[ovirt-users] Unable to add Hosts to Cluster

Sat Feb 17 12:20:04 UTC 2018

For a proper upgrade there are specific steps that you follow for each host
and the engine.

I usually upgrade the hosts first then the engine. If you have spare
resources so as to put hosts at maintenance then the upgrade should be
seamless. Also i think you need to go strp by step: 3.5 -> 3.6 -> 4.0 ...
etc

In case you have a similar test setup you may try it first there.
