You'll want to look at the logs for the individual service.  Since you were 
trying to create a server instance, you probably want to start with the logs for 
the "nova-api" service to see if there are any failure messages.  You can then 
check the logs for "nova-scheduler", "nova-conductor", and "nova-compute". 
There should be something useful in one of those.
