OK. There is just no reason to do RAID in a Xen virtualized environment
 unless you're testing out a driver. Let the Dom0 do all that work,
 because it's already managing the disk IO anyway. LVM to merge together
 different partitions or disks, and exporting an LVM partition for the
 DomU should and does work just fine.

If you don't use RAID 1 on your disk how will you protect  your data
against disk failure?

The somewhat obscured point of the message was: Don't do RAID in domU. Do it in dom0 instead.
