LVS doesn't do IP fail over automatically, you need an external program. 
Are you using keepalived or heartbeat to fail over the IP? I use 
heartbeat running in symmetric cluster mode so both load balancers have 
equal number of VIPs, once one of them goes down the other takes over 
the VIPs. I would recommend heartbeat 2.x.
