I assume hda5 is mounted RW in the dom0? Then xenUs should not write
to it too, so the tool obviously notices that and stops you from a
deseaster.

you could probably make it RO in xen0, or not mount it at all. If you
want to write something from dom0 to a domU, you can either use
another partition (note that this may be a file in reality, but the
xenUs can only see it as a block device (if you config it all that
way)) or you can wait for XenFS. Mark will probably announce when
xenfs is ready.
