on real servers use sysctl to set:
net.ipv4.conf.ethX.arp_ignore=1
net.ipv4.conf.ethX.arp_announce=2
ethX - shoud be the relevant network interface.
or add those lines to /etc/sysctl.conf on all nodes and reboot or do
"sysctl -p"
then configure the relevant interfaces on the nodes with the virtual IP.
