Comment 1 Avihai 2021-07-04 09:16:15 UTC 
The issue is fixed but the fix patch is only in master(upstream) but not in current RHV 4.4.7-6 (which is 4.4.7 RC/ python3-ovirt-engine-sdk4-4.4.13-1)
@Eyal can someone assist as this is breaking a lot of Tier2 automation test cases and considered automation blocker for QE.
