That does seem odd.
For starters, ipvsadm -L indicates that there are 5 active connections,
they should show up in the output of ipvsadm -L -c.

Could you try
a) turning off persistence and;

and see what happens. I suspect that persistence is why your
requests always end up on the same real-server.
