Hello,

I am using devstack to deploy a 2 nodes setup (one controller/network/compute and one compute). The controller node starts correctly and I can launch instances without any problem:

All the services are started:

nova service-list
+----+------------------+---------------------------+----------+---------+-------+
| Id | Binary           | Host                      | Zone     | Status  | State | Updated_at
+----+------------------+---------------------------+----------+---------+-------+
| 1  | nova-conductor   | arbiter | internal | enabled | up    | 2015-03-27T18:31:36. | 
| 3  | nova-cert        | arbiter | internal | enabled | up    | 2015-03-27T18:31:29. | 
| 4  | nova-scheduler   | arbiter | internal | enabled | up    | 2015-03-27T18:31:32. | 
| 5  | nova-compute     | arbiter | nova     | enabled | up    | 2015-03-27T18:31:27. | 
| 6  | nova-consoleauth | arbiter | internal | enabled | up    | 2015-03-27T18:31:31. | 
+----+------------------+---------------------------+----------+---------+-------+

But when my compute node is deploying itself, after some time:

nova service-list
ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-83ea8582-fc02-48d9-a939-040b1eb9fcf4)

And when the compute node is completely deployed:

nova service-list
+----+--------------+--------------------------+------+---------+-------+
| Id | Binary       | Host                     | Zone | Status  | State | Updated_at    |  |
+----+--------------+--------------------------+------+---------+-------+
| 1  | nova-compute | zepler | nova | enabled | up    | 2015-03-27T18:31:56. | - |
+----+--------------+--------------------------+------+---------+-------+

It seems that the compute node stops all the nova services in the Controller node. How is that possible? I have MULTI_HOST=True for both my controller and compute node in the local.conf file.

Thank you for any suggestions :)
