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 ....
