Well, according to the Xen list, it is really up to your requirements,
and they don't seem to have a lot of RAM for dom0 (and no swap
either, which is exactly what I am testing at the moment). But to be
on the safe side, 128MB sounds like a minimum requirement although I'd
sleep better knowing it has 256MB allocated.
