Fixed In Version: python-os-vif-1.4.1-2.el7ost
Doc Type: Bug Fix
Doc Text:
At some point during a live-migration, the source and destination bridges can be on the same L2 and we could have the destination bridge learning from the source bridge. To prevent this, configure the linux bridge installed for the particular vif type 'ovs-hybrid' to persistently keep the MAC learned from the RARP packets sent by QEMU when starting on destination node. This avoids any break of the datapath during a live-migration.
