Hi!

If you think about the reasons of having a RAID1, which domains would be 
affected 
by a hardware failure, and what would you have to do then? If you think about 
it, 
everything seems logical. To avoid needless work and overly complex 
configurations, I'd mirror in Dom0 and export mirrored devices to DomU.
