Generally, I've been slowly coming to the same conclusion.
Am I correct in my understanding that each DomU contains an instance of OS/kernel + app binaries in it's own virtual volume/file space, but that *data* (effectively, *any* dynamic content) is written by the DomU processes to/from the Dom0 hypervisor's volume/file space?
How about swap? Dom0 of course has its swap -- and could/should be RAIDed, but what about GuestOS' swap? I honestly haven't gotten that far yet ....

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!
