I have managed to start the domain but changing to cfg file, but it
dies with a kernel panic

XENBUS: Device with no driver: device/vbd/51712
XENBUS: Device with no driver: device/vif/0
XENBUS: Device with no driver: device/console/0

Kernel panic - not syncing: Attempted to kill init!

cfg file:

name = 'test-rawimage'
kernel = '/boot/vmlinuz-' # Dom0 kernel
ramdisk = '/boot/initrd-' # Dom0 ramdisk
memory = '256'
disk = [ 'file:/mnt/disk-lappy.img,xvda,w' ]
vif = [ '' ]
#bootloader = '/usr/bin/pygrub' #Commented
on_reboot = 'restart'
on_crash = 'restart'

I have seen this problem in the list before and there is a solution
but i don't remember..
