What does /etc/xen/test0.cfg contain? I suspect it is reusing the dom0
initramfs and hence has inherited some sort of hook script which insists
on the RAID stuff being present.

That would be a bug in either xen-create-image or something relating to
initramfs generation (initramfs-tools or some raid related hook file
provided by whatever package provides such things).

Note that xen-create-image is a separate project/package from xen
itself. (As are initramfs-tools etc obviously).
