But it appears to still be working. At least I've not noticed links being down, and "ifconfig" shows decent amount of traffic on both eno1 and eno2.
Maybe wipe, re-install, configure it manually, and then install ovirt? -derek On Thu, April 20, 2017 8:58 pm, Bryan Sockel wrote:

I am pretty sure it is related to the bridge that was created to pass vm-host-altn traffic when the appliance was first installed.

Are you sure the switch side is all the same LACP group? Sounds like one port may accidentally be in a separate group, and that happens to be em1.
You might try swapping wires between em1 and another port and reboot and see which ports come up - if all but the port with the wire formerly in em1 come up, it points to the switch config.
