It works over the network. I have all my vms on a server and i only access those vm's over network.

Below are both configs (kernel 3.7.10)(hope bpaste is ok). If you going to use them and don't use virtio-net make sure you enable appropriate net drivers (e1000,rtl8129,..), because i've disabled all of them. http://bpaste.net/show/93300/ http://bpaste.net/show/93301/
