[ovs-discuss] openvswitch-2.0.1 in debian

[Tim Wolf]

Hi all,

I'm not sure, if I'm in the right forum, but I can't figure out, if my
problem on restarting the machine depends on Debian or Open vSwitch:

Following configuration:

Debian Wheezy
Open vSwitch 2.0.1 (selfbuilt packages, installation without errors)

This is my "/etc/network/interfaces" with blanked out IPs:

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto br0
allow-ovs br0
iface br0 inet static
        address 85.###.###.###
        netmask 255.255.255.255
        network 85.###.###.###
        broadcast 85.###.###.###
        gateway 85.###.###.###
        ovs_type OVSBridge
        ovs_ports eth0
        pre-up ifconfig $IFACE up
        post-down ifconfig $IFACE down

auto eth0
allow-br0 eth0
iface eth0 inet manual
	address 0.0.0.0
        ovs_bridge br0
        ovs_type OVSPort
        pre-up ifconfig $IFACE up
        post-down ifconfig $IFACE down


# The secondary network interface (over openvswitch)
auto br1
allow-ovs br1
iface br1 inet static
        address 10.###.###.###
        netmask 255.255.255.0
        network 10.###.###.0
        broadcast 10.###.###.255
        ovs_type OVSBridge
        ovs_ports eth1
        pre-up ifconfig $IFACE up
        post-down ifconfig $IFACE down

auto eth1
allow-br1 eth1
iface eth1 inet manual
	address 0.0.0.0
        ovs_bridge br1
        ovs_type OVSPort
        pre-up ifconfig $IFACE up
        post-down ifconfig $IFACE down

up route add -net 10.48.0.0/16 gw 10.###.###.1 dev br1

# end of /etc/network/interfaces #
##################################


Starting manually all works fine:

# ovs-vsctl add-br br0
# ovs-vsctl add-br br1
# ovs-vsctl add-port br0 eth0
# ovs-vsctl add-port br1 eth1
# /etc/init.d/networking stop
# /etc/init.d/networking start
# route add -net 10.48.0.0/16 gw 10.###.###.1 dev br1


But on booting the system, the ovs-database has "forgotten" its entries,
I think because of boot order, messages during boot are:

# ovsdb-server is already running.
# ovs-vswitchd is already running.
# Enabling remote OVSDB managers.
#
# br0: ERROR while getting interface flags: No such device
# Failed to bring up br0.
# br1: ERROR while getting interface flags: No such device
# Failed to bring up br1.


Again, starting all things manually works!


Is anyone there, who's got a similar setup working?


Thanks and greetings,
