I believe it is because you edited "lo", you do that on the real servers not 
the LVS/ipvs directors even with HA, AFAIK. If you are using HA, I believe you 
want that 192.168.168.199 address to be an IPAddr or IPAddr2 HA Resource that 
gets moved to the other machine on failover. ldirectord does the rest I think.

And if you are running a recent kernel, you don't need/want to use 
LVSSyncDaemonSwap anyway the master/backup daemons can run on both 
simultaneously, I believe. See this comment by HAorms:
