I have errors when live migrating that started after I installed a new NIC in one host. Live migrate was working fine before the changes. The vdsm log shows the errors below depending on if i am migrating from host1 or host2. Running ovs-vsctl list-br shows that the bridge exists. Ip a shows the interface is down. I do not know what a vdsm bridge is for or if the server just needs to restart a service to get things in order again.
