No Hyper-V Machines are Listed in Hyper-V tab
On some servers the Hyper-V tab will be blank with no virtual machines showing up, even though the server has VMs installed and running.
Cause & Resolution
In BackupChain v3, the VM configuration in Hyper-V must be version 6.2 or later. The folder
C:\ProgramData\Microsoft\Windows\Hyper-V\Virtual Machines should contain the vmcx file of the VM machine you want to back up.
Note: only VMs running on that host will show in the Hyper-V VM list for backup.
Note: The C:\ProgramData folder is hidden. To make it visible, change the Windows Explorer settings: Press Alt+T then select View, and uncheck the options 'Hide protected operating system files' and related entries. Also check 'Show hidden files, folders, and drives'.
Then re-open the BackupChain Monitor or click Refresh to get the virtual machines listed in BackupChain.
