Title:
  instance in openstack does not support bridge

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  hi

  i install openstack Grizzly which use quantum as network service ,and
  boot one instance ,now the instance can access external network,then i
  installed openvswitch-switch in that instance, create brideg, add
  port(eth0) to the brideg, restart network, At this time, we can not
  access gateway and external network,  below are my steps.

  ######################################

  #Intsall openvswitch
  apt-get install -y openvswitch-switch

  #Network Configuration
  vi /etc/network/interfaces
  auto eth0
  iface eth0 inet manual
  up ifconfig $IFACE 0.0.0.0 up
  up ip link set $IFACE promisc on
  down ip link set $IFACE promisc off
  down ifconfig $IFACE down

  
  auto br-ex
  iface br-ex inet static
  address 172.20.10.2
  netmask 255.255.255.0
  gateway 172.20.10.1
  dns-nameservers 192.168.1.3

  #Add bridge br-text
  ovs-vsctl add-br br-test

  #Add port(eth0) to br-text
  ovs-vsctl add-port br-ex eth0

  #Restart network
  /etc/init.d/networking retsrat

  ####################################

  ok,when i repeat above steps in physical server or vmware workstation
  or citrix xenserver ,any way,we can access external network.

  Thanks in advance !
