Are you saying that there will only ever be 3 distinct clients
connected, and you want each of them to be balanced to a separate real
server?
If so, you must be pointing each client at their own virtual service
address, so you may as well do away with LVS altogether and just point
them at their own real server directly.
If not, just use one virtual service, load-balanced between your three
real servers equally (i.e. each real server has equal weight), but
consider using a persistence value, so that each client will 'stay' with
a real server for a certain amount of time... like this:
virtual=10.32.30.125:18007
real=192.168.0.10:18007 masq 1
real=192.168.0.20:18007 masq 1
real=192.168.0.30:18007 masq 1
checktype=on
virtualhost=eaivcon3.kdc.ird.govt.nz
scheduler=wlc
persistent=600
protocol=tcp
checkport=18001
service=http
request="/PingWebClient/pingApp.jsp"
receive="REPOUT"
... or then again, perhaps I am missing what you are getting at entirely 8-)

Yes - presumably the LVS director is load-balancing requests between the
three real servers. The weights probably only come into it once there
are a few connections happening.
