Open Stack

I guess I've got something:

2013-09-23 16:52:17     INFO [cinder.openstack.common.rpc.common] Connected
to AMQP server on localhost:5672

I've found this page
https://ask.openstack.org/en/question/4581/cinder-unable-to-connect-to-rabbitmq/
and zipmaster07
answered "rabbit_virtual_host = /nova

I commented out the "rabbit_virtual_host", restarted all cinder services
and I can see a successful connection to AMQP now."
And I did that, now it's connected, but what is this rabbit_virtual_host?
What does it do?
I'll test my volumes now.

Regards.
