That will not be good to me, as I try to isolate the Xorg world from the
host as much as possible (ie I don't want Xorg in my host).

That's the target solution.

That's what I tried, but I was not successful at it.

This is now "SYS_RAWIO", and should be set in "bcapabilities" file of the

I proceed with "mkdir -p /vservers/myguest/dev/input && cp -a
/dev/input/mice /vservers/myguest/dev/input/"

I did the same way : "cp -a /dev/tty7 /dev/tty8 /dev/tty9

Cped /dev/mem and /dev/kmem.

Then played with xorg.conf.

I'm successfully seeing my Xfce4 desktop with "startx" (.xinitrc contains
"exec start-xfce4" or something like that).
The problem is that I can't move the mouse or type to the keyboard : nothing

Thanks anyway.
