2014-01-03 15:50:37 -0500 asked a question Confused about controller and compute nodes

Hi I'm a little confused. I have two servers running xenserver with both having ubuntu 12.04 with openstack installed as the first DomU for each server. I'm wanting to know can I have the controller node and computer node on one server or do I need to have them on different servers. Or would xenserver be considered the controller. I'm lost at the moment.
