I am trying to deploy openstack grizzly on a 12 node cluster. I want to use the xen hypervisor. I currently have xenserver installed, and I have 3 virtual machines running Ubuntu 12.04 to use for the control, compute, and network nodes.

Is it at all possible to combine the VM and Management Network into one physical network? I only have one router, so I need to use only one network. I got my setup pretty much working using this guide. But now, I only have access to a single physical network.

Is there a way to have VM and Management traffic on the same network? Security is not a concern at the moment.

You only have one router? Your router doesn't support vlans? Running a compute node inside a virtual machine is probably not a good idea. –  devicenull Aug 30 '13 at 0:04
Yes. I should have been more clear. All physical machines are plugged into an unmanaged switch, which is plugged into a router. The switch does not support vlans. As far as I can tell, running every node in a xen vm is the only way to use xen as the hypervisor. –  user2730940 Aug 30 '13 at 22:27
