The IPVS kernel sync daemon is the feature that keeps the sessions going in that failover scenario. It seems to work fine for simple TCP connections.
Especially for some internal load balancing I do in the app stack, the IPVS sync is handy for enabling routine load balancer maintenance without causing long-lived connections to get torn down. I will say there's one other odd thing about it: ipvsadm -L does not show connections picked up from a partner load balancer, but they work anyway. I can live with this stuff so long as it doesn't kill IPVS or otherwise destabilize the machine.
