Dang, I'd love to see those numbers.  :-)

Understood.  Some questions ... is building an image that has libvirt
and qemu pre-installed from source good enough?  It avoids the
dependency on job runs, but moves it to image build time though, so it
still exists.

If the above still doesn't seem like a workable setup, then I think we
should just go straight to an image with fedora + virt-preview repo,
which kind of sounds easier, anyway.
