First thanks to everybody for your answers.
In fact I forgot to tell some things about my configuration :
I use xen-2.0.7. If I am not using Xen-3 it is because I need support for 2.4
kernels, and because I want the direct PCI devices access.
Also I just try with a Debian domU (also 2.4.30), and I have the same error
about missing /dev/tty0, even if no error message are displayed at boot time
(so don't seem to be a Gentoo specific error).
I also try : # X vt1 , resulting in "missing virtual console 1" for the
debian domU and
Fatal server error:
xf86OpenConsole: VT_GETMODE failed
for the Gentoo domU.

Exactly ! ;) Like said in my first post I used Gentoo Linux for both dom0 and
domU. What I did is hidden the video card for dom0, with the option
physdev_dom0_hide and give access to the video card to my domU, with option
pci=[...] in its configuration file (remenber I use xen2). I also add support
for device driver domain in the Linux kernel, and as I obtained a compilation
error, I add the option for privileged domain (after searching in google, if
compiling the support for device driver domain, we MUST add the privileged
option support... so is my domU could also manage domains ?(I hope no....)).
In my domU:
domU ~ # ls -l /dev/tty*

I also add the support for virtual terminals in the Linux kernel (I try, don't
know if really needed), and now startx returns :
Fatal server error:
xf86OpenConsole: Cannot find a free VT
and X vt1 always :
Fatal server error:
xf86OpenConsole: VT_GETMODE failed
Sorry for the size of this post, but I think that I gave all needed information,
no ?
thanks guys.
