Hi Marcel,
Before ovirt-engine-4.3.3.2, the 4.3 compatibility version was considered as V4, and from that version, it was considered as V5.
Therefore, it seems that since your Default DC was created before that version, it was considered as V4.

You can try to make it V5 by doing the following:
- Edit the Default cluster, re-choose the 4.3 option on the 'Compatibility Version' field and press OK.
- Do the same for the Default Data Center.

I believe that your newer engine, which considers 4.3 as V5 format, will do the relevant update on your environment.

Regards,
Shani Leviim

Hi Shani,

on the productive cluster (Default) the compat level is 4.3 and on the cluster
it's 4.3 too so I can't raise the level to update the format to V5.

I added some screenshots.

Regards

Marcel
