Hi, I have a new Openstack cloud running in our lab, but I am unable to launch instances. This is Ocata running on Ubuntu 16.04.2 Here are the errors I am getting when trying to launch an instance: On my controller node in log file /var/log/nova/nova-conductor.log 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager [req-a9beeb33-9454-47a2-96e2-908d5b1e4c46 b07949d8ae7144049851c7abb39ac6db 4fd0307bf4b74c5a8718b180c24c7cff - - -] Failed to schedule instances 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager Traceback (most recent call last): 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/conductor/manager.py", line 866, in schedule_and_build_instances 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager request_specs[0].to_legacy_filter_properties_dict()) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/conductor/manager.py", line 597, in _schedule_instances 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager hosts = self.scheduler_client.select_destinations(context, spec_obj) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/scheduler/utils.py", line 371, in wrapped 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager return func(*args, **kwargs) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/scheduler/client/__init__.py", line 51, in select_destinations 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager return self.queryclient.select_destinations(context, spec_obj) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/scheduler/client/__init__.py", line 37, in __run_method 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager return getattr(self.instance, __name)(*args, **kwargs) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/scheduler/client/query.py", line 32, in select_destinations 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager return self.scheduler_rpcapi.select_destinations(context, spec_obj) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/nova/scheduler/rpcapi.py", line 129, in select_destinations 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager return cctxt.call(ctxt, 'select_destinations', **msg_args) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/oslo_messaging/rpc/client.py", line 169, in call 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager retry=self.retry) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/oslo_messaging/transport.py", line 97, in _send 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager timeout=timeout, retry=retry) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/oslo_messaging/_drivers/amqpdriver.py", line 458, in send 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager retry=retry) 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager File "/usr/lib/python2.7/dist-packages/oslo_messaging/_drivers/amqpdriver.py", line 449, in _send 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager raise result 2017-05-17 16:48:33.656 2654 ERROR nova.conductor.manager NoValidHost_Remote: No valid host was found.
