unfortunately, I have found that if it runs with an older version of 
xen, it will fool you by mostly running on 3.0.  I would seriously 
recommend building a new guest image.  It's not terribly difficult, only 
time tedious.  the steps below work for me on ubuntu but there's nothing 
keeping it from being distribution independent.
"install" onto a file disk image using qemu
create a new partition-less disk image
mount the root partition on a loopback device using losetup
mount your partition-less disk image also using a loopback device.
cp -a from the root partition to the partition-less disk image
cp -a domU modules onto the partition-less disk image
fixup fstab, host names, ethernet interface definition (there are 
probably more but I can't remember right now)
unmount everything (very important as my recent experiences shown ;-))

Create your .xm file

xm create ...

I believe this will give you better results.  Or if you prefer, I can 
also make available an ubuntu very raw disk image (i.e. fresh out of the 
qemu oven).
