Hello,

I'm using Kilo on three nodes (controller, compute, network) deployed by RDO.

When I create a instance, this error is output in nova-conductor.log.

2015-05-28 10:11:49.463 4197 WARNING nova.scheduler.utils [req-1acb7800-df4b-44dc-870f-3c02d9389000 70c277bb4adf462c9d0e7a6c4e9081be 5a7edd398ad74e07b9ee3d69b7b7ae0e - - -] Failed to compute_task_build_instances: No valid host was found. There are not enough hosts available.

And this error message is output in nova-compute.log

2015-05-28 09:59:17.129 2361 ERROR nova.compute.manager [req-3e97e0b2-819e-4996-aee1-68fc608bd275 - - - - -] No compute node record for host mido54

Here are some outputs. There is no hypervisor, Is this wrong?
