Open Stack

Javier,

The stack trace you provided indicates that the allocate network call from
Compute (to nova-network) timed out. I would suggest checking the
nova-network logs, that might give some insight.
Also, IMO, the create instance request is being served by Compute means the
RabbitMQ is working. You might want to ensure that nova-network has also
connected to the same AMPQ server (as Compute is).

Regards,
Unmesh G.
