Hi Ales, the problem was resolved by starting NetworkManager.
Previously our workflow had always been to disable firewalld, and NetworkManager.
Is it the case that newer ovirt 4.3.x uses NetworkManager to enumerate physical devices?
What resolved the situation: create a single ethernet NIC (no ovirtmgmt bridge) for the management VLAN with NetworkManager
running - connect to engine - suddenly all the physical NICs were visible in oVirt and it took over. It created the ovirtmgmt bridge consuming the original NIC card, and I could proceed with the rest of the networks. It also moved all the network devices to the NM_CONTROLLED=no state.
What was most unexpected in 4.3.10 (w/ a fresh host) was that NetworkManager was needed to "bootstrap" the host.
