if you use LVM, you can create an LV for each "disk" you want a domU to 
have, you can then expand the LV and then expand the filesystem iside it 
(or reduce the filesystem, then reduce the LV)
Unfortunately the last time I checked xen doesn't report the changed LV 
size "live" to the domU, so you'll need a reboot of the domU.
