Hi, I have several Windows 2012 VM's running on a 2012 R2 host. None of these VM's can do an online backup. They both have a SCSI controller installed, and all the HyperV integration services installed. For a 2008 R2 HyperV host, theHKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SystemRestore\ScopedSnapshots registry entry needed to be added.
Does this also need to be added when 2012 R2 is the host?
