Let's just clarify a couple of things:

The filesystem where DomU's "content" is stored, and the filesystem
INSIDE DomU's content are different things. DomU doesn't need to know
ANYTHING about what the first is, but it does need drivers and tools to
use the content (of course). 

You can for example use ext3 to store a image-file that contains NTFS
for Windows. Dom0 doesn't need to have a NTFS driver, and DomU Windows
doesn't need a EXT3 driver. 

The only exception, as I know of, is that you can't have reiserfs inside
reiserfs (because it uses some sort of magic word to recognize what
lives where, and when it finds this "in the wrong place" it will get
itself into a weird place where none of the original content of the
filesystem is accessible at all).
