Thanks Derek that seemed to work. However, aren't all AMQP derivatives going to 
have the same endpoint configuration? Why isn't amqp_host and amqp_port? 
Probably something for the openstack guys.

So now the compute node and the controller are communicating I'm getting a back 
trace when trying to launch an instance over there.

The last line is the important bit. Is there a way to run a glance client from 
the command line to the remote controller? Are there credentials for every node 
in the cluster and did they get corrupt somehow?

Thoughts?

Thanks,
