Its unfortunate that most other distros seem to have gone in the direction
of using some bootstrap / chroot method to installs guest FS images, because
its pretty much doomed to fail in a mixed host/guest environment such as
Ubuntu on Fedora. This is why the Fedora approach to creating guests has 
been to boot the regular installer (anaconda) using a xen guest kernel - it
lets people easily install Fedora guests on non-Fedora hosts.

There's a couple of options I can think of

  - Try and boot the Ubuntu installer using the Ubuntu  Xen guest kernel
    and hope it 'just works'.
  - Run the Ubuntu installer inside QEMU instance, and then install the
    kernel-xen inside QEMU. Finally shutdown QEMU & create  a Xen config
    file to boot the image created via QEMU
  - Use a bare-metal Ubuntu host to create the image & then copy it across
    to the Fedora host to run within Xen
  - Manually install debootstrap from sources on Fedora & see if you can
    get it working

If the first option doesn't work it'd be worth creating a bug report for
Debian recommending they try & get it working, because booting regular
installer with a xen guest kernel is by far the most portable way of 
creating guest images in mixed environments, since its totally isolated
from whatever the host happens to run.
