Hi guys! After a fresh install of nova (Mitaka according to this documentation http://docs.openstack.org/mitaka/install-guide-ubuntu/nova.html (http://docs.openstack.org/mitaka/inst...)) on the controller node, I checked the status of services with the command:

 openstack compute service list

I got this output:

+----+------------------+--------------+----------+---------+-------+----------------------------+
| Id | Binary           | Host         | Zone     | Status  | State | Updated At                 |

|  4 | nova-scheduler   | oscontroll01 | internal | enabled | up    | 2016-05-26T14:52:53.000000 |
|  5 | nova-conductor   | oscontroll01 | internal | enabled | up    | 2016-05-26T14:52:48.000000 |
| 15 | nova-compute     | oscompute01  | nova     | enabled | up    | 2016-05-26T14:52:47.000000 |
+----+------------------+--------------+----------+---------+-------+----------------------------+

So, everything seems OK.

I also checked with the commande:

nova-manage service list

Adn then I got this output:

Option "verbose" from group "DEFAULT" is deprecated for removal.  Its value may be silently ignored in the future.
DEPRECATED: Use the nova service-* commands from python-novaclient instead or the os-services REST resource. The service subcommand will be removed in the 14.0 release.

After that, I checked if something is listening on port 8774 (osapi_compute) and 8775 (metadata) with this command:

netstat -tapun | grep 877

I got htis ouput:

tcp        0      0 0.0.0.0:8774            0.0.0.0:*               LISTEN      18082/python

I assumed that the services are running, I can also telnet on those services and they are responding.

I searched this symptom on the net, but found nothing.

Any help will be really appreciated
