[Fedora-xen] How to expand the file created by xenguest-install?

[Ben]

Sorry, I should have been more clear. When you create the domU, you need to give 
it an LVM logical volume. As far as the domU is concerned, it's just a disk. But 
from the dom0 side, it's an easily expandible partition. After you grow it, use 
tools on the domU side to expand the filesystem.

There's really no point in trying to expand a swap partition because you can 
just make another one.
