There is an alternative to it actually.

What you're doing right now provides simplicity, at the cost of having
to restart domU after disk resize.

If you want the ability to add disks to domU online (without reboot),
you need to use LVM on domU as well. In that setup new disks can be
added to domU online using xm block-attach (and editing domU config
file, if you still use that). domU then uses that disk as a new PV to
extend its VG.
