Hey Guru,
I am trying to get the NetworkManager to bring up my gtp-vport using
/etc/network/interfaces.d/br0 but it isn't getting added. This is my config:
allow-ovs br0
iface br0 inet dhcp
ovs_type OVSBridge
ovs_ports eth0 gre0 gtp0
allow-br0 eth0
iface eth0 inet manual
ovs_bridge br0
ovs_type OVSPort
allow-br0 gre0
iface gre0 inet manual
ovs_bridge br0
ovs_type OVSTunnel
ovs_tunnel_type gre
ovs_tunnel_options options:remote_ip=182.168.60.141 options:key=1
allow-br0 gtp0
iface gtp inet manual
ovs_bridge br0
ovs_type OVSTunnel
ovs_tunnel_type gtp
ovs_tunnel_options options:remote_ip=flow options:key=flow
So the bridge is set up, and eth0 and gre0 are added. The gtp0 device is not
and there don't seem to be any errors mentioning gtp-vport that I can find. I
can also add the gtp-vport manually without issues:
ovs-vsctl add-port br0 gtp-vport -- set interface gtp-vport ofport_request=4
type=gtp option:remote_ip=flow options:key=flow
Do I need to register new a ovs_tunnel_type somewhere for it to work? Any way
to increase logging here?
Best,
Omar

The detailed documentation is here:

You can in effect do anything you want via the "ovs_extra" option. It takes
ovs-vsctl's datatabase manupulation commands.
e.g:
ovs_extra add-port br0 p1 -- set-manager ptcp:3332:192.168.1.2 -- blah

Looks like I was missing the kernel module. Added "openvswitch-datapath-dkms"
and it works now.
Thanks!

Hi Guru, Ben,
Thanks for the responses. I originally did a "make install" though I realized
there may be some packaging postinst scripts that may need to be run for it to
work. I built and installed openvswitch-common and openvswitch-switch.
"ifup --allow=ovs br0" still fails to find br0 but I've made progress
nonetheless in the networking journal
vagrant@magma-dev:/etc/network$ sudo journalctl -u networking
Oct 12 23:27:29 magma-dev ovs-vsctl[2127]: ovs|00001|vsctl|INFO|Called as

Oct 12 23:27:29 magma-dev networking[1875]: ovs-vsctl: Error detected while
setting up 'eth0'. See ovs-vswitchd log for details.

2017-10-12T23:27:31.123Z|00113|bridge|ERR|failed to create bridge br0: No such

What could be missing?
Best,
Omar

Hi list,
I am using OVS 2.7.90 with Debian 8.7 and want to configure the switch to be
loaded on system initialization. I have installed the service
"openvswitch-switch" and added the following in /etc/network/interfaces
How did you install OVS 2.7.90? By 'make install' or via debian packages?
allow-ovs br0
iface br0 inet dhcp
ovs_type OVSBridge
ovs_ports eth0
allow-br0 eth0
iface eth0 inet manual
ovs_bridge br0
ovs_type OVSPort
I am still unable to load br0 with ifup.
vagrant@magma-dev:/etc/network/interfaces.d$ sudo ifup br0
Lets try with:
ifup --allow=ovs br0
Cannot find device "br0"
Bind socket to interface: No such device
exiting.
Failed to bring up br0.
How do these interfaces get set up? Is there anyway to debug this? I've built
this package from source, so I want to make sure I am not missing dependencies.
Also should I be adding any additional systemctl units or should adding
"openvswitch-switch" be enough?
Best,
Omar
