[Bug 1084028] Re: openvswitch based interfaces not started in time during boot

[Max Krasilnikov]

Mee too. Ubuntu 14.04 + Openstack Kilo. Br-eth1 is not starting on system boot but if I do `ifup br-eth1` all things are doing well.
# grep -vE "(^#|^$)" /etc/network/interfaces.d/ovs-bridge.cfg 
iface eth0 inet manual
iface eth1 inet manual
auto br-eth1
allow-ovs br-eth1
iface br-eth1 inet static
        address 10.0.64.67/24
        gateway 10.0.64.64
        ovs_type OVSBridge
        ovs_ports bond1
allow-br-eth1 bond1
iface bond1 inet manual
        ovs_bridge br-eth1
        ovs_type OVSBond
        ovs_bonds eth0 eth1
        ovs_options bond_mode=balance-slb lacp=active

Title:
  openvswitch based interfaces not started in time during boot

Status in openvswitch package in Ubuntu:
  Fix Released

Bug description:
  If you create network interfaces (access ports) in openvswitch, and
  configure them in /etc/network/interfaces, failsafe.conf will kick in
  and the interfaces get configured after failsafe.conf exits. This adds
  two minutes to boot time.

  openvswitch config:

  ovs-vsctl show
  93e6b401-214b-4089-ac51-27ca43009cce
      Bridge "br0"
          Port "br0"
              Interface "br0"
                  type: internal
          Port "vlan128"
              tag: 128
              Interface "vlan128"
                  type: internal
          Port "bond0"
              trunks: [128]
              Interface "eth0"
              Interface "eth5"
      Bridge "br1"
          Port "bond1"
              trunks: [143, 145]
              Interface "eth1"
              Interface "eth4"
          Port "phy-br1"
              Interface "phy-br1"
          Port "br1"
              Interface "br1"
                  type: internal
          Port "int-br1"
              Interface "int-br1"
      ovs_version: "1.4.3"

  cat /etc/network/interfaces:

  # interfaces(5) file used by ifup(8) and ifdown(8)
  auto lo
  iface lo inet loopback

  auto eth0
  iface eth0 inet manual
        pre-up ip link set $IFACE up
        post-down ip link set $IFACE down

  auto eth1
  iface eth1 inet manual
        pre-up ip link set $IFACE up
        post-down ip link set $IFACE down

  auto eth4
  iface eth4 inet manual
        pre-up ip link set $IFACE up
        post-down ip link set $IFACE down

  auto eth5
  iface eth5 inet manual
        pre-up ip link set $IFACE up
        post-down ip link set $IFACE down

  auto vlan128
  iface vlan128 inet static
      address 172.17.128.102
      netmask 255.255.255.0

  I expected openvswitch (interfaces/ports/bonds/trunks) to be up-and-
  running before /etc/network/interfaces gets evaluated.

  Clint Byrum (Ubuntu) reported me the following:

   "failsafe.conf will exit when all interfaces marked as 'auto' are "up". The
  only time you get a 2 minute delay is when it takes that long to bring those
  interfaces up. Since you have these vlanXXX interfaces listed, the system
  is waiting for them to come up.

  It seems to me that openvswitch needs to be brought up before runlevel 2, and
  so probably needs an upstart job. This sounds like a clear bug."
