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.

Ales

[ovirt-users] Re: New host: no network interfaces visible

2020-10-22 Thread Richard Chan 
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.

Regards
Richard Chan

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
