Bug Description

The cinder-scheduler service resolves the host to send messages to as:


This results in a tcp connection being opened to a non-existant host:

2014-10-16 09:51:07.086 12389 DEBUG oslo.messaging._drivers.impl_zmq [-] Connecting to tcp://juju-jpos-machine-5@cinder-ceph:9501 with PUSH __init__ /usr/lib/python2.7/dist-packages/oslo/messaging/_drivers/
2014-10-16 09:51:07.087 12389 DEBUG oslo.messaging._drivers.impl_zmq [-] -> Subscribed to None __init__ /usr/lib/python2.7/dist-packages/oslo/messaging/_drivers/
2014-10-16 09:51:07.088 12389 DEBUG oslo.messaging._drivers.impl_zmq [-] -> bind: False __init__ /usr/lib/python2.7/dist-packages/oslo/messaging/_drivers/

and no message ever being sent - the volume sticks in creating state.

OpenStack Ocata/Cinder 10.0.0: the bug is still exist.

Note: When I tries to create the volume cinder-wsgi starts load CPU to 100% and the volume creates with "Error" status.
