[ovs-discuss] getting openvswitch config integrated debian interfaces network file

Hello everybody,

I am looking for the correct way to use /etc/network/interfaces to
create an openvswitch bridge/bond with a vlan.

Using /etc/network/interfaces is important, because the order of
start-up scripts is honoured and it is the Debian way to go. (the
iscsi and kvm systems need a reliable shutdown and boot order).

As work around I put everything in /etc/rc.local


root at kimberly:~# cat /etc/rc.local
#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

ovs-vsctl del-port bond0
ovs-vsctl del-br ovsbr1
ifconfig eth0 up
ifconfig eth1 up
ovs-vsctl add-br ovsbr1
ovs-vsctl add-bond ovsbr1 bond0 eth0 eth1 bond_fake_iface=false\
bond_mode=balance-slb lacp=active other_config:lacp-time=fast\
bond_updelay=400 bond_downdelay=400\
ovs-vsctl set port ovsbr1 tag=2
ifconfig ovsbr1 up
dhclient ovsbr1

/etc/init.d/open-iscsi start

###

This will boot up my system correctly note:
 /etc/init.d/open-iscsi start
Is something we do NOT want.

How can I implement the above rc.local in /etc/network/interfaces:


root at kimberly:~# cat /etc/network/interfaces
/etc/network/interfaces
auto lo
  iface lo inet loopback

auto eth0
iface eth0 inet manual

auto eth1
iface eth1 inet manual

allow-ovs ovsbr1
iface ovsbr1 inet dhcp
ovs_type OVSBridge
ovs_ports bond0

allow-ovsbr1 bond0
iface bond0 inet manual
ovs_bridge ovsbr1
ovs_type OVSBond
ovs_bonds eth0 eth1
ovs_options bond_mode=balance-slb lacp=active tag=2
