Как настроить keepalived - не способный установить VIP

Я пытаюсь установить скомпилированный keepalived 1.2.19 на человечности 14.04 с обработкой отказа. Так или иначе виртуальный IP никогда не обнаруживается:

ip addr show eth0 


2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
        link/ether 08:00:27:60:7f:89 brd ff:ff:ff:ff:ff:ff
        inet 192.168.56.120/24 brd 192.168.56.255 scope global eth0
           valid_lft forever preferred_lft forever
        inet 192.168.56.121/24 brd 192.168.56.255 scope global secondary eth0:0
           valid_lft forever preferred_lft forever
        inet6 fe80::a00:27ff:fe60:7f89/64 scope link 
           valid_lft forever preferred_lft forever

Конфигурационный файл похож на это:

! Configuration File for keepalived
vrrp_script chk_haproxy {               # Requires keepalived-1.1.13
        script "killall -0 haproxy"     # cheaper than pidof
        interval 2                      # check every 2 seconds
        weight 2                        # add 2 points of prio if OK
}
vrrp_instance VI_1 {
    state MASTER
    interface eth0
    virtual_router_id 101
    priority 101        # 101 on master; 100 on backup
    virtual_ipaddress {
        192.168.56.150
    }
    track_script {
        chk_haproxy
    }
}

Это выглядит довольно основным для установки. Что я делаю неправильно?
