I just noticed that vSphere has been added to the Windows Server Virtualization Validation Program:
Products that have passed the SVVP requirements for Windows Server 2008 R2 are considered supported on Windows Server 2008, Windows 2000 Server SP4 and Windows Server 2003 SP2 and later Service Packs, both x86 32-bit, and x64 64-bit.
Might come in handy when you need to get support from Microsoft….
One of my customers recently asked if it was possible to change the time-out for a power state change, at the same time this question was asked and answered on an internal mailing list. I thought it would be nice to document it. An example of a power state change task would be the shutdown that is initiated by SRM when you run a recovery plan. The default value is 120 seconds which might not be long enough and could lead to issues when a power off is forced. You can increase or decrease this value by editing the SRM configuration file (vmware-dr.xml). Look for the following section:
<Recovery>
<powerStateChangeTimeout>120</ powerStateChangeTimeout>
</Recovery>
Like stated above, the time-out value is in seconds. The default value is 120 and it can be changed according to your requirements. This change will be effective when the SRM service has been restarted. (If you can’t find this section in the XML file, just add it…)
Yesterday I posted about the article on the hostd, vpxa and vpxd log file options. Today another KB article has been released to setup a rotation scheme for the VM’s log file: vmware.log. Might be worth checking it out and setting it up. You need to change the VM’s vmx file for this to work though. In short:
logging = true or false
log.rotateSize = maximum size in bytes the file can grow to: 10000
log.keepOld = rotation level, amount of log files to keep: 10
log.fileName = change name and path of log file
Over the last couple of months I gathered the following tweaks for a better performance insight the virtual machine, besides disabling / uninstalling useless services and devices:
So if you’ve got an addition, please post it and I’ll keep updating this blog post!
I’m not the only one who thinks that the Storage VMotion interface is a burden. A couple of scripting wizards started creating a decent interface for the Storage VMotion script, which definitely come in handy. Check them out:
