otoh, for those who aren't familiar, Zones are NOT virtual machines, 
they are simply virtual USER spaces.   all zones run directly under the 
'host' kernel.  the zones are more like a super-chroot, aka bsd 'jail', 
they have their own /etc/passwd and so forth, but they do NOT have the 
capability of running different OS's.
