I have followed following steps to configure lvs.

ipvsadm -A -t 192.168.1.2:80 -s rr

ifconfig tunl0 192.168.1.2 netmask 255.255.255.0

why do you have x.x.x.2 configured on both eth0:1 and tunl0?

Now I tried to open http://192.168.1.2 from the other
machine in 192.168.1.x network. Now I am able to get
only response from local machine that is
192.168.0.213,

Are the packets going through the director?

I am not getting the response from  my
other real server that is 192.168.0.234

do you have the default gw set correctly for the realservers?

When I execute ipvsadm -L -n I am getting below
result.
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
 -> RemoteAddress:Port           Forward Weight

Here it is showing that, It is sending request to both
real servers.

no. This shows that the ipvsadm table is set up to send to two realservers. The "0" entries show that no connections
are open.
