I would be very surprised if 10.3 didn't support Intel VT, altho' I've only
done SuSE PV installs. Where does it hang, during boot of the cd/iso?

Presumably you have done the Gnome System -> Preferences -> Look and Feel ->
Screensaver (gnome-screensaver-preferences), and -> System -> Power
Management (gnome-power-preferences) things, and make sure your timeouts are
suitably large, or disabled. Run the program in parenthesis in a 'ssh -X'
session from a remote client if your desktop is totally unresponsive. If you
move your mouse after the screensaver comes on, does your desktop come back
to life? If SDL, vnc, and xdmcp all bring up a screensaver, something must be
wrong with your timeouts.

Xinetd implies your vnc server is on the domu, instead of the dom0. Have you
tried the vnc server built into qemu-dm? (vncviewer localhost:port#)

You realize this refers to xdmcp, not vnc, right?

My experience with chooser boxes is that they may not see all available hosts
on a scan, but if you type in the hostname, you can connect. Make sure your
firewalls on domu and remote client are open, or off. I use 'sudo iptraf' to
see who is not responding during attempted communications.
Sorry I couldn't provide a definitive answer - just go over the basics again.
Good luck.
