No, it's not a stupid question.

However I didn't find a general answer to that question, so I asked
myself two different questions.

How do I install two or more linux distributions onto a disk
containing several root filesystems so that can I boot into any
the distributions?

Having solved that, I asked myself:

Which distribution/root filesystem will be the dom0 and how
how do I bring up the Xen and the dom0/domU's?

I made things more difficult for myself by wanting to just use the
one box, but there is no reason why you couldn't use two
physical machines. One box runs Xen and contains filesystems for
each domain. The second box is just a 'scratch' box. You install
a distribution on the second box, copy the filesystem image to the
first box (new domain), then wipe the disk on the second box ready
for a fresh install.

I have found that getting an arbitrary distribution to install
on a virutal machine of any type is sufficiently difficult that
it is often easier not to bother and to use a physical machine
instead.
