VM won't migrate to other host after failed backup.

thedobe

My VM's had issues with backups and won't complete a back up. That's one problem. The other problem is that I can't migrate the VMS between hosts live. I think the disks are in some locked state. My guess is that one is feeding into the other. Any advice on how to unlock the disks/remove the metadata tag that tells XO that they are locked in a backup process (even though none are running)? Thanks.

@thedobe Have you checked the VM's Advanced tab to make sure the Prevent migration option is disabled?

@Danp Thanks... Just ticked that off and they are migrating. I'll try backup again but something tells me the backup issue will still persist. I'll send logs once that fails.
