Ok, this is documented out there, I was just missing it. I've found my answer. In case anyone else runs into this issue, here is the procedure to fix:

* stop the running DomU's
* cp a backup of their config file somewhere, in case you hose the config accidentally: cp /var/lib/xend/domains/{hast}/config.sxp /root/domUname_backup_config.sxp (or something that works for you)
* using your favorite editor, modify /var/lib/xend/domains/{hash}/config.sxp
* search for the option on_xend_start and change it from (on_xend_start ignore) to (on_xend_start start) * search for the option on_xend_stop (next line, actually) and change it from (on_xend_stop ignore) to (on_xend_stop shutdown)
* save your changes
* restart xend

Issuing a shutdown -r now on the xen server, however, does not appear to
wait for the domains to shutdown and on top of that, once rebooted, does not
start the domains.

I'm not familiar with configuration files under the directory you
mention, I configure Xen DomU's on CentOS 5 under /etc/xen.
To make a DomU automatically start on Dom0 boot I just add a symbolic
link from /etc/xen/auto to the appropriate DomU's config in /etc/xen.

Hope this helps,
