Yes a default make world build of Xen 3.3, config attached.

I just read the <xen source tree>/stubdom/README file, particularly focusing
on the PV-GRUB section. The description matches my understanding, but
the results of using it do not...

This README does not appear to be installed to
the system in /usr/share/doc/xen, is it expected to be?

I based my configuration directly from the  /etc/xen/xmexample.pv-grub that
you suggest. I think I mis-worded my request for an example. I suspect that
my problem is either the disk image or some of configuration issue, is there
a smallish disk image that you could make available for me to use with its
corresponding config file so that I could get a known working disk image
to narrow down the isssue?
