It's worth remembering that LVS is application-unaware. If you want
something to do session persistence without IP persistence, you need
some way of making all of your realservers aware of all the clients
connecting to them - like memcached, for example.

Saying that this is a negative point of LVS is like saying it's a
negative point of TCP :)
