Server 2012 Pulled into Saved State With Server 2008 R2 Host

When the Hyper-V host is a Windows Server 2008 R2 and the VM runs Windows Server 2012, the VM may be pulled into a saved state.

This may be due to the following:

  • The Hyper-V Integration Services version is not up-to-date in VM
  • Backup (Volume Snapshot) Integration Service is disabled or not installed.
  • The virtual machine has one or more dynamic disks.
  • The virtual machine has one or more non-NTFS based volumes.
  • The virtual machine Cluster Resource Group in a cluster setup is offline.
  • The virtual machine is not in a running state.
  • A ShadowStorage assignment of a volume inside the virtual machine is explicitly set to a different volume other than itself.
  • An App-V drive is installed on the virtual machine that creates a non-NTFS volume.

Or you need to apply the following registry fix inside the guest OS:

Crete a key "SystemRestore" and then a value inside of it called ScopeSnapshots:

	HKLM\Software\Microsoft\Windows NT\CurrentVersion\SystemRestore 

	 REG_DWORD ScopeSnapshots 0x00

 

 

We recommend using BackupChain to back up Hyper-V virtual machines from the host or inside the guest OS.
