In Xen, you can only prorate things, which are physically there. You can't
overcommit anything. If you want to do so, you've to use Virtuozo or its
free counterpart. In Xen, every DomU has to do its own swapping, so that
it could not thwart other DomUs.

The Xen answer: Hard drive space is cheap in these days.
