Hello,
I've installed openstack liberty with TripleO. Overcloud is successfully deployed with 1 controller and 2 compute nodes.
When I try to create an instance it fails and the errors are:
From nova show: No valid host was found. There are not enough hosts available.
From the compute node: HTTPInternalServerError: 500 Internal Server Error: The server has either erred or is incapable of performing the requested operation. (HTTP 500)
And the full trace is :

Any hint in troubleshooting is highly appreciated. Thanks.
