Would you provide more information (logs, screenshots) about the pains
of installing ovirt-3.6? These days, most of the development effort is
focused on stabilizing 3.6. No further releases of ovirt-3.5.z are
expected (up to horrible security bugs, etc), so we advise using 3.6 in
new instllations.

ovirtmgmt should have been automatically added on top of the interface
that has the IP used to add the host to Engine.

Could you share your engine.log and {super,}vdsm.log from that time to
understand why did it happen?

Similarly, please share your ifcfg files prior to adding ovirtmgmt, and
the supervdsm logs that end up with disconnection.
