So, I've got a PV guest that works.

Now I shut it down, run this script, and do `xl create -c' on the
resulting config file, but it dies. :-(

I'm using what's in this branch https://github.com/aliguori/xen/tree/vi
xen-upstream-v2 both as the host hypervisor and as the shim.

So, here's what I see on what I think is vixen's console:
