LVS can run on 2 server only?

["Eric Chan" <eric.chan@xxxxxxxxxxxxxxxxx>]

Hi, 

We have only 2 linux server, however we want to use the LVS load balance 
feature. Is it possible for one server to play both the role of director and 
real server?  (P.S. Each linux server has 2 ethernet ports). If it is possible, 
how should we configure the server? 

I have plugged  4 cables to a hubs, 2 from each server and setup the LVS. 
However, client request can only go to one server. ipvsadm -L -n show that 
there are inActConn for one server and ActConn for the other one.  Thanks a lot 
for your reply.
