Open Stack

imagine a scenario in which rabbitmq were to fail to poll the nova-compute
service and put the system into an inactive state... yet, the instances
were still up and operating as expected.

i am not sure there is a way for openstack to ensure down or up in the
scenario in which message bus communications are severed.  so i don't see a
benefit either assuming down or coasting with previous values until
otherwise updated.
