Why do you think so? There is no such package. It should have simply
gave an error message. Did you mean 'yum upgrade ovirt-engine-setup'?
This is fine.

Before starting such an upgrade, you should set hosted-engine maintenance
to global. Please see [1]. Otherwise, when engine-setup takes down the
engine, the ha daemons consider this a problem and after some time try
to migrate the machine. At this point, what do you get from:
hosted-engine --vm-status
on the hosts?

Even though you should have set global maint, not sure this is expected.
Was the engine VM rebooted (check uptime)?

If gloabl maint isn't enough, please post somewhere all relevant logs -

from engine:
/var/log/ovirt-engine (especially engine/server.log and setup/*)
/var/log/messages

from hosts:
/var/log/ovirt-hosted-engine-ha/*
/var/log/vdsm/vdsm.log

If the engine vm did stay up, but the screen session died, I can't think
of many reasons for that - perhaps OOM? How much ram does it have? Note
that engine+dwh+reports need considerably more ram than the engine alone.

Best,
