OVS 1.9.3 lacks full integration of interfaces file with open vswitch.

You will have to manually do a:

ifup --allow=ovs $list_of_bridges
ifdown --allow=ovs $list_of_bridges

Or add the above in a script.

1.10 and later has the following function that does the same in
/etc/init.d/openvswitch-switch
network_interfaces () {
    [ -z "${RUNLEVEL}" ] && return
    INTERFACES="/etc/network/interfaces"
    [ -e "${INTERFACES}" ] || return
    bridges=`awk '{ if ($1 == "allow-ovs") { print $2; } }' "${INTERFACES}"`
    [ -n "${bridges}" ] && $1 --allow=ovs ${bridges}
}
