It looks like my cute and paste did not work right. My br-ex device looks
like this:

DEVICE=br-ex
OVSBOOTPROTO="dhcp"
OVSDHCPINTERFACES="eth0"
ONBOOT=yes
NM_CONTROLLED=no
TYPE=OVSBridge
DEVICETYPE=ovs
DEVICE=br-ex
OVSBOOTPROTO="dhcp"
OVSDHCPINTERFACES="eth0"
ONBOOT=yes
NM_CONTROLLED=no
TYPE=OVSBridge
DEVICETYPE=ovs

Sorry about the confusion.
