Title:
  Can only launch one instance with Grizzly

Status in OpenStack Compute (Nova):
  Invalid
Status in OpenStack Quantum (virtual network service):
  New

Bug description:
  I have grizzly setup in basic 3 system multi-node: controller,
  network, compute

  I can launch from horizon only ONE instance, attempting to launch
  another builds directly into no-state. I feel a problem with quantum.

  in /var/log/nova/nova-scheduler.log on the controller all is there is:
  "Setting instance to ERROR state"
