Interesting. That yields:

which if I read it correctly suggests that it's pygrub which is slightly
broken. I will start reading the pygrub source to see if I can see what
is going on. It doesn't seem to have a man page.
The menu.lst which it is trying to parse reads:
default 0

Run pygrub manually against the block device / image file to see if
it can successfully extract a kernel and initramfs. If it can't,
that's your problem.
$ sudo /usr/lib/xen-default/bin/pygrub -q /dev/vg00/domu_ns2lug_xvda
