Thanks to all for your answers.
So, it seems that I'll not be able to get the topology I describe in my
first post.. and I'm stucked with vnc.
Now I have two choices, either:
- run my gnome desktop from dom0 and use vnc to start a "remote"
gnome-session in domU, which I really don't want. I agree that dom0
should be as slim as possible and should only run the necessary modules
(and definitively not play the role of a gnome development
workstation!!)
- buy another PC, install FC5 and vncviewer then start a remote gnome
session to my xen/domU server. That sounds silly, if I buy another PC,
then I'll perform my development works on that PC, and not start a
remote gnome X desktopto the domU server...
Anyway, I hope that soon, we'll be able to run a gnome X desktop in
domU (At least be able to assign all the required resources -video card
etc..- to ONE of the domU in the xen domain space)
(I hope that i configured thunderbird correctly to send this message in
plain text...)

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...)
