I'm running some tests in a 4.1 testenvironment.
At the moment testing on a Oracle Linux 7.3 VM

- using oVirtBackup from master (version is on 3rd of July 2016)

$ ./backup.py -c config_test.cfg
Mar 08 17:37:08: Start backup for: Oracle7
Mar 08 17:37:09: Snapshot creation started ...
Mar 08 17:38:23: Snapshot created
Mar 08 17:38:33: Clone into VM started ...
Mar 08 17:40:31: Cloning finished
Mar 08 17:40:32: Snapshot deletion started ...
Mar 08 17:41:53: Snapshots deleted
Mar 08 17:41:54: Export started ...
Mar 08 17:43:56: Exporting finished
Mar 08 17:43:57: Delete cloned VM started ...
Mar 08 17:44:01: Cloned VM deleted
Mar 08 17:44:01: Duration: 6:54 minutes
Mar 08 17:44:01: VM exported as Oracle7_BACKUP_20170308_173708
Mar 08 17:44:01: Backup done for: Oracle7
Mar 08 17:44:01: All backups done

NOTE: during the snapshot creation I see in web admin console the VM in
paused state and also not responsive in both console and ssh session.
After a couple of seconds it comes back and as a confirmation I see this in
its messages:

Mar  8 17:38:57 T-ORACLE73 chronyd[616]: System clock wrong by 19.077230
seconds, adjustment started

Is this expected?

Not yet used the vm_backup.py, I;m trying to get sdk4 on Fedora 25 before
(see the other thread I opened)...
