Public bug reported:
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

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."
