Public bug reported: When live migrating network sensitive VMs, the communication is broken.
This is similar to [1] but in OVN the vif-plugged events are directly controller by the Neutron server, not by the OVS/DHCP agents. The problem lies in when the destination chassis creates the needed OF rules for the destination VM port. Same as in OVS, the VM port is created when the instance is unpaused. At this moment the VM continues sending packets through the interface but OVN didn't finish the configuration.
