vmware - How to WaitForUpdates from VMs in a cluster? -

i using vmware vsphere ws sdk in python using suds client. want wait changes vms. interested in vms of particular cluster. there way in propertyfilterspec that? tried setting managed object reference of cluster in objectspec no avail. like:

object_spec = client_factory.create('ns0:objectspec') object_spec.obj = cluster_mor object_spec.skip = false 

figured out myself. had set proper traversal spec also:

object_spec = client_factory.create('ns0:objectspec') object_spec.obj = cluster_mor object_spec.skip = false object_spec.selectset = build_recursive_traversal_spec(client_factory)  def
