| Doc Text: |
Originally, if an instance was migrated to a new location, the connection to the instance was broken, although the instance was successfully spawned in the new location. The connection was recreated after the original connection timed out. To workaround this issue, the linux bridge installed for the particular VIF type `ovs-hybrid` should be configured to persistently retain the MAC address learned from the RARP packets that are sent by QEMU (after starting on the destination node). This will avoid any disruption of the data-path during a live migration, since at some point during the process the live migration source and destination can be on the same L2 network, and could have the destination bridge learning from the source.
