Restore & Attach Issue
I do not receive any error, everything looks as expected the backup is used to
create a volume on the primary storage and it is attached to the instance
(running or stopped). I initially noticed that the attached disk had no
partition table, and when I looked at start of the device (vdb) I could see
it was actually a qcow2 label seen from within the guest.
This is what is seen on the hypervisor, which is Ubuntu 24.04.2 LTS.

View from within the guest, see the actual qcow2.

When I look in the volumes table I see its format is NULL.
