Hello. I'm trying to install Juno release with Ubuntu 14.10 on 1 x86 machine using virtualbox.

As you see below, There are only 4 services are shown. nova-compute is NOT showed up. moreover, 4 services' state is "down".

root@controller:~# nova service-list

+----+------------------+------------+----------+---------+-------+------------+-----------------+
| Id | Binary           | Host       | Zone     | Status  | State | Updated_at | Disabled Reason |
+----+------------------+------------+----------+---------+-------+------------+-----------------+
| 1  | nova-cert        | controller | internal | enabled | down  | -          | -               |
| 2  | nova-consoleauth | controller | internal | enabled | down  | -          | -               |
| 3  | nova-scheduler   | controller | internal | enabled | down  | -          | -               |
| 4  | nova-conductor   | controller | internal | enabled | down  | -          | -               |
+----+------------------+------------+----------+---------+-------+------------+-----------------+

And, I couldn't find socket connection between controller and compute node. I found the connection right after the nova-compute restart at compute node. Socket connection must be down. There's no problem with ping between them.

Do you have any ideas about this problem?
