Since your actually forming the raid on dom-0 and not inside of the
guest, there is absolutely no need to load md and associated modules in
the guest at all. The guest will just see the volume group you are
exporting as a regular sata drive the same size as the vg being
exported.
I'm guessing the second drive is for swap?
Hope this helps
Best,
