No, you should only plug the network to oVirt but not configure any ip
on the hypervisors.

No, you don't need. I've only management on engine host. The
hypervisors, instead have an ip on management and storage network, and
no ip on the other networks. For bmc traffic we use routed access
through a firewall that is dividing bmc network from the rest of the
world.
