That's not strictly speaking true. I have a Centos 5.2 host running
RedHat 5.3 & 4.6 guests. I also believe that it should be possible to
run a Redhat 3 guest as well, but I haven't tested it. You do have to
kludge around with the environment a little to run the older distros on
it, but it should be possible.
