This is most likely due to having clusters at compatibility level 3.5.

So downgrade that one as well to 3.6. You can check also 'yum transaction'
to see how to undo the entire last transaction (assuming it was just to
upgrade the setup packages).

But you only upgraded the setup packages, right? The engine should still
be startable. If it's not, please check/post:
1. rpm -qa | grep ovirt
2. links to engine logs (from /var/log/ovirt-engine)

Best,
