From the editors Virtual Desk
Hi everyone, this week’s newsletter comes to you from Las Vegas where I am attending a VMware employee conference. Of course it is also great that this conference is being held in Las Vegas. There are a number of new additions to the newsletter which I will be bringing you starting next week. With the help of my TAM colleague Paul and some of the wonderful folk at VMware who are always sending us useful information we have included much of this in the newsletter this week. Of course we have only included news that is of public interest but due to the source of this we feel that it is a great addition to our newsletter and we will try and include this type of information as often as possible.
To all of my TAM customers I look forward to seeing all of you next week when I am back and hopefully talking to you about some of the exciting new technologies that we will be bringing to the world of virtualization in the near future.
Have a fantastic week everyone.

Are you thinking about implementing jumbo frames with your IP storage based vSphere infrastructure? Have you asked yourself why or thought about the guaranteed benefits? Various credible sources discuss it (here’s a primer). Some will highlight jumbo frames as a best practice but the majority of what I’ve seen and heard talk about the potential advantages of jumbo frames and what the technology might do to make your infrastructure more efficient. But be careful to not interpret that as an order of magnitude increase in performance for IP based storage. In almost all cases, that’s not what is being conveyed, or at least, that shouldn’t be the intent. Think beyond SPEED NOM NOM NOM. Think efficiency and reduced resource utilization which lends itself to driving down overall latency. There are a few stakeholders when considering jumbo frames. In no particular order:
ESX Virtualization 24/01/11 10:35 PM Vladan SEGET Free Stuff PowerGui scripting VMware VMware Power Pack
Vesi and PowerGUI will become one tool. In fact the efforts are made to maintain unique platform only and merge those 2 projects.
What now? Many vSphere administrators now still have the possibility to use PowerGUI which is another graphical user interface which can be used to run, create and test new scripts. Very popular VMware Power Pack can be used with PowerGUI. Dimitry Sotnikov who is the person in charge of PowerGui, and I already reported about this tool here and here, has informed about why the process of merging those 2 projects.
It’s an unique free tool which is helpful not only for vSphere environments, but there are also PowerPacks for Hyper-V, Active Directory, Exchange Server and others…. See how the PowerGUI can help you with daily tasks of maintenance, reporting etc….

RVTools is a windows .NET 2.0 application which uses the VI SDK to display information about your virtual machines and ESX hosts. Interacting with VirtualCenter 2.5, ESX 3.5, ESX3i, ESX4i and vSphere 4 RVTools is able to list information about cpu, memory, disks, nics, cd-rom, floppy drives, snapshots, VMware tools, ESX hosts, nics, datastores, service console, VM Kernel, switches, ports and health checks. With RVTools you can disconnect the cd-rom or floppy drives from the virtual machines and RVTools is able to list the current version of the VMware Tools installed inside each virtual machine. and update them to the latest version.

With virtualization come management challenges. Now that applications compete for shared, dynamic infrastructure resources such as storage, memory, and CPU, an inevitable resource allocation problem arises, that if not addressed will impact the performance of both VMs and their associated applications. This presentation discusses the 20 metrics that truly matter in vCenter to evaluate and manage this situation.

I’ll admit I haven’t had to install APC’s PowerChute Network Shutdown product on my ESX(i) hosts lately, as the kind of DCs I’m hosting stuff in doesn’t cater for the UPS in a rack scenario. That said, I’ve had the (mis)fortune to have to install and configure this software in years gone by. As luck would have it, VMware published a KB articlerecently that points to APC’s support website for information on the how and what. There are two PDF files on the APC support page – one for ESX and one for ESXi. So, if you’re into that kind of thing, then you should find this useful.

We’ve covered snapshots here a few separate times in past. However most of these were focused on ESX classic or preforming the work using one API or another. As VMware is making the shift to ESXi, it makes sense that you will need a way to deal with snapshots from the ESXi console (aka TSM/Tech Support Mode).

This little missive concerns other functionality of SRM which we may see in the future… It’s much more general than the 1st part which focused on VMware’s HBR (Host Based Replication) technology. You can see some tantalizing hints at the future direction of SRM such as being a tool facilatate site migrations, perhaps even been used as engine to move VMs into the cloud. I also take a peek at some of improvements in re-IPing virtual machines, and VM Groups.

I recently deployed some new hardware in my lab and to my surprise discovered that after moving several VMs to the new hosts their memory utilization went up. I also noticed that Transparent Page Sharing (TPS) wasn’t working on these hosts. This didn’t make sense so naturally I did some digging and I want to share with you what I’ve learned as I know I’m not the only one upgrading hardware and many of you will likely stumble onto this same issue.

Standardize new virtual machine provisioning with templates
It’s been a pain to create new virtual machines with the right software installed and configured properly. You can always use tools like KickStart to automatically install the operating system and then install other software as needed. But configuring such an environment is not trivial, and it takes a long time from start to finish.
With the rise of virtualization, more virtual machines are provisioned (and decommissioned) than ever before. Installing each new virtual machine from scratch is not the ideal solution.
While virtualization highlights the provisioning problem, it also offers an easy solution. It’s called a virtual machine template. You can pick and configure every piece of software you will need into a template, and clone it to new instances whenever needed. It’s not only easier but also much faster.

Within the virtualization community we have been seeing more and more people adopting ESXi. Not only adopting it but also actively evangelizing the use of ESXi over ESX classic. The main argument being of course the reduction in operational effort involved with maintaining the platform. Last week two excellent articles were published. The first article was by Bob Plankers of LoneSysAdmin.net fame. Bob wrote an excellent article countering all often heard complaints about ESXi.

For the past 6 months we have been working on a joint project. It has actually been kept pretty quiet, and it is now time to make this public.
Previous VMware vSphere books have focused on how to master the technology, deep-diving into certain elements and giving tips & tricks that help you manage your virtual infrastructure.
But we felt there was something missing in all these books. What was missing was how to design an infrastructure, accounting for all the elements that you need to consider. For example:
vFAIL.NET 27/01/11 10:19 PM Sean Crookston VMware view KMS MAK VMware View
Recently I was setting up a VMware View in my home lab and came across this error, which I had seen before. The error occurs because a KMS server is not properly setup to activate the Windows 7 linked clones. As result I could not access any of the linked clones I created .
I don’t need these machines for any reason other then to play around with different options for linked clone pools so I began looking for a work around to this issue and found one here. In the base image you created, you would have installed the VMware View Agent. On that system you will find two registry keys of interest that you may want to modify. As stated, this is not supported by VMware but may be good for proof of concept or demo purposes as getting a KMS server can sometimes be difficult to get set up in certain

I recently have received a couple of questions regarding how long it takes to get the VCAP-DCA and a while back someone even asked how long the whole process to become a VCDX might take.
The purpose of this blog entry is not to answer the question but to discuss what it takes for each step, although I will try and explain what time I have taken on the steps I have completed thus far. I have an idea in my mind when I would like to do certain parts of the path but the true answer will depend on when I feel I am ready. For purposes of simplicity and the fact the VCDX3 has only one last defense possibility(I believe), this will focus strictly on those who are not a VCDX 3 already and are pursuing the VCDX 4. As I have only gotten as far as getting my VCAP-DCA, I hope to update the latter part of this entry with more of my experiences.

It took a while, but finally here it is the VCDX 4 program. Now some of us who were fortunate enough to complete the VCDX 3 certification and managed to pass VCAP-DCD are already a VCDX 4, but for those of you who just started the journey now is the time to start digging!
In general the process hasn’t really changed all that much:

I downloaded many appliances and hoped to have all of them up and running in a bare minimum amount of time. Apparently I miscalculated / underestimated the amount of work to get a virtual appliance up and running. Yes of course there are a whole bunch that will work out of the box, and all of these have one thing in common:

I often get asked for advice on tuning the DRS migration threshold, and my standard answer is to stick with the default. However, I can appreciate that when you provide a nice looking slide bar with five possible settings there is a natural tendency to want to change things, and trying to convince people to resist this urge requires a bit more than a simple “stick with the default”. So let me explain why, in most situations, keeping the default migration really makes sense.

Despite our best efforts here at VMware, there are occasions where a PSOD may occur. PSODs can occur for a wide range of reasons, including out of memory and hung CPU conditions. In a HA protected environment, if a PSOD does occur you would expect that the VMs that were running on the host that encountered the PSOD would be failed over to another host. There does exist a corner case where this may not be the case. Let me explain why:
