I'd like to ask for a freeze exception for the follow bug fix:


bug: *https://bugs.launchpad.net/nova/+bug/1444497

merged bug fix in master: *https://review.openstack.org/#/c/173913/

During live migration _post_live_migration and
post_live_migration_at_destination_method are executed simultaneously,
because second one is called over rpc.cast.
In _post_live_migration method there was setup_network_on_host call
with teardown=True, which expects new host in instances table db

This update could be happened later, as it executes on destination
node in second method. To guarantee execution order
setup_network_on_host call, which cleans
dhcp-hostfile is moved to destination node.
