Right now we don't have any pre-live-migration event notification from the NOVA to the NEUTRON, in order for Neutron to take necessary action to pre-emptively deploy the router and the additional hooks.
We need to have a Nova to Neutron handshake on pre-live-migration and when the Neutron notifies the nova with a success message, then nova should migrate.
Otherwise we will be seeing this problem.
