If you want hosts on the network that the real servers are on
to be able to access the virtual servers, then you should use
LVS-DR. From there your minimal requirements are a machine
to acta s the linux-director, and a machine to act as the default
gw for the network, and of course some real servers. Note that
real servers can't access the cluster themselves (they always
just hit the local node), so you will probablyn need separate
machines for apache, xml-rpc and mysql.
