Problem Statement:

I am getting an error, that is causing the hyperV to be unstable. I have 3 hyperV servers in my test env, runnning about 45 clients. All 3 are reporting this error at some point through the day. This often means that I need to restart the service hyperV Virtual Machine manager, and obviously during that time the SCVMM server (which is a VM client within these 3) looses contact until the service is restarted.

Answer:

The problem is a known bug and is fixed in Windows 2008 SP2.
The problem is due to having a virtual machine configured with a SCSI adapter that does not have a drive attached to it. I had virtual machines with this configuration. since removing the un used SCSI adapter, my Hyper V service does not stop and restart.
So go thru each VM and remove any SCSI adapters that does not have a drive associated with it.
Hope this helps you guys.
Thanks
