Did ubuntu install a Xen capable kernel and is grub within the guest
correctly pointing to it?

You can usually use kpartx to expose the partitions
of /dev/vgubuntu/ubuntu in dom0 and mount it to poke around.

I don't know which kernel flavour you need to have installed in Ubuntu
to get Xen support. Perhaps someone else chime in.

The other thing to consider is the use of LVM for the guest /boot. IIRC
this does not work with pygrub.
