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
