Hi,

I’m looking at rollback_live_migration_at_destination() in
compute/manager.py. If it’s shared storage (such as NFS,
is_shared_instance_path is True), it’s not going to be called since
_live_migration_cleanup_flags() will return False. Can anyone let me
know what’s the reason behind it? So nothing needs to be cleaned up at
the destination in such case? Should VIFs be unplugged, to say the least?

I’m working on the live migration support with SR-IOV macvtap
interfaces. The devices allocated at the destination needs to be freed.

thanks,
Robert
