Ugh this was a few months ago and I haven't done much with nova recently.
 IIRC, all you have to do is connect to the :1 vnc on the nova host.  So if
you have VNC and a GUI on your nova host, you can do that from the host with
your favorite vncviewer (ubuntu comes with remote desktop viewer) and
connect to :1.   So the string you would type into the remote desktop viewer
program would be

localhost:1

You can do this through ssh port forwarding as well.

Hopefully the above is sensical.
