What are you trying to do?
If just want to do some testing without having to download several GB,
you can try floppyfw (http://www.zelow.no/floppyfw/) and run it as HVM
domU. Only 1.4MB (the floppy version).

Another method is to build a custom initrd, with busybox installed as
/sbin/init and /bin/sh. That way you only need kernel and initrd for
PV domU, without the need of a dedicated root filesystem. You might
have to create the initrd yourself though.
