The entire system I would install on HW RAID, and use LVM for
flexibility in domU configurations.  You can do things like take LVM
snapshots and have a clone of your system available for testing, for
instance.

In a recent Red Hat class that I took (RH436 - clustering and storage)
we had a dom0 and several domU's - all of the domU's were actually
snapshots of one "gold master" if you will, so that:

1) The amount of storage required is reduced
2)  The ability to quickly rebuild one of the domU's to a "known-good"
configuration.

Let me know if you have any further question!
