I am seeing an issue with a few VMs where if you turn the VM off from within the guest OS, the status does not change in the VMM console.
Details about the environment:
- Six node cluster running Server 2012 R2 Datacenter Core
- Cluster validate completed successfully. Only warnings due to some VMs being offline
- Virtual Machine Manager 2012 R2 with UR2
- 251 VMs in cluster used for Citrix XenDesktop and XenApp
I've read a few articles similar to this one that refer to a change in the VM Light Refresher schedule from RTM to SP1. (http://blogs.technet.com/b/chengw/archive/2012/09/17/update-on-vmm-refreshers-what-has-changed-and-what-this-means-to-you.aspx).
Basically it looks like the light VM refresher was turned off and now we depend upon WMI if the environment support WCF 3.0.
Does this mean that we're looking at the WMI on the Host or the Guest? Or, is it possible that I just have WMI corruption in a few guest VMs?
If I want to turn it back on, it seems like I should be able to create a registry DWORD key in HKLM\SOFTWARE\Microsoft\Microsoft System Center Virtual Machine Manager\Settings called VMPropertiesUpdateInterval and set the value. Does this seem plausible?
Would it be supported?
