Changing gateway and hostname of the Service Console ESX 3.X

cfo — Mon, 25 Aug 2008 12:57:00 GMT

These settings can be changed using the Virtual Infrastructure Client or from the physical or a remote console connection (ILO, RSA, DRAC, etc)

From the Virtual Infrastructure Client

1.Highlight the ESX Server host and click on the Configuration tab
2.Click on DNS and Routing
3.Click on Properties...
4.To change the hostname, domain, and DNS servers, click on the DNS Configuration tab and enter the appropriate values
5.To change the default gateway, click on the Routing tab and enter the appropriate values

Note: Hostname and domain changes through the Virtual Infrastructure Client do not take place until the ESX host is rebooted.

From the physical or remote console connection

Edit the /etc/hosts file with an editor and modify it so that it reflects the proper IP address and hostname.

To change the default gateway address and the hostname for the Service Console edit the /etc/sysconfig/network file and change the GATEWAY and HOSTNAME parameters to the proper values.

After you edit these files, you must reboot the host or restart the network service using the following command:

--root@server root--# service network restart

Note: This command will break any current network connections to the service console.

You can also dynamically change the hostname using the command:

--root@server root--# hostname newname

Note: This command creates a temporary hostname change. This change is lost when the system is rebooted.

To change the DNS server settings, edit the /etc/resolv.conf file, update the nameserver IPs, and search domain if applicable.

Verifying ESX Server host networking configuration on the service console

Acrobat Reader 5.0 Won't Run in a Virtual Machine

How can I set a static MAC address for Virtual Machine

cfo — Wed, 20 Aug 2008 11:06:00 GMT

Editing the VMX file of the VM
Edit the VMX file of the VM
Change the following line from ethernetN.addressType="vpx" to ethernetN.addressType="static" (N is the number of your ethernet adapter, usually 0)
Next change the line "ethernetN.GeneratedAddress" to "ethernetN.address" and then change the current MAC address to "00:50:56:XX:YY:ZZ" (again N is the number of your ethernet adapter and XX is a valid hex number between 00 and 3F, and YY and ZZ are valid hex numbers between 00 and FF. The value for XX must not be greater than 3F in order to avoid conflict with MAC addresses that are generated by the VMware Workstation and VMware GSX Server products.)
Power your VM back on. Login to the OS, go to the CMD prompt and type "ipconfig /all", your manually assigned MAC address should be listed for the NIC that you changed

Setting the NIC properties in Windows

Edit the Local Area Connection propeties for the NIC you want to change
Click the Configure button next to the NIC name
On the Advanced tab select NetworkAddress
In the Value field enter a new value for the MAC address, enter only numbers or letters, no spaces, dashes or colons. This MAC address can be any valid hex numbers between 00 and FF for any of the octets
Click OK and that's it, the new MAC address takes effect immediately and will override any MAC address set by Vmware

How can I kill a stuck virtual machine?

cfo — Thu, 14 Aug 2008 11:50:00 GMT

Login to the service console
Type "vmware-cmd -l" to get a list of all VM's and there paths
You can check the VM state by typing "vmware-cmd //server.vmx getstate"
To forcibly stop type vmware-cmd //server.vmx stop hard"
Check VM state again, it should now be off
Type "vmware-cmd //server.vmx start" to power on VM

How to change password on ESX server

cfo — Thu, 14 Aug 2008 11:41:00 GMT

1. Use Virtual Center to Vmotion all of the VMs to other ESX hosts. (if you have a stand alone host then power down all your VMs)
2. Put the host in Maintenance Mode
3. Reboot your ESX host.
4. Physically go to the ESX console. You will not be able to use a remote console like WinSCP for the next few steps.
5. At the first menu type "a"
6. At the next prompt type "single"
7. After ESX finishes booting you will end up at a # prompt
8. Type "passwd" and enter a new password
9. re-type the new password again when prompted
10. Reboot the ESX server normally. ( just type "reboot" at the # prompt)
11. Don't forget to take the host out of Maintenance Mode in Virtual Center.

How to change Virtual Machine name with service console

cfo — Wed, 13 Aug 2008 16:06:00 GMT

There might come a time that you might need to rename a vmdk. How would you go about doing this via the service console?
Scenario: You have vm01 located at /vmfs/volumes/VMFS01/vm01 and need to rename it to web01 and move it to /vmfs/volumes/VMFS01/web01
Steps
1. Power off vm01
2. Right-click vm01 in VIC and remove it from inventory
Note: you could also run
vmware-cmd -s unregister /vmfs/volumes/VMFS01/vm01/vm01.vmx
from the service console
3. SSH to your host, logging in with a non-root account
4. SU to root using, su -
5. Enter
mv /vmfs/volumes/VMFS01/vm01 /vmfs/volumes/VMFS01/web01
This will move your vmdk, vmx, vmsd, vmxf, and nvram files to the new directory
6. cd to /vmfs/volumes/VMFS01/web01
7. Enter
vmkfstools -E vm01.vmdk web01.vmdk
-E correctly renames the virutal disk, -renamevirtualdisk could also be used
This command renames the .vmdk, flat.vmdk, and updates the .vmdk pointer
8. Using vi, modify the .vmx and .vmxf, files to show the new VM name
9. Register the new virtual machine using the following command:

vmware-cmd -s register /vmfs/volumes/VMFS01/web01/web01.vmx
You should see register(/vmfs/volumes/VMFS01/web01/web01.vmx) = 1 if the command was correctly entered.
If you logon to VIC, you will now see the updated VM in your inventory.
