If sticking with PV then the vfb= option[1] would be needed to create a
suitable /dev/fb0 device to run X. PV guests have no graphics devices
by default and the posted guest config didn't include one.

If running HVM then it might be worth playing with the vga= option[0]
in the guest cfg to pick a graphics card better supported by the guest
distro. (stdvga might be a better choice than the default cirrus these
days).
