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.

Glad to hear that the problem was resolved.

4.3 should work fine without NetworkManager being involved. As you have pointed out we are actually
disabling NM access to the configuration after vdsm takes over the device.

On the other hand oVirt 4.4 is a different story, it needs to have NM running, just you are aware if you decide to test oVirt 4.4.

Regards,
Ales

What could cause no Network Interfaces visible in installing a new host?

I have added a new host to oVirt 4.3.10, the initial SSH installs all the packages (all with failed=0 in host-deploy/*log). The installation is shown as failed without any meaningful message.

However the Network Interfaces page is blank, what could cause this?

Host in CentOS 7.8 tried with/without biosdevname.

Hello Richard,

can you please share relevant logs from the host deploy?
It should be located on the engine machine /var/log/ovirt-engine/host-deploy/.

Thanks.

Regards,
Ales Musil
