I'm going to be setting up a new server to run several Xen machines.  I
plan to have two drives and use (software) RAID for reliability.  I'm
curious how other people are doing this.

One apparent option, for the production DOMUs, is to have matching
partitions on each hard drive, and have the DOMUs do RAID themselves.  A
second is to use a large DOM0 partition, with RAID, and assign a DOMu a
file in that partition.  This strikes me as slower, but adequate for
light-load and experimental servers.

Of course, the real question is whether either or both options actually
work.
