  in nova/compute/manager.py class _ComputeV4Proxy has method:
  def check_can_live_migrate_destination(self, ctxt, instance, destination,
                                             block_migration, disk_over_commit):
          return self.manager.check_can_live_migrate_destination(
              ctxt, instance, destination, block_migration, disk_over_commit)

  here is signature of ComputeManager's class method:
   def check_can_live_migrate_destination(self, ctxt, instance,
                                             block_migration, disk_over_commit):

  There is no 'destination' param in it. It should be removed from
  rpcapi, or added to implementation. _ComputeV4Proxy was added by patch
