Hi,
I'm currently testing OVS to replace default Debian bridge approach, when
using Xen. Because of many physical machines, we use puppet to configure
them, with which OVS works well (only had to build own package basing on
1.9.3, as official backports are using really old version).
Is there any way to enable LACP on server via config file, which will be
parsed on startup of OVS (what for us mean on boot of machine)?
There is integration with 'interfaces' file. Have a look at
debian/openvswitch-switch.README.Debian in the repo and test to see
whether it fits into your requirements.
I think 1.9.3 had support, but Open vSwitch startup script would not
call the following command (I think that happened in 1.10)
ifup --allow=ovs $list_of_bridges
(So, you may want to add a patch to the OVS startup script to do that.
Look at commit 1d63efc45b9ae5b723f9a8f0d81c7f002b48c39d for hints).
I updated OvS to 2.0.1 (self compiled on Debian Wheezy 7.4), as it's
also LTS and there startup fix calls ifup also. With documentation I
tried to configure ovs, to get same as I have now, only using interfaces
file. My current ovs-vsctl show output is:
ovs-machine:~# ovs-vsctl show
0a427b10-9530-4649-91fc-59b55226ac7a
Bridge "br0"
Port "bond0"
Interface "eth0"
Interface "eth1"
Port "br0"
Interface "br0"
type: internal
ovs_version: "2.0.1"
And /etc/network/interfaces file, which unfortuneatly doesn't work is:
#
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-ovs br0
iface br0 inet static
address 10.16.0.93
netmask 255.255.0.0
gateway 10.16.0.240
dns-nameservers 10.0.0.100
dns-search ig.local
ovs_type OVSBridge
ovs_ports bond0
allow-br0 bond0
iface bond0 inet manual
ovs_bridge br0
ovs_type OVSBond
ovs_bonds eth0 eth1
ovs_options lacp=active
allow-bond0 eth0
iface eth0 inet manual
ovs_bridge bond0
ovs_type OVSPort
allow-bond0 eth1
iface eth1 inet manual
ovs_bridge bond0
ovs_type OVSPort
After reboot with such config I get only lo0 up, eth0 and eth1 down. br0
is even not configured. OvS returns empty config for ovs-vsctl show.
Do you have any idea, where and what is wrong in this configuration?
found only way to do it via ovs-vsctl, but putting this rule to puppet is
not acceptable, as it would change network config immediately and brake up
rest of puppet run, before we change config on switch.
Currently I'm configuring bond over eth0 and eth1 by putting same db file on
all servers, when installing ovs there.
