Denis,
You can not run X on a DomU as the guest has no video hardware available, but you can do the following:
run "Xvnc :0" on DomU, this will start an X server that uses a pseudo-frame buffer as video-hardware and serves that framebuffer via vnc protocol.
now run "gnome-session" on DomU to start the whole gnome desktop infraestructure on the guest OS (as gdm will do)
Now, from dom0 that is the only one with a physical screen attached at, launch vncviewer and connect to domU-ip-address:0, this will show the remote virtual desktop.
hope this helps.
Raul.

Subject: [Fedora-xen] Gnome desktop in domU? (aka xorg and startx problems in domU)
I'm experimenting with xen on FC5 (as domU and dom0).
The idea is to have a machine running dom0 with 4 guests, one of the guest would be my workstation/desktop (with gnome running), the others guests would be application/file/utilities servers.
I would like to perform something like:
- logon to the domU via ssh, from dom0 for example (I also have tried it with "xm console domU" from dom0, the result is the same)
- run "startx" : that should bring the standard logon screen
- after login, use the gnome desktop as from a standard standalone workstation
But this does not work: startx does not start (first because the xorg.conf is not created. I've tried to run "X -configuration" to create xorg.conf, but the command fails also to create the xorg.conf file)
BTW, on dom0 "startx" and the gnome desktop run perfectly
Q:
- Is it possible to configure X and run "startx" in a domU (I've read somewhere on the net that this is not possible...). If so how to do it?
- What is the best way to get a full gnome desktop workstation that would run in domU like a standalone workstation?
I've tried the "vnc" solution, it works great but have limitations (at least for me). and would greatly prefer what I described previsoulsy:
(I don't know how to get the logon screen with vnc, the screen resolution can not be easily choosen/changed, the desktop to be somewhat "slower" than the "local" desktop)
Thanks in advance for any advice or pointer.
(I'm not really a newbee with linux, but I'm far from an expert...)
