You will probably want to set the following (otherwise you have to
wait for the persistence to run down before current connections move
to another server)
echo 1 > /proc/sys/net/ipv4/vs/expire_quiescent_template
echo 1 > /proc/sys/net/ipv4/vs/expire_nodest_conn
Also If you are using ldirectord you will probably want quiscent=no set.
