Description
Snapshot metadata should be removed after disk was detached from VM.
If snapshots metadata is not removed and some other disk is attached to VM, you cannot create new snapshots, because they already exist in virus domain object.
virsh snapshot-list --domain one-7589
delete all
virsh snapshot-delete one-7589 {disk_id}-{starting_snapshot_id} --metadata --children
ex.: virsh snapshot-delete one-7589 2-0 --metadata --children
starting_snapshot_id can be > 0, if disk with existing snapshots was attached and some new snapshots was created, so we need to check if before deleting.

This also prevents VM's with a DISK Snapshot (not DOMAIN snapshot) from being live migrated through ONE to other hosts (as it's seen as a DOMAIN snapshot). Recently found out about this when doing host maintenance (some VM's could not be live migrated :/).

I can confirm what Stefan said. I also have this experience.
