Thomas,
I don't know if this has changed recently, but I've never been able to
reboot from inside a guest os. My reboot and shutdown scripts
actually simply have an 'exit' statement in the them. If I need to
reboot a guest os, I do it from the host with "vserver <guestname>
restart".

If you would like to allow your guest os administrators to reboot a
guest os without having access to the host system, you could try using
one of the web interfaces for vserver such as OpenVCP. You could also
just create a simple web page with links for each guest os that calls
the appropriate command on the host.
