Just adding a few things I noticed during testing, on top of what Fabian
already mentioned:
1. VM data not wiped after deletion:
When I delete a VM and then create a new one with the same settings, the
old OS and data are still there. It looks like the disk wasn't properly
cleaned up.
2. Can’t roll back to older snapshots:
Rolling back only works for the latest snapshot. If I try to go back to
an earlier one, I get this error:
TASK ERROR: can't rollback, 'test01' is not most recent snapshot on
'vm-104-disk-0.qcow2'
3. Rollback doesn't work for LVM-thin volumes:
When trying to roll back a snapshot on an LVM-thin volume, it fails with:
can't rollback snapshot for 'raw' volume
