Your above recipe differ from mine just by using the host devices as is (i.e. not creating different devices on the non-running guest /dev). Did you try it ? I don't think this will work, because what I'm really doing is mapping the HOST /dev/loop7 into the GUEST /dev/hda, and (HOST) /dev/mapper/loop7p1 into (GUEST) /dev/hda1. I don't have /dev/hda in the host /dev but I need it the guest /dev. You can use mount -bind of /dev if you also create the right sym-links e.g. ln -s /dev/loop7 /dev/hda and ln -s /dev/mapper/loop7p1 /dev/hda1 but then you may have problems if the host have a real /dev/hda. You may skip the sym-linking and change the grub device map (/boot/grub/device.map) to have the line: (hd0) /dev/loop7 but then you may have other problems (grub-install want find /dev/loop71, you would not be able to run grub-install from within the guest itself without restoring the device.map .
