Public bug reported: I am using nova ( version 2.17.0 ) on a compute node and there is a server running the controller node
when i try to launch an instance when the nova compute is up, this is stuck on scheduling state (building task) and i see this error on the nova-comute.log on the compute node: 2015-11-15 13:36:29.250 9650 ERROR object [req-df2b305b-34b4-4022-9102-bed250495718 3f6b0a08e0d74d5f82c240d8a7860404 26cc6b29f6b24c5ebff8131f306602cc] Unable to instantiate unregistered object type NetworkRequestList 2015-11-15 13:36:29.250 9650 ERROR oslo.messaging.rpc.dispatcher [-] Exception during message handling: Unsupported object type NetworkRequestList 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher Traceback (most recent call last): 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 133, in _dispatch_and_reply 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher incoming.message)) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 176, in _dispatch 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher return self._do_dispatch(endpoint, method, ctxt, args) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 121, in _do_dispatch 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher new_args[argname] = self.serializer.deserialize_entity(ctxt, arg) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/nova/rpc.py", line 111, in deserialize_entity 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher return self._base.deserialize_entity(context, entity) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 575, in deserialize_entity 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher entity = self._process_object(context, entity) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 542, in _process_object 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher objinst = NovaObject.obj_from_primitive(objprim, context=context) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 251, in obj_from_primitive 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher objclass = cls.obj_class_from_name(objname, objver) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 201, in obj_class_from_name 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher raise exception.UnsupportedObjectError(objtype=objname) 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher UnsupportedObjectError: Unsupported object type NetworkRequestList 2015-11-15 13:36:29.250 9650 TRACE oslo.messaging.rpc.dispatcher 2015-11-15 13:36:29.251 9650 ERROR oslo.messaging._drivers.common [-] Returning exception Unsupported object type NetworkRequestList to caller 2015-11-15 13:36:29.251 9650 ERROR oslo.messaging._drivers.common [-] ['Traceback (most recent call last):\n', ' File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 133, in _dispatch_and_reply\n incoming.message))\n', ' File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 176, in _dispatch\n return self._do_dispatch(endpoint, method, ctxt, args)\n', ' File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 121, in _do_dispatch\n new_args[argname] = self.serializer.deserialize_entity(ctxt, arg)\n', ' File "/usr/lib/python2.7/dist-packages/nova/rpc.py", line 111, in deserialize_entity\n return self._base.deserialize_entity(context, entity)\n', ' File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 575, in deserialize_entity\n entity = self._process_object(context, entity)\n', ' File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 542, in _process_object\n obji nst = NovaObject.obj_from_primitive(objprim, context=context)\n', ' File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 251, in obj_from_primitive\n objclass = cls.obj_class_from_name(objname, objver)\n', ' File "/usr/lib/python2.7/dist-packages/nova/objects/base.py", line 201, in obj_class_from_name\n raise exception.UnsupportedObjectError(objtype=objname)\n', 'UnsupportedObjectError: Unsupported object type NetworkRequestList\n'] i see that my nova/objects/__init__.py is this: # Copyright 2013 IBM Corp. # # Licensed under the Apache License, Version 2.0 (the "License"); you may # not use this file except in compliance with the License.
