Other thing :

There is a problem in a config default on file "lvs.cfg" the parameter
default in "keepalive" is *MINOR* than "deadline" , but this should be
change for something like this, example (keepalive  = 12 /  deadline = 4 )
if you don't change this option all the time if you check on both server
"watch -n.1 "ifconfig" " you will see the virtual interface
appearing/disapering in the backup server.
