I think I have it figured out!

Edit your "/var/lib/xend/domains/<domain-uuid>/config.sxp" file.
Look for the lines containing

(on_xend_start ignore)
(on_xend_stp ignore)

and change them to be

(on_xend_start start)
(on_xend_stop shutdown)

This will restart the domain when the xend daemon starts.

Mine still fails for the case where I "reboot" the host instead of 
shutdown, powerup because it seems like it can not restart from the 
virtual machine image saved in "/var/lib/xen/save".  I tried to post a 
log file with that failure to this list but it looks like the e-mail was 
to large to post or something because it hasn't shown up in this list yet.

At least now I have a solution which will work when my UPS shuts down 
the server during a power outage.
