Configuration Problem

I am trying to setup load balancing for smtp servers.  Seemingly, the
configuration file is ok.

ipvsadm -l doesn't return anything

My keepalive.conf is

global_defs  {
lvs_id  LVS_1
}
vrrp_instance  VI_1  {
       interface  eth1
       state  MASTER
       virtual_router_id  51
       priority  101                     # 101 on master, 100 on backup
       advert_int  1
       smtp_alert
authentication  {
auth_type  PASS
auth_pass  pass

}

       virtual_ipaddress  {
           192.168.0.249/24  brd  192.168.0.255  dev  eth0
}

 VIRTUAL_SERVER  192.168.0.249  25  {
   delay_loop  60
   lb_algo  rr
   lb_kind  DR
   protocol  TCP
   persistence_timeout  360

   real_server 192.168.0.245 25 {
   weight 1
       TCP_CHECK {
               connect_timeout 3
       connect_port 25
       nb_get_retry 3
       delay_before_retry 3
       }
   }
   real_server 192.168.0.244 25 {
       weight 1
       TCP_CHECK {
               connect_timeout 3
       connect_port 25
       nb_get_retry 3
       delay_before_retry 3
       }
   }
}
