No.
One way to get around this is to use a tool which changes
the LVS rules. So the Master would have the LVS rules
but the Standby would not. If the Master fails then
the Satndby has the rules instantiated.
This can be achieved using heartbeat + ldirectord.
I have some instructions on how to do this here:
http://www.ultramonkey.org/2.0.1/topologies/sl-ha-lb-overview.html
It is probably also possible to do this with keepalived.

There also many other ways to do this using different
software packages.
