Title:
  Cannot launch instances from horizon

Status in OpenStack Dashboard (Horizon):
  Invalid

Bug description:
  Hi,

  I cannot launch an image from horizon:

  Error: The server has either erred or is incapable of performing the
  requested operation. (HTTP 500) (Request-ID: req-
  27902a03-9690-493b-8213-dae447df1b29)

  It says that it was unable to launch the instance.

  But it works well when I launch from the CLI, and then horizon can
  manage it.

  Logs are:

  It's like it cannot communicate with neutron. Or the nova-compute, I don't really know. 

  I have everything configured in controller node, but compute node has
  the neutron installation since it manages the network. I should surely
  install only the agents but didn't really know if it will work since
  the only hardware machine is on the cloud now is this compute node.

  
  This is the list of end point. As you can see fb019884661c417195ab753bf99fc854 is the neutron node and it's on the physical machine.

  I have to say that horizon can connecto to this because it's able to manage net. 

  So why it fails to create an instance?
