Thanks!!!! The key, hinted at by various notes in this thread, was the
use of the "--location" to point to a network accessibleinstallation
repository. I'm afraid that the Xen wiki directions about "--location"
are a bit unclear about the need for this to be the base of a
deployment directory, one that *must* have a working subdirectory
called 'imagex/xen' with the relevant files in it. I admint, I have to
just love hardcoded, hidden requirements!!!

I'll point out for others who may need to image systems quickly that
it's often more effective, especially in terms of speed and external
bandwidth, to use an internal mirror as you did. I'll also point out
that it can be awfully handy to keep such a mirror up-to-date and use
it your local configurations. I publish such scripts at
https://github.com/nkadel/nkadel-rsync-scripts, in case anyone else
wants them.

I'll also mention my old habit in ks.cfg files of doing this, to hang
onto the actual ks.cfg instead of the confused and '%pre' and '%post'
stripped, anaconda reverse engineered oddness in

     cp -f /tmp/ks.cfg /mnt/sysimage/root/ks.cfg
