Linux – Keepalived loses VIP upon power cycle of master

I have two servers running Keepalived 1.2.7 with hostnames left and right. Here are the configs:

# keepalived.conf on left
vrrp_instance VI_1 {
    state MASTER
    interface eth1
    virtual_router_id 51
    priority 160
    advert_int 1
    virtual_ipaddress {
        10.10.10.200
    }
}

# keepalived.conf on right
vrrp_instance VI_1 {
    state MASTER
    interface eth1
    virtual_router_id 51
    priority 100
    advert_int 1
    virtual_ipaddress {
        10.10.10.200
    }
}

Now I power cycle left. Here are what the syslogs look like, interleaved and annotated:

>> neither has 10.10.10.200 <<

I was expecting left to take back 10.10.10.200 when it came back up. Why doesn't it? How can I modify my keepalived.confs so that it does?
