I attached "grub.cfg". I use the menuentry 'Debian GNU/Linux, avec 
hyperviseur Xen'.
> Xen and dom0 kernel boot logs
"efi-grub-xen_dmesg_1-core.txt" contains kernel boot logs (`dmesg`), and 
"efi-grub-xen_xl-dmesg_1-core.txt" contains Xen boot logs (`xl dmesg`).
Let me know if you need more things.

Guillaume
