Hi Javi,

I'd like to run an X server in the container. My GPU card has two GPUs 
so I'd like run run one container with access to /dev/nvidia0 and the 
other one with access to /dev/nvidia1. As I want to use X rendering I 
need to start an X server in the container and I will access to this 
server through TurboVNC/VirtualGL.

The problem is that if I start an X server within the container by 
using xinit command I get the error:

Fatal server error:
xf86OpenConsole: VT_ACTIVATE failed: Invalid argument


I think that I have this error because with libvirt, /dev/ttyX is a 
link to /dev/pts/X. Currently I only try to start X server on /dev/tty1 
on my laptop without GPU but my final goal is to do it on a machine 
that has GPU.

I hope that I give a more clear picture of my goal :) Regards,
Guillaume
