2017-05-15 05:44:59 -0500 asked a question Instance can not be launched from the image


I tried to launch an instance from the Fedora image following the RDO site. However, the instance can not be launched with the following error messages.

File "/usr/lib/python2.7/site-packages/nova/conductor/", line 866, in schedule_and_build_instances request_specs[0].to_legacy_filter_properties_dict()) File "/usr/lib/python2.7/site-packages/nova/conductor/", line 597, in _schedule_instances hosts = self.scheduler_client.select_destinations(context, spec_obj) File "/usr/lib/python2.7/site-packages/nova/scheduler/", line 371, in wrapped return func(*args, **kwargs) File "/usr/lib/python2.7/site-packages/nova/scheduler/client/", line 51, in select_destinations return self.queryclient.select_destinations(context, spec_obj) File "/usr/lib/python2.7/site-packages/nova/scheduler/client/", line 37, in __run_method return getattr(self.instance, __name)(*args, **kwargs) File "/usr/lib/python2.7/site-packages/nova/scheduler/client/", line 32, in select_destinations return self.scheduler_rpcapi.select_destinations(context, spec_obj) File "/usr/lib/python2.7/site-packages/nova/scheduler/", line 129, in select_destinations return, 'select_destinations', **msg_args) File "/usr/lib/python2.7/site-packages/oslo_messaging/rpc/", line 169, in call retry=self.retry) File "/usr/lib/python2.7/site-packages/oslo_messaging/", line 97, in _send timeout=timeout, retry=retry) File "/usr/lib/python2.7/site-packages/oslo_messaging/_drivers/", line 458, in send retry=retry) File "/usr/lib/python2.7/site-packages/oslo_messaging/_drivers/", line 449, in _send raise result

What should I need to do? Do I need to update python or install some packages?

Kind regards,

I'm trying to create and launch an instance from the Linux image. I saw this step in the website below (

Step 3: Create or import a key pair

In the left-side navigation menu, click Access & Security under the heading Compute. In the main portion of the screen, click the tab labeled Key Pairs, and choose either to Create Key Pair or Import Key Pair. The Create Key Pair dialog will prompt you to supply a key pair name before downloading a private key to your client.

However, Access & Security under the heading Compute can not be found. I guess something might happen during the installation of packstack.

If you know how to fix the problem, please let me know.

We installed packstack to use openstack. The installation and access to the dashboard are successful but there is an error below.

Could you tell us how to solve the problem?
