It only needs a simple script to poke the correct value, and that could be easily integrated into vendor scripts. The general idea of being able to have a callback to userspace is okay but we'd like something lighter weight for live migration, which is typically done only within the scope of a single layer-2 network and hence all that is really required is the gratuitous ARP to kick the switch hardware. -- Keir
