Michael, had the ARP disabled on the VIP

Most probably it's not your problem, but I thought
I'd mention it anyway. This is for LVS + direct routing:

1) ARP is enabled on the LVS machine, where your VIP is

2) on the backend servers, we apply the following
   sysctl mantra for direct routing to work properly:

  net.ipv4.conf.lo.arp_ignore = 1
  net.ipv4.conf.all.arp_ignore = 1
  net.ipv4.conf.lo.arp_announce = 2
  net.ipv4.conf.all.arp_announce = 2
