ovirt-engine-4.4.8.1-0.9.el8ev.noarch
Verification steps:
1. I Created a VM with a raw disk (via UI - thin provisioned disk on NFS SD)
2. Validated that the disk I created is RAW using API call - <{{engine}}/disks/6b816761-c10d-4831-98dc-72c4491b01cb>
3. Created 3 snapshots.
4. ran full backup using[1]
$ python3 backup_vm.py -c engine full <vm-id>
5. Previewed the second snapshot.
6. Committed the second snapshot.
Verification conclusions:
The expected output matched the actual output.
The total flow mentioned was done with no errors.
The VM snapshot of the RAW disk was restored successfully after the commit - <Restoring VM Snapshot snap2 of VM test1059 was completed successfully>
Bug verified.
