With regard to the Dom0.  Im already using Jermeys kernel from his git
tree running pv_ops.  The config is one of the example configs with just
the changes made to match the domU name etc.

What does "xm list" show? is the domU created? If not, there should be
something in /var/log/xen/xend.log, recording when the domU failed to
startup, or shutdown, or crashed.

Also, since you say that some files failed to be copied earlier, the
easiet way that can I suggest is to try known-good config first. For
example, I'm using RHEL5.4 with Xen rpm from gitco. Once that works,
you can start changing some elements (like replacing dom0 kernel with
pv_ops).
