for a known image file, disable any filters and manually refresh the library.

To install Virtual Machine Additions on an existing virtual machine:

In Virtual Machines view, right-click the *virtual machine* on which you want to install Virtual Machine Additions, and then click Properties
In the Virtual Machine Properties dialog box, display the Hardware Configuration tab.
If there is no DVD drive, add a DVD drive to the IDE device by clicking DVD on the New menu bar to add one.
Click K*nown image file,* click Browse to open the Select ISO dialog box, click the VMAdditions.iso file, and then click OK.
Start the virtual machine. Virtual Machine Additions will install from within the running virtual machine.

Using SCVMM and PowerShell to Install the VM Additions

Coming from this blog - VMM Beta 2: Installing VM Additions:

Here is a PowerShell script you can run on the VMM server that will do that. It assumes that you have an ISO called VMAdditions.iso in a library share managed by VMM. The VM Additions are installed with Virtual Server 2005 R2 SP1 in the <yourinstalldrive>'Program Files'Microsoft Virtual *Server*'*Virtual* Machine Additions folder. So you first either copy this ISO to the library for use on all VMs, or modify the script to use the copy local to the host your VM is on.

Copy the following text and save it as Install-VMAdditions.ps1:

# Install-VMAdditions.ps1 $vm = $args[0] if ($vm.Status -eq ‘Running' ) { $vmadditions = get-iso | where { $_.Name -eq ‘VMAdditions' } Set-VirtualDVDDrive -VirtualDVDDrive $vm.VirtualDVDDrives[0] -Link -ISO $vmadditions } else { write-host "The VM must be Running before you can install VM Additions." }

To use this script:

$vm = get-vm -Name "My VM" C:'Scripts'Install-VMAdditions.ps1 $vm

The VM Additions installer will launch automatically inside the guest OS.

Notes:

The VM does not need to be running order to attach an ISO to a Virtual DVD drive, but the VM does need to be running in order to install VM Additions.
On the Set-VirtualDVDDrive lines, the -Link¬ parameter means: Point to the ISO inside the library instead of copying it to the host.

Reinstalling Virtual Machine Additions for use with Virtual PC

If you move a virtual machine that was created with Microsoft Virtual PC to Virtual Server, we recommend that you reinstall Virtual Machine Additions, even if it was installed in Virtual PC. This is because the version of Virtual Machine Additions included with Virtual Server has been updated.

Current VM Addition versions are:

VM Additions in VS 2005 R2 SP1 = 13.813
VM Additions in VPC 2007= 13.803

Warnings on virtual machine memory usage

walterD — Thu, 12 Nov 2009 12:16:25 GMT

Hello,
Have a question about the difference between ESX 3.5 and vSphere 4. I have 4 ESX 3.5 and 2 vSphere 4. On the ESX 3.5 the memory usage is clearly lower then on the ESX 4 for the same virtual machine.
Example : SVR2003 TS with average of 20 users configured the same, running the same application.

On the ESX 3.5 : HP Prolaint DL380 G5 with 16 GB memory, dual processors running on 3 GHz (4 logical processors no Hyperthreading)
Memory Granted : 2.134.016 KB Average
Memory Active : 313.342,33 KB Average

On the ESX 4 (vSphere) HP Proliant DL380 G6 with 16 GB memory, Quad processors running on 2,8 GHz (16 logical processors with Hyperthreading)
Memory Granted : 2.097.152 KB Average
Memory Active : 1.987.864,5 KB Average

As you can see there is a big difference in mem usage. We therefore always get alerts and warning from our virtual center whiel I cannot find anything wrong on the config from the virtual servers, as well on the vmware machine.

Does anybody had the same problem, and what can we do about it ..

THX

Walter

Windows 7 support?

yougotiger0 — Mon, 16 Nov 2009 23:29:10 GMT

Right now when adding a Windows 7 VM to our vSphere host, Windows 7 is listed as 'experimental'. Is there an ETA on when this will no longer be experimental and be officially supported?

When you're done . . .

DSTAVERT — Thu, 19 Nov 2009 23:00:14 GMT

There are often times that a user is stuck with a setup or configuration issue and a simple diagram would be a huge help in getting the idea across. It would be really nice to have something like http://www.gliffy.com/ or perhaps better http://www.onlinesketchpad.com to actually create and embed a simple drawing. Again no hurry. When you're done the other stuff.

Server 2008 x64 Memory issues - VM using all available memory for system cache

Bill.Morton — Fri, 29 May 2009 20:28:33 GMT

I have just deployed my first Windows Server 2008 into the cluster, running
SQL 2008 and I am having a big problem with memory. I have allocated 8GB of
memory to the virtual machine, of which SQL and the normal processes only use
about 5GB. The problem is that Server 2008 is using all of the extra memory to
cache 'junk' which is causing the entire set of memory to be used, all of it
unique, and active. Our other VMs (Server 2000, 2003, etc) do not show
this behavior and benefit greatly from memory sharing, and inactive page penalties
built into ESX.

I experienced this same issue with Vista on my workstation and I was
able to resolve it by turning off superfetch and pre-cache, but super fetch is
already disabled on server 2008, and the registry key values I used on Vista do
not appear on server 2008.

Does anyone have experience making server 2008 play nice with memory
in a virtual environment and not hog everything? I want to leave enough
headroom for load spikes, but if the OS fills all the available free memory
with system cache junk we will have a huge problem as we migrate to more 2008
servers as memory is our most scarce cluster resource. There is alot of information about this problem with Vista, but nothing with server 2008, perhaps it is too new to be well implemented in VM environments.

what's wrong with the bridged network option?

dagobert39duck — Fri, 20 Nov 2009 19:06:05 GMT

I have an intel iMac with 2.5 GB RAM running Snow Leopard, I recently installed VMware Fusion 3.0 and installed both Windows 7 and OpenSuse as guest operating systems. Everything seems to work fine when I use the NAT option for networking. Whenever I try to use a bridged network neither internet nor communication between the mac and either of the 2 guests is possible (I only run one guest at the time). The system seems to create an "unknown public network" which impedes all communication.

Does anybody know what could be the cause of this?

Thanks in advance.

Allocate 4 vCPU to Windows 7????

shalpern — Fri, 20 Nov 2009 16:30:35 GMT

We are getting a stats program that can run on Xp/Win7 x64. It really needs a Quad core CPU to run efectively, but the OS only allows for 2 physcal processors. Is there a way to make it look like the virtual machine has 4 vCPU?

VI3: Linux Client, Please

nick.couchman — Fri, 21 Jul 2006 19:21:04 GMT

Well, I've seen several threads around here asking about VirtualCenter support for Linux, which I think is a great idea. I recently downloaded an evaluation copy of ESX3 (VI3 - whatever you'd like to call it) as a proof-of-concept for my boss. I was floored when I found out that there is no ESX3 Client/Console (or "Virtual Infrastructure Client" if you'd like to call it that) for Linux. Are you kidding?! Please, VMware, take this request seriously - there are quite a few of us Linux guys out here running ESX that don't want to also have to run Windows inside of Player or Workstation on their local PC's just so they can manage ESX3. Please, get a Linux client/console for ESX3 out soon (as well as the Linux VC clients that have already been mentioed).

Expected vSwitch/vmxnet network performance?

pocomo — Sat, 24 Jan 2009 14:30:06 GMT

Hello -

I'm doing some network debugging using 2 CentOS 5.2 64-bit VMs on ESXi 3.5u3. The VMs each are using 1 "enhanced vmxnet" NIC connected to a "virtual only" vSwitch (no physical NIC for this vSwitch). Everything is running at 1000/Full. All other VMs on the ESX host are powered off.

VM -> VM network testing with iperf, results do not seem good @ 321 mbit/s

VirtualCenter permissions problem

VRADlab — Thu, 26 Feb 2009 23:41:37 GMT

Hello, hoping for some help on this one. The previous administrator left me in a bit of a bind.

For a folder in virtualcenter he assigned the "No Access" role to the local group "Users." He intended to prevent non-administrators from accessing this folder but it also applied the deny to the "Administrator" user. For now the workaround is to connect to the individual ESX servers as root and manually control the VMs, but this is not ideal. Can I somehow override this deny permission (even though it's a deny on the administrator account so I have no idea how to escalate priveledges even higher...)?

Is there a way to delete a deny permission on the local administrator account manually?

I was incorrect in my initial description. It's not a folder but two
VMs that I cannot access. I can see the folder just fine but it has two
VMs in it that I cannot reach because they each have No Access set for
the Users group.

I recently used the VMWare Converter Standalone Client 4.01 to p2v my own Windows XP SP3 machine and import it into our ESXi 4.0 server. The conversion completes without any errors but when I try to boot the VM, it says "error loading operating system."

This is the first time I've used the converter, so any advice here?

Thanks, Jay

VMware-Tools fail after SLES10-SP3 Update

hackenhans — Wed, 18 Nov 2009 09:36:46 GMT

Hi,

VMware-Tools work fine in SLES10-SP2 guest even with VMXNET3-NIC. But after update to SP3, there is no chance to start the tools, neither with FLEXIBLE-type nor with VMXNET3-type. It always fails with the following message:

- - - - - - - - - - - - - - - -

Starting VMware Tools services in the virtual machine:
Switching to guest configuration: done
Paravirtual SCSI module: failed
Guest memory manager: done
Guest vmxnet fast network device: failed
VM communication interface: done
VM communication interface socket family: done
Guest operating system daemon: done
Unable to start services for VMware Tools

- - - - - - - - - - - - - - -

The only way to get the nic working is to change the adapter type from VMXNET3 to FLEXIBLE before start updating. The pcnet32 module loads properly in the new environmen, the vmxnet3 module doesn't. What's required to get it working

Thanks in advance

Scanning guest os, host ports respond

FiremanE63 — Thu, 19 Nov 2009 22:33:43 GMT

Hello,

I am seeing is issue where if I do a network scan or nmap of a guest OS on ESXi 4 I also get back ports that the Host has open. I also get results when the guest is shutdown. Any one have any ideas on why this happens. It did not alway happen and I have not updated the ESXi host between when it did give me the results I expect and now. I can connect to port 80 (even when guest is shut down) and it does respond but looks like the ESXi host. This happens on every guest that is on this ESXi host.

Nmap results from guest on same ESXi host:

Interesting ports on 192.168.X.X:

Slow performance of Virtual Machine

singhpdeep0007 — Fri, 20 Nov 2009 04:40:49 GMT

I have a ESXi4 and which is mapped with iSCSI Storage and one top of that I have created on new Virtual Machine of Windows 2003, 64 bit but the Virtual machine tooks more than 10 min to boot up once i start the virtual machine. and even we have the same virtual machine on ESX1 3.5 which is booting very fast.
Please let me give some tips how can my virutal machine boot up fast.

Multiple physical servers combined into one virtual server

MWorsham2120 — Thu, 19 Nov 2009 16:15:40 GMT

Hello. I am new to virtualization technology and am working to evaluate the VMWare software suite for my organization. So far, I have been able to create several virtual servers using one physical server with VMWare Server, but I am looking to do the opposite.

I am looking for a solution whereby I can take 2 or more physical servers and combine them into a single virtual server. The idea being that the virtual server running our applications will stay up and online in the event of a failure of any one physical machine. Is this possible? Any information would be greatly appreciated. Thanks!

Connect virtual machine directly to LUN

Arkady — Thu, 15 Oct 2009 20:47:36 GMT

Hi.

We have a physical file server (Windows 2003 R2) which connects to a LUN on SAN.

Is is possible to connect virtual machine to the same LUN and be able to read data?

Thank you in advance!

Why Intel-VT/AMD-V for 64 Bit guests?

AWo — Fri, 18 Apr 2008 10:57:19 GMT

From the ESX 3.5 Supported Guest Operating Systems:

"There are specific hardware requirements for 64-bit guest operating system support. For AMD Opteron-based systems, the processors must be Opteron Rev E and later. For Intel Xeon-based systems, the processors must include support for Intel Virtualization Technology (VT). Many servers that include CPUs with VT support might ship with VT disabled by default, and VT must be enabled manually. If your CPUs support VT but you do not see this option in the BIOS, contact your vendor to request a BIOS version that lets you enable VT support."

I think I know what Intel-VT and AMD-V is for. But I do not know why running 64 Bit guests require VT technologie? I thought 64 Bit should be independent from VT.

Can someone explain the relationship, please?

Possible to extend C:(system drive) when deploying VM from template?

MicroAdmin — Thu, 11 Dec 2008 18:58:14 GMT

Going with the reccomendation of my instructor for my last VMware course I created my Windows 2003 templates with a 10GB system drive so that I'm not wasting space with the template.

My problem is that I need to make the system drive more than 10GB when I deploy a VM. When I increase the size after deploying the VM, Windows just sees another partition and I can't combine it in to the "C:" drive.

Is there a way to fix this so I can have a 40GB C drive instead of being stuck with 10GB?

Isolating the host from the internet

UlyssesOfEpirus — Tue, 17 Nov 2009 11:34:22 GMT

I have been trying to isolate my host from the internet. Until recently this was done by plugging a USB router to the VM, and unplugging the ethernet cable from the host. That's ok for one VM at a time, but now I need to provide internet access to several VM's simultaneously. Any secure ways to do that without giving internet access to the host?

I was thinking of setting the USB VM as a gateway over a virtual network. But it can't be the host-only network because that would give internet access to the host too. Is there any other way?

PETITION - Native Mac version of the VI Client

virek — Thu, 28 Feb 2008 07:26:42 GMT

Copied from the Fusion forum...here's a better place I think.

I'm going to start this old chestnut again...

I'm here at VMWorld 2008, Cannes and I got talking to a couple of people. Now I'm not claiming any inside knowledge or anything but I'm guessing a petition with enough response will make VMware think seriously about doing a native mac VI Client.

I'm sure, like me, there are many of you who use the mac daily who also deploy, maintain, train and troubleshoot VI3, and booting an XP vm just to do that is well...a PITA.

So please, join in.

VMware is still one of those rare-breed companies that 'actually' listen to their customers, unlike others that say they do, but...don't.

In the old forum you were able to look at most sentences without the sentence being wrapped to the next line. In the new version the editor/text area (I don't know how to call it exactly) got smaller and the text is harder to read due to the wraps.

I'm running 2.6.24-22-server at the moment and ubuntu has just updated to 2.6.24-23-server.

Is it possible with vmware-tool-config or manually to pre-compile the vmware modules tools before rebooting? The appropiate kernel headers have been installed.

vShield - No cluster option

Mickoni — Thu, 19 Nov 2009 15:13:08 GMT

Hopefully this is a simple one......

I have 3xESXi 4.0 hosts in a DRS cluster. I have followed the VMware instructions as much as possible but im obvisouly doing something wrong.

I have installed vShield manually (on a distributed switch) and vShield manager (is currently located on a vSwitch) and am getting connectivity ok. However, when doing a manual install through vShield Manager. I ONLY have the option "Standalone" in the Clustering Settings. In the guide it says I should have a "Add to Cluster" option - which just isnt visible. This obviously just leaves me with 1 host being protected.

Any ideas?!

Install issue - XP Pro on ESXi 3.5

mtooze — Thu, 19 Nov 2009 19:29:14 GMT

Hello everyone. I've been pouring over the forums and can't quite find the answer I'm looking for. I'm trying to install XP Pro on ESXi 3.5.

Here's where I'm at.

Placed XP ISO on the datastore
Placed the Buslogic and LSI .flp on the datastore
Created a VM selecting LSO as the controller
Atatched the .flp to the floppy drive
Mounted XP iso and booted to CD
Hit F6 and select the LSI driver it presented
Format disc, then says it making a list of files to copy and an error pops up saying it can't find the .sys files that are on the floppy. I didn't disconnect it. I hot ESC to continue and it lists all the files on the floppy, but it can't copy them.

Any idea what the problem is? Thanks.

ESRI ArcGIS As A VM

jjahns — Fri, 18 Sep 2009 04:29:43 GMT

I was just wondering if there is anyone out there who has implemented ArcGIS in a virtual machine. We have been doing this for approximately 1 year now, and so far have been extremely happy. Recently, after the vSphere 4 update and discussions from vmworld, I took the opportunity to restructure our datastores. We use a Compellent SAN, so on the actual GIS VM, we changed a few things.

LDFs are on a separate datastore pointing to FC RAID 10 disks.
Data, OS, and MDFs are on the main datastore (separate VMDKs) pointing to FC RAID 10 disks, then migrating down to FC RAID-5-5, then to SATA disks at RAID 5-5.

Upon doing this, I noticed a massive performance improvement (on top of what we already had gotten over physical). Before, we had LDFs and MDFs as RDMs pointing to FC RAID 10 disks. I found this a bit odd, but went with it. It was, after all, an experiment. The only caveat we have is that the database resides on SQL 2000. I don't really like SQL 2000 on a VM, and have gotten better performance running SQL 2005. Aside from that, everything is great.

So... anyone else out there that has tried this endeavor? By the way, we also virtualize Informix 10 and are extremely happy with this.

Thanks.

Giving students access to applications

serembanboy — Wed, 18 Nov 2009 18:54:05 GMT

Hello everyone. I'm new to VMware and I have a few questions with regards to
which VMware product I should look at as a solution for my needs.

I work at a university that's moving towards a mobile computing environment.
At some point we expect all our students to own a laptop/notebook. The laptops
will be used both for schoolwork and personal use. When we reach that point
where all our students own a laptop, we’re planning on closing down the computer
labs we have on campus.

The repercussion of that is, students will lose access to the applications
that were available in those labs. This would include applications such as SPSS,
SAM 2003, Studio 9, etc.

As a solution we were wondering if we could “push” these applications to the
laptops. These applications would have to be available 24/7 while the students
are on campus.

What VMware product can help us do this? Thin client, thick client? How well
will it work over wireless network? We have n capable access points.

Thank You.

Chelvan.

Can encryption beat a man in the middle attack?

UlyssesOfEpirus — Wed, 18 Nov 2009 02:17:19 GMT

If I could get physical access to a server and store a few GB of truly random text onto the server (or somehow connect and transfer the text to it at a time when there is NO man-in-the-middle scheme going on), I could then program a special proxy in the server so that the link between me and the proxy is encrypted by simply XORing the data with the random text according to the one-time pad method. Then it is impossible to break the encryption, but it is also impossible for a man in the middle to harm me by directing me to another server of theirs, because that other server would not have a copy of the secret random text so there could be no communication.

1. Can the same be achieved by conventional encryption schemes like SSL or PGP where I do NOT have physical access to a proxy?

2. Can an authentication with these conventional schemes occur somewhere where there is NO man-in-the-middle attack going on, at a cafe or something, and then continue my encrypted access at a place where I know there most likely is a man-in-the-middle attack going on?

Connect LUN directly to Physical from Virtual Machine

Hi ,

We have a senario wherein we need to present the Raw LUNs to windows machine, copy the drives data and present back the same LUNs to physical box.
Can anyone has a experience on such senario...will we able to maintain the data copied or physical box need to format the LUNs once presented?

Can malware in the guest access NON-shared folders?

UlyssesOfEpirus — Fri, 06 Nov 2009 05:25:40 GMT

I do not mind if shared folders are written to by any malware running in the guest, but is it possible that malware can also access folders other than the shared ones?

Can malware running in the guest do anything else to harm the host, other than messing with the contents of the shared folders?

Using 1 SAN for both LAN and DMZ

ITAV — Tue, 25 Aug 2009 19:30:44 GMT

So I have been trying to fnd answers or thoughts on the issue of using 1 SAN for both my internal VM's and my VM's that reside inside my DMZ. Currently we have 2 SAN's 1 in each network segment but we are being re-orginized and one of the SAN's needs to move. The result is that my VM's that run on the inside LAN now have no home. I can split my DMZ and LAN up within my SAN but is that a good idea? I am trying to convince them to just purchase a new SAN because everyone has that kind of money laying around... right. I am also trying to find any reason to not mess with my production environment if I dont have to.

Thanks,

ITAV

2 vCPUs Hardware Interupts

Wadebum — Thu, 15 Oct 2009 21:24:08 GMT

We have decided to move our Oracle Forms servers to VMs. We built a 2 vCPU with 4GB of Ram Windows 2003 SP2 VM on a new ESX 3.5 host using its own LUN on a EVA8100. Our DBAs started to do some forms compiling on the VM and noticed that it was taking around 4 times longer on the VM than it does on physical servers. They wanted me to add more CPUs so I added 2 bringing the server up to 4 total. I watched the performance as they reran the forms compiling and noticed that the actual process doing the compiling was only using about 25% of the CPU (my thinking is that the process does not take advantage of multiple cores). I put the server back down to 2 vCPUs and after rerunning the compile it was using about 50% CPU (adding to my suspicion that it does not take advantage of multiple cores).

Since it was a new Oracle install we thought maybe there is something diffrent between the physical server and the VM, so I did a test with a script that gathers all the email addresses in our Active Directory and puts them in a file. I added a function to the script to put a time stamp at the top and bottom of the file so I could compare between the physical and virtual server. The physical server finished the script in around 6.5 min but the virtual server took around 16-17 min to finish the AD script.

Since we were about to upgrade to ESX 4 we decided not to spend much more time figuring this out. Our upgrade to ESX 4 is now complete and I have upgraded the VMware Tools and Hardware of the VM to the latest versions. It still takes around 16-17min to run the AD script.

I then built a brand new VM with 1 vCPU and 1GB of Ram in the same LUN as the origional server and installed Windows 2003 SP2 onto it and installed the VMware tools. After that I ran the AD script 5 times and it finished on average at just under 5 minutes. I then installed all available WIndows Updates and ran the AD script again with no significant time increase.

Next I shutdown the VM and added a vCPU. After finding the new hardware I ran the AD script 5 more times with an average around 17min. I watched the server with Process Explorer and the Hardware Interupts are running around 20% the entire time the script is running. I used KernView to see what was going on in the Kernal of Windows and I get processor, ntkrnlpa, hal, tcpip, win32k, e1000325, ndis, afd, fltmgr, and ntfs as the top 10 items.

Using Process Explorer on the Physical Server shows the Hardware Interupts around 2% at the highest.

I have gone so far as to make this the only VM running on an HP BL465 G5 with 2 Quad Core AMD 2.7GHz processors and 32GB of ram and setting up CPU and Memory reservations to what the VM has but it does not perform any better. Does anyone have any idea how to get better performance out of a VM with multiple vCPUs? Or why the Hardware Interrupts are so high?

Inability to extend boot partition of win2003 on GSX 3.0.1 client server

mattabah — Thu, 19 Nov 2009 09:08:11 GMT

Hello great pals,
I have a problem on how to increase the boot/system partition of all my win2003 vm Clients, all seating on a win2000 VMWARE GSX 3.0.1 Host Server.
I have Eight (8) Guest servers: 4 running Win2000 and the other 4 on Win2003. I used Vmware-Vdiskmanager.exe to entend both Boot/System and Data partions of all the win2000 client boxes, as well as all the data(E:\) partitions on all the win2003 client boxes. My Challenge/difficulty is on the Boot/Windows system partition of all the win2003 client servers. After growinging their respective sizes, I used diskpart.exe to extend but.....to my surprise, Disk Mangement able to recognise the newly increased size but Windows could not see the newly increased sizes. It shows/sees it as they were.
From online support and researches, I have used gparted-livecd-0.3.4-10 and KNOPPIX_V5.0.1CD-2006-06-01-EN, while booting with them from cd-rom. When booted and executed, they see these extended sizes. Yet nothing is really effected. See attached images. Could someone kindly help out on how to makje windows see the new increment?

Regards.
Matt Abah.

Performance issue using virtualization

sispeo — Fri, 16 Oct 2009 14:39:27 GMT

When comparing our software installed in a physical host and in a comparable VM (same CPU, memory), we notice that the product is two times slower when running in a VM (Guest OS is Windows 2003, using an ESXi 4.0 host. Software uses only one CPU)

As we are not in production environnement, we tried with all others VM powered off. We tested our VM with and without CPU reservation (best results with), with and without memory (quite no difference), and with 1, 2 and 4 vCPU

After several tests, it seems that the problem comes from usage of semaphores : when replacing them by critical sections (but we can't replace all), performances are quite the same between the physical host and the VM. All code is executed with similar performances but when using semaphores, the VM consumes CPU longer than the physical host.

Does anyone already eared something about such a problem ? Is there a reason to explain bad performances when using semaphores under Windows hosted by ESXi 4.0 ?

For example, we wrote a simple program to benchmark semaphores under Windows hosted by ESX (in our lab, it took 10sec on a physical host and 22sec in a VM) :

#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
unsigned __int64 nCount;
DWORD nTickCount = ::GetTickCount();
HANDLE hSemaphoreBridgets = CreateSemaphore(NULL, 1, 1, NULL);

for (nCount = 0; nCount < 10000000; ++nCount)
{
WaitForSingleObject(hSemaphoreBridgets, INFINITE);
ReleaseSemaphore(hSemaphoreBridgets, 1, NULL);
}
printf("Duration %d s\r\n", (::GetTickCount() - nTickCount) / 1000);
CloseHandle(hSemaphoreBridgets);

return 0;
}

Problem : Task Manager doesn't show 2 CPU.

This VM was migrated from a VMware Server 2.0 by VMware Converter Standalone 4.0.1, and if I add 1 to 2 Vcpu, or 4 Vcpu, task manager still showing only one CPU.

Running VC, selecting the machine, performance TAB, I can see CPU 0 and CPU 1, but CPU shows minimal utilization.

I attached 1 document with 2 images, one is the task manager and the other Virtual Center.

Fax Modem with MS Server 2008

Compex2 — Wed, 18 Nov 2009 20:29:01 GMT

I need to setup a fax modem with Microsoft Server 2008 running on ESX, Currently we have not been able to find a solution. We have tried a Startech USB server, however it did not support the modem, We have also tried a Startech Serial to IP ethernet which was working in XP but will not work with Server 2008, Has anyone been able to get this working, and if so how? Thanks!

Backups VMs while they are running?

Is it safe to backup VMs while they are running? Or do I have to shut them down before backing them up?

Use LLDP as well as CDP in VI Client's Network Details view

gclinch — Tue, 11 Mar 2008 15:11:30 GMT

Unfortunately our environment does not support Cisco's proprietary discovery protocol CDP, but all our edge devices do support the vendor-neutral protocol LLDP - it'd be really nice if the VI client's display of networking details could be extended to include details from LLDP as well as CDP.

Dual boot

cl0ne — Mon, 16 Nov 2009 04:48:59 GMT

Hello everyone,

I have Windows Xp on my host machine but I would like to dual boot Xp and Fedora in vmware. Can someone please explain the step-by-step procedure on how to do this? This is purely for learning purposes. I found the following link (http://www.vmware.com/support/ws5/doc/disks_dualmult_ws.html) but it did not help much because I was thrown off by the terms used, like raw disc. Please let me know if I need another HDD in order to do this. I only have one HDD which I have partitioned.

Thanks a bunch!

Iomega StorCenter ix4-200d NAS Server performance?

khughes — Tue, 08 Sep 2009 20:18:08 GMT

I was curious if anyone is running the Iomega StorCenter ix4-200d NAS Server? I'm planning on maybe picking one up for our R/D and DR testing but was wondering how the performance was. Granted I'm not going to be running production on it, and using it mainly for proof of concept and testing but how much can 4 spindles really run?

Server load and amount of Vitrual Machines.

dmanrez — Wed, 18 Nov 2009 17:31:32 GMT

Hi

Is there a way of finding out the amount of vitrual machine I can load onto a host esx server. My boss wants to know how many virtual machine I can load onto one host esx server before we pay additional storage.

Thanks

Oracle RAC - Cannot Ping from RAC1 to RAC2

tadcs — Wed, 18 Nov 2009 11:02:50 GMT

Hi all,

I've created two VMs (RAC1 and RAC2) on VMware Server2 for Oracle 10g RAC.
Each VM has 2 network adapters:

eth0: public
eth1: private

But, Into RAC1, when I try a ping to RAC2, I got the error destination host unreachable.
The subnet and the net mask is OK, I've set the /etc/hosts.

From my Host PC, I cannot to perform ping to RAC1 and RAC2 too.

I've tryed to set the ethernet to hostonly and bridged, but I got the same problem.

Is there any configuration we need to do?

thank you very much!!!!

Maximum No. of Virtual CPU's recommended

gmreddy — Tue, 17 Nov 2009 13:20:19 GMT

Hi,

We have a Virtual Machine (windows 2003) hosted on ESX 3 environment. VM configuration is 2 vCPU and 8 GB RAM.
This is a Database server and it is very very slow; average cpu utilization is above 80% always.

I proposed to increase the vCPU on this machine from 2 to 4 but my senior is opposing the same and he is telling some negative implications will be there if we increase vCPU.

Please let me know what will happen if I increase the vCPU and what are the negative implications.

Regards,
GMR

VMWare and IaaS (WAN)

TechMonkeys — Fri, 13 Nov 2009 23:20:35 GMT

Hey Everyone,

I've been doing lots of research, and starting to get an understanding of all of this technology. But I have some questions, and where better to get the answers!

It would appear with the new PCoIP technology, providing a virtual desktop over a WAN connection (<150ms) is now more than feasible. So it's planted an idea in my head to provide mico and small businesses a complete manage IT infrastrucure. By setting their office up with only an Internet connection and thin-clients, I'd like to provide them with the full "private network" experience but virtually.

Where I'm getting confused is more what VMWare products I need to use! View 4 seems to be the one with the PCoIP technology, so I would want that to provide the actual desktops. But vSphere 4 seems to be the one I want to use to set up private network, server management, etc. Is this correct, or does vSphere provide the desktop experience with PCoIP as well? Or does View work under vSphere? So confusing!

Essentially my concept is to have a number of servers in a local datacenter (to get the sub 150ms pings), and then virtualise a Windows Server, Network, and 1-10 PCs to provide to a business. But if I have two micro businesses, and want to host them all off of the one physical server, can I virtualise two seperate private networks?

I guess my main questions are:

1) Do I look at using vSphere, View or both?

2) Is it possible to emulate a complete private infrastructure (server/network/etc), and can more then one be done on a physical server?

I'm sure there's more questions, but hopefully this becomes a resourceful discussions and we can sort it all out! If you're wondering "why not just set it up on site", I'm more chasing the concept that I can monopolise on hardware and serve 2-3, or more, business on the one physical server. That way the businesses only get the costs of setting up thin-clients, and none of the server setup costs.

Thanks in advanced,

Chris

how to autoload guest on reboot?

kourkoutsavlos — Wed, 18 Nov 2009 06:28:49 GMT

SCSI errors on VMs on NFS datastores

deltajoka — Tue, 20 Oct 2009 15:17:22 GMT

Hi,

We have recently been experiencing some problems with our VMs on NFS datastores on a IBM N series/NetApp filer. We have about 5 to 10 short incidents per month where VMs (simultaneously on multiple ESX hosts) are experiencing some kind of scsi "lag"/timeout. The following types of messages are then logged on the console (and in the kern.log) during these "glitches":

mptscsih: ioc0: attempting task abort! (sc=de2e0280)
mptbase: ioc0: IOCStatus(0x004b): SCSI IOC Terminated
mptscsih: ioc0: task abort: SUCCESS (sc=de2e0280)
mptbase: ioc0: IOCStatus(0x0002): Busy
mptbase: ioc0: IOCStatus(0x0002): Busy

Usually, some (sometimes only one host, sometimes several, even though VMs on all hosts are affected) of the ESX hosts are logging single occurrances of the following type of nfs-related errors:

esx03 vmkernel: 118:20:41:44.851 cpu1:1110)WARNING: NFS: 4590: Can't find call with serial number -2146566064
esx04 kernel: nfs_statfs64: statfs error = 5
esx01 kernel: nfs_statfs: statfs error = 5

We have been investigating counters on the switches and on the filer. There seem to be some retransmitting of tcp packets occurring, but no dropped packages or packages with bad headers/invalid checksums or similar.

If these problems would be the result of high IO or latency on the filer, wouldn't the effect be slower transfers rather than VMs simply "losing" their disks for a short period of time?

The ESX hosts are HP DL360 G5, running ESX 3.5u4. The switches are Cisco 2960 (gigabit), with flow control disabled.

Any input on this matter is most welcomed!

Connect a VM to external storage?

pommierr — Tue, 17 Nov 2009 19:06:43 GMT

We have a file server attached to a SAN that we would like to virtualize. Is it possible to P2V the server and connect the VM back to the SAN? Or should I just create another drive in the VM and copy the data from the SAN to it?

Thanks,

Cloning issue a Windows 2008 VM ID.

digitaex — Sat, 14 Nov 2009 01:10:53 GMT

We successfully cloned a Windows 2008 VM but we cannot clear the Computer ID. WSUS keeps seeing the server as the previous machine. It has a new SID from adding it to the domain but the computer ID is the same. We tried the vm configuration wizard but that didnt work. We tried using sysprep but it gets a fatal error attempting to prep the OS. Is there another way or a tool that will help us reset the computer ID on this Windows 2008 VM?

Understanding the VMmark Results

eMax04 — Tue, 17 Nov 2009 14:32:53 GMT

Hello all!

I have successfully ran a full VMmark benchmark test and am looking to get some more information about the results, and how to improve them.

The Numbers generated are very vague and the doc I have doesnt say much about how the numbers are calculated. I am looking for some type of calculation that VMmark uses to get the end results. I assume it is somthing like IOPS/total transactions ......etc....

I have a single quad core CPU server with 16 GB of Ram. I am using a back end SAN and am looking to really test the back end SAN vs any of the other components of this.

If anyone has any tips they would be appreciated!!

Thank you in advance!!

hi,
when I install win2008 R2 in VM i see that my only option is to install the experimental tools for 2008 R2.
Since 2008 R2 is out now, how can I check or download the proper tools for it and not the experimental one I have.
the same goes for windows 7

WinRegKeys enabled when using VMachine?

gguay — Mon, 16 Nov 2009 15:25:51 GMT

Hi guys,

I am sure it is trivial for you experts but since I am fairly new to VMware I am still ramping-up.

I need to know what would be the WinRegKeys to look for in order to
know if a user is coming from a VMachine or a Native Desktop.

Actually my goal is to use an End-Point Profiler agent that would be
able to query the specific WinRegKeys to not allow a user session if it
is coming from a VMachine. Only a user coming from a Native Windows or
Linux Destop could access to a specific portal.

Since my End-Point Profiler agent is able to query WinRegKeys, files,
process, etc. I would like to know what are those WinRegKeys and the
status to look for in order to know if it is a VMachine session or
Native.

I saw there are some RegKeys under a VMware Workstation running Windows2003 server which have VMware RegKeys like this:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\VMware Tools Service

HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Tools

but I don't know which key to look for and the value it should be when it is running on a VMachine

Ideally, I would like to have those for any kind of Client VMachine like:

[/products/view/]
[/products/thinapp/]
[/products/ace/]
[/products/workstation/]
[/products/player/]

Thanks in advance if anyone know this.

best practise on iSCSI initiator Multipath inside a VM

sgul — Mon, 16 Nov 2009 05:50:40 GMT

Hi,
Could someone comment on the best practise on using Multipathing inside a Win2008 VM.

I'm wondering if there is any speed or performance gains if I setup two vNIC's and then enable Multipathing on them via the iSCSI initiator.

We're connecting to iSCSI volumes on an Equallogic array.

Appreciate any comments and thoughts.

cheers

Anyone try Windows 2008 R2 in ESX 4 yet?

cypherx — Tue, 29 Sep 2009 14:29:08 GMT

I have the RTM of Windows 2008 R2 Standard (x64) in our ESX4 environment on a test network, along with a test xp client and a smoothwall linux based firewall/router to allow internet access from our main network into the test network.

Microsoft allows you to try Windows 2008 R2 and you can rearm the 10 day activation grace period 5 times, so you may use it for 50 days to try. I am evaluating this server to see how many licences we want to budget for next year, as we have some servers worth upgrading, and also I would like to up our Domain to 2008 R2.

However I am noticing through vSphere Client that the Windows 2008 R2 OS appears to freeze occasionally. It's happened when creating an OU, adding groups to a user, and even just sitting there doing nothing. It appears as if the mouse and keyboard have no effect. Even the num lock / caps lock states do not change when the guest is in focus. However the Windows XP client can still ping the machine and do remote registry, group policy, etc... so it's not as if the OS is hard locked.... just the I/O is locked. I'm not sure if vSphere is causing this to freeze, but I was just sending a reset to the guest and hard booting it to get working again. So now I enabled remote desktop and will work on this Guest O/S from the XP client via mstsc. I'll let you know if it freezes up that way, but I want to put this post out there to see if anyone else has had the same problem.

Recommendations for a good IPKVM

AlexTheBoss — Mon, 16 Nov 2009 18:28:21 GMT

I am needing an IP KVM that has the ability to either send or program special key strokes, such as F11, Alt+F1, etc. (keystrokes needed by the ESXi setup program). The one that I currently have doesn't work well. The one I have also doesn't do a good job of showing POST messages on some servers which is a problem. Any recommendations?

Annoying "move" verses "copy" question

jasimon9 — Tue, 17 Nov 2009 00:01:51 GMT

Many times I rename a VM and start it up. I get the annoying "move" verses "copy" question. The only reason it is annoying is because I never know which to choose, as a rename could be construed as either.

What is the correct choice for a "rename?"

iSCSI Connectivity

dwisby — Mon, 16 Nov 2009 14:49:18 GMT

I have a host configured with a vSwitch for iSCSI traffic. A VM guest is set up with RDM access to a volume on an iSCSI SAN. The connectiviy to the iSCSI SAN is available and functioning. However, connectivity from our Enterprise storage solution fails. From the VM we can ping all iSCSI devices except for the iSCSI ip on the host VM and no iSCSI device can ping the iSCSI ip on the host VM . This doesn't make sense, as I can access the iSCSI SAN via these iSCSI settings on the host. One night we were able to back up all the data on the SAN connected to the VM guest. The next night the backup servers could not connect to the VM hosts iSCSI IP.
Any ideas on what could be causing this anomaly?
Thanks for any assistance.

Performance on VDI (Windows XP Virtual Machines)

timjim88 — Sat, 29 Aug 2009 01:04:58 GMT

We have 2 ESX servers running VMWare Infrastructure 3. There are 32 GB a piece in each of these servers. We are also running fiber between our SAN and ESX servers (All VMs are on the SAN only). We run 66 Windows XP VMs in this environment with Wyse V10L thin clients. The thin clients use RDP to connect to our VMs. This environment is in a K-12 corporation.

Over the summer I rebuilt 2 of our thin client labs (total of 40 VMs). When I say "rebuild" I am meaning that I took an existing VM (VDI-XP18 for this example) and brought it off the domain. I then cloned it and began updating it (the clone). I went ahead and put VDI-XP18 back on the domain and let it run again. At that time I was working on the clone (renaming it of course) and installing SP3 for WinXP. Once this was done I cloned the VM to another one. The reason for this is to create my second image for another lab. Once both of my templates (at the time VMs) were built up I converted them with VMWare back to templates. I then deployed each template to the prospective labs. Everything was working fine in the summer (Keep in mind that when I say "working" I mean that when I booted up each VM I could get into them (RDP and on VIC) and things worked fine. Now that students are back everything is SLUGGISH. I look at the processes within the VM and on the ESX hosts themselves. Everything appears normal. I would say there is about 50% utilization.

Does anyone have any suggestions or ideas on why things may be sluggish all of a sudden? Both labs have Service Pack 3 now. One lab now has Office 2007, whereas before it was 2003. The other lab has SynchronEyes 7.0 (SmartTech Technologies). I did power down ALL VMs at one point. When booting up one lab at a time things were still sluggish. The 26 VMs that were never touched this summer work perfectly fine, indicating that something has gone wrong when I made the changes to the VMs.

Any help is GREATLY appreciated! By the way, I did also ensure that the VMs are divided up on the VNICs. 50% is on VNIC0 and 50% on VNIC1. This goes for both ESX hosts. Thanks!

Reahat 5 - CD/DVD Creator NOT working ESXi

Hi,

I am new to VMware ESXi, trying to evaluate it now. However, I am unable to burn CD onto either the VM host (CD/DVD writer), or the client machine (CD/DVD writer) .

On the CD/DVD creator window, I am able to select "write to Disc", it show me the virtual CDROM drive, and I can click on "write" , and it goes through the preparation, and eventually write to "complete", but it never automatically eject the CD. Unfortunately after all the work, NOTHING actually written to the CD !!

Does anyone have any clue to this ? or am I not doing the correct thing?

Thanks in advance

vCenter security - limiting devs to one Resource Pool

ouch — Wed, 11 Nov 2009 22:52:40 GMT

I'd like to set up a role that limits a team of developers to one resource pool. I'd like them to be able to create virtual machines, and modify them, upload files to the datastores, and generally do all the thing devs need to do, but keep them in a sandpit limited to a resource pool. I don't want them to be able to play with VMs in other resource pools, nor have admin access to other stuff within the vCenter Datacentre.

Is this possible, or should I create a second Datacentre and use that for the developers?

I am fairly new to vCentre, so feel free to correct any incorrect concepts in my thinking

Run away `top` in RHEL5 virtual machine

Brian Buchanan — Fri, 06 Nov 2009 19:54:23 GMT

I have a VM of a minimal install of RedHat Enterprise Linux 5.4 i386 on ESXi 4 (downloaded from hp.com) on a HP ProLiant DL380 G4.

CPU usage on the host is pretty excessive and I'm trying to figure out why. When I run `top` it goes crazy with refreshes as if I had set a delay of 0. If I set the delay to 60 `top -d 60` then I get updates about 1 per second.

If I run vmstat, I see interrupts around 13k. If I run it with a delay, the interrupts jump to about 45k, regardless of the interval (`vmstat 1` shows 45k interrupts, `vmstat 10` showd 45k interrupts)

I have vmware tools installed.

My suspicion is that my minimal install is missing some critical service, like acpid or cpuspee. This is a samba fileserver, and the only one of four RHEL5 VMs on this host giving this trouble.

Thanks for any advice or links.

Mouse pointer is missing after VMware tools installed

Bones3876 — Mon, 16 Nov 2009 10:30:43 GMT

Might be a bit late but just for info:

If you have issues with the Mouse pointer being missing after VMware tools installed

http://communities.vmware.com/message/419558

Then try installing the vmware tools then using the keyboard navigate to device manager and select:
Mice & Other pointing devices, right click VMware Pointing Device & select properties,
Selected Advanced Settings tab, change Wheel Detaction to disabled.
Click OK and reboot.

This worked for me fine.
