The URL for the volume service should point at the host(s) running the nova-api front end.  Nova-volume listens to the appropriate AMQP channel to perform the necessary LVM commands.

My nova-volume endpoint is specified in keystone as 'http://essex4:8776/v1/$(tenant_id)s'. With the above connection failure, nothing is written to the nova-volume.log (which makes sense if the server isn't listening to port 8776). Obviously, none of the other nova volume commands work.
