Thanks Kevin!
I'll dig into neutron.agent.linux.interface to see how it works. Before that,
would you give me any previews about what steps should be taken to add a veth
to a existed Neutron network?
Furthermore, is it Neutron who add a veth to ovs bridge or is it the Neutron
caller? (such as Nova)
Who's adding flows to ovs bridge? Neutron or caller?

Dastan

You want to look in neutron.agent.linux.interface to see how things are plugged
into OVS. That's the module used by the L3 agent to plug into OVS/linux
bridge/etc.
There is a well defined interface name format corresponding to the port ID and
the port ID, Mac address, and a couple of other things I can't recall are set
in ovsdb to help the agent identify the port as something it should care about.

I have to write a customized CNI plugin for our product, so it's better if I
know more operation details about how to interact with Neutron manually
(consider myself as Nova). Therefore Kuryr is not my best option right now, but
it's cool!

Hi,
Please take a look at Kuryr. Maybe this is what you are looking for.
Dan.

Hi everyone,
I'm new to OpenStack and currently interested in the Neutron part of it. What
I'm seeking is some advice about how to utilize Neutron independently, to build
a virtual network, for Docker containers maybe.
Suppose I've already got Neutron and Keystone installed on controller node and
compute nodes. I guess the following steps are required to test a virtual
network.
1) create a network
2) create a subnet
3) create two pairs of veths (each pair represents a vm)
for each pair of them:
4) create a port for one end of the veth pair (passing veth's mac address as a
parameter)
5) attach another end of the veth pair to ovs bridge
6) ping from one veth pair to another
The above is my general idea, don't know if it is correct and don't know the
operation details either.
Expecting your suggestions, any links are appreciated.
Regards,
Dastan
