(Get the code!)
by the way nova does not tear down any networking on the source node until post_live migration and it does not activate the dest port bidnign until post live migration either so nova intentiolly leave the source node fully intack until post live migration so that on revert or errors in pre_live migration no reconfirutation is needed on the source node and i can simple delete the inactive port binding on the dest node.
so in a rollback case nova should not need to do any rebinding of the port on the source node.
