Title:
  cloud-init does not bring up all bridge interfaces created with
  openvswitch

Status in openvswitch package in Ubuntu:
  Confirmed

Bug description:
  Hi,

  In my systems (all of them where I have openstack), I found that
  cloud-init does not perform well. Mainly because the bridges I have
  were created with ovs.

  Since they are not ready at boot time it seems that the system got
  stalled for a few mins. And after boot not all services recover.

  For example rbdmap is not called again after the net is up.

  It may be the order where the things are done. Or maybe something
  worse. The problem is that cloud-init stalls for 2 mins on boot. RBD
  doesn't run because cloud-init starts in nonet mode. And the whole
  system becomes broken.

  It's curious that ceph-osd are re-run after net is up. So some scripts
  are relaunched. In fact two times. So they start to work well. But
  some others no.

  
  root at red-compute:~# ovs-vsctl show
  8d08d8e4-49f2-4243-b1db-7641984a8530
      Bridge br-ex
          Port br-ex
              Interface br-ex
                  type: internal
      Bridge br-int
          Port "eth1"
              Interface "eth1"
          Port br-int
              Interface br-int
                  type: internal
      ovs_version: "2.0.1"

  root at red-compute:~# cat /etc/network/interfaces
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).

  # The loopback network interface
  auto lo
  iface lo inet loopback

  # The primary network interface
  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 eth1
  iface eth1 inet manual
   up ifconfig $IFACE 0.0.0.0 up
          down ifconfig $IFACE down

  auto br-int
  iface br-int inet dhcp

  And when I boot up, cloudinit does not find the interfaces so no
  network is up.

  I have to take an screenshot of the issue. The problem is that rbd
  storage is not boot up because cloudinit does not find the interfaces
  to connect to the intranet (because it's a bridge), and all the system
  becomes a nightmare.
