Indeed.  I guess I need to think about restricting connections
to xend to localhost only - and maybe even through a unix
domain socket instead of a tcp socket ...

Note that I do not believe that xend access should be root
only, people may want to run management software under another
UID.  As long as domain 0 doesn't get any untrusted users,
things should be fine.
