[Rdo-list] F20 networking refuses to start on boot

Actually, it looks like I'm experiencing the same issue with br-ex on
my F20 openstack install.  Given an interface configuration file
/etc/sysconfig/network-scripts/ifcfg-br-ex that looks like this:

  DEVICE=br-ex
  DEVICETYPE=ovs
  TYPE=OVSBridge
  BOOTPROTO=static
  IPADDR=172.24.4.225
  NETMASK=255.255.255.240
  ONBOOT=yes

After I boot the interface looks like this:

  br-ex: flags=67<UP,BROADCAST,RUNNING>  mtu 1500
          inet6 fe80::888c:81ff:febd:d8b8  prefixlen 64  scopeid 0x20<link>
          ether 3a:69:08:00:0f:40  txqueuelen 0  (Ethernet)
          RX packets 0  bytes 0 (0.0 B)
          RX errors 0  dropped 0  overruns 0  frame 0
          TX packets 8  bytes 648 (648.0 B)
          TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

Running ifdown/ifup as Pete describes correctly configures the
interface.

I'm starting up another F20 system right now to see if this is a
general problem with OVS bridges or if there's something peculiar on
my install.
