Hi Sameer
    I am using 32 bit Centos Release 5. For adding services to ipvsadm , 
i am using weighted round robin scheduler.
    Here is My configuration file format which'll be read by a daemon 
and then through that daemon it'll be added to ipvs table.
        <|groupinfo 1>
            <groupname  vods>
            <status           on>
            <group_ip     220.223.227.245>
            <group_port  5000>
        <groupinfo|>
 <|group 1>
            <|server 1>
                <hostname vods1>
                <status on>
                <server_ip 192.168.10.10>
                <weight            2>
            <server|>
 <group|>
The above configuration will be converted into the following format :
ipvsadm -A -t 220.223.227.245:5000 -s wrr
ipvsadm -a  -t 220.223.227.245:5000 -r 192.168.10.10 -w 2
Here i am getting the desired results but dmesg and ipvsadm commands 
gives the warnings that i have described earlier
