#mknod /dev/xvda b 202 0

Edit /boot/grub/device.map:

Replace '(hd0) /dev/sda' with '(hd0) /dev/xvda'

Edit /usr/sbin/update-grub

Replace:

find_device ()
{
if ! test -e ${device_map} ; then
echo quit | grub --batch --no-floppy --device-map=${device_map} > /dev/null
fi
grub-probe --device-map=${device_map} -t device $1 2> /dev/null
}

With:

find_device ()
{
if ! test -e ${device_map} ; then
echo quit | grub --batch --no-floppy --device-map=${device_map} > /dev/null
fi
#grub-probe --device-map=${device_map} -t device $1 2> /dev/null

echo /dev/xvda
}

#update-grub 0
