OK, I'm an idiot.
If I understand correctly, nova-volume provides the 'backend' service. So to
run nova-volume on a separate node, I apparently have to also install the
nova-api (and associated python-keystone modules)? Is this correct? Or will
the backend messaging (rabbitmq) allow the nova-api service running on one node
to correctly control the nova-volume backend on another node?
Thanks in advance!
