You haven't said how you are managing your domU's. If you are using the
bog-standard xm commands, you just need to rename the symlinks in
/etc/xen/auto to get the order you want, eg. 01-ldap.cfg 02-krb.cfg ...
I just wish the shutdown is similarly flexible, but it would just take a
bit of modification to the shutdown script to achieve it.

If you are using pacemaker to manage stuff, I think I saw some sort of
dependancy mechanism there. I have no idea what libvirt has available.
