Public bug reported:

As of precise/quantal, keepalived does not honor the use_vmac directive.
Expected behavior is for keepalived to synthesize a virtual mac address
to go along with the virtual IP address.  This is important in
situations where systems do not accept gratuitous ARP as a means to fail
over a virtual IP address.

I have built a version against the latest upstream (1.2.7), which does
honor the use_vmac directive as expected.  below follows an example of
how it should look (see 6:):

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 08:00:27:36:14:4f brd ff:ff:ff:ff:ff:ff
    inet 192.168.4.105/24 brd 192.168.4.255 scope global eth0
    inet6 fe80::a00:27ff:fe36:144f/64 scope link 
       valid_lft forever preferred_lft forever
3: virbr0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN 
    link/ether a2:20:3b:c0:e0:1a brd ff:ff:ff:ff:ff:ff
    inet 192.168.122.1/24 brd 192.168.122.255 scope global virbr0
6: vrrp.90 at eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN 
    link/ether 00:00:5e:00:01:5a brd ff:ff:ff:ff:ff:ff
    inet 192.168.4.200/32 scope global vrrp.90
    inet6 fe80::200:5eff:fe00:15a/64 scope link 
       valid_lft forever preferred_lft forever
