Hello I am running Server 2008 R2 with a handful of Hyper-V guest nodes. If Windows backup runs without any of the Hyper-V nodes running, the server is fine. If Hyper-V runs a backup while the Hyper-V nodes are running, it is fine until a few minutes after the backup completes, and then it BSODs. The storage location for the backup is iSCSI - I am wondering if anyone has any input on what might be causing this? I don't have the Hyper-V nodes setup on a vlan and there is only one NIC on the server. Is it possible this is a networking / driver issue, and if so how would I reconfigure the networking to fix this?

Can you provide some specifics on the BSOD?– ErnieTheGeekJun 25, 2012 at 13:45

What is your version of volsnap.sys? This is probably fixed in the most recent hotfix.
"0x0000007E" or "0x00000050" Stop error when you create snapshots of a volume in Windows Server 2008 R2 or in Windows 7

"0x0000007E" Stop error when you run a VSS-based backup application in Windows 7 or in Windows Server 2008 R2
http://support.microsoft.com/kb/2548124
But don't use those hotfixes. Use the most recent version 6.1.7601.21854 of volsnap.sys availble here:
Stop error when you create a VSS snapshot backup in Windows 7 SP1 or in Windows Server 2008 R2 SP1: "fvevol!FveFilterDeviceControl+1d0"

or here:

Thanks this looks promising, my version of volsnap.sys is not the current one - I have to wait until the weekend to test this though but I'll update. Jun 26, 2012 at 13:20
