Hi Christophe,

I've been reading the thread but I think your configuration looks
correct. Can you give it a shot at using VNC to see if the VM is
booting up correctly? Maybe there's a problem with the VM...

Add the following to your ONE template:

GRAPHICS = [
  TYPE    = "vnc",
  LISTEN  = "0.0.0.0",
  PORT    = "5900"]

Start the VM and connect to it via a VNC client (for instance
vncviewer). Inspect the VM to see if there's a problem with it.

Regards,
Jaime
