As you can see in this line the sshd is blocking the port 22. So 
keepalived can not use this port.

Just move sshd out of the way.

Change in

/etc/ssh/sshd_config

the line

Port 22

to e.g.

Port 2222

and perform a

/etc/init.d/ssh restart
/etc/init.d/keepalived restart

To connect to this machine directly via ssh you will now have to use

ssh -p2222 gerry@<vip>

All others using

ssh gerry@<vip>

will land via the ipvs on your realservers.

Best Regards,

Volker
