Can we move the discussion of deprecating veth pairs to here?

https://review.openstack.org/323310
As you can see in the related bugs and linked patches there are some
complications. Some of the veth config options were already deprecated
and the

It relies on a side effect of their existence - iptables rules being
applied to the veth interface. It does nothing to the actual linux bridge
itself. If there was a way to plug a veth

I'm not a fan of this approach because it requires coordinated assumptions.
With the OVS hybrid plug strategy we have to make guesses on the agent side
about the presence of bridges with specific names that we never explicitly
requested and that we were never

Yep, and both strategies depend on that "create if not exists" logic so it
makes sense to at least get that implemented while we continue to argue
about which strategy to use.

Ok, so we're
In strategy 2 we just pass 1 bridge name to Nova. That's the one that is
ensures is created and plumbs the VM to. Since it's not responsible for
patch ports it doesn't need to know anything about the other bridge.

Strategy 1 is being pitched to make it easier to implement with the current
internals of the Neutron OVS agent (using integration bridge plugging
events). I'm not sure that's better architecturally long term because the
OVS agent has to have logic to wire up patch ports for the sub-interfaces

+1. Neutron should already be able to tell Nova which bridge to use for an OVS
port.[1] For the Linux bridge implementation it's a matter of creating vlan
interfaces

+1. Neutron should already be able to tell Nova which bridge to use for an
OVS port.[1] For the Linux bridge implementation it's a matter of creating
vlan interfaces and plugging them into bridges like regular VM ports, which
is all the responsibility of the L2 agent. We shouldn't need any changes

Here's a link directly to the current design proposal [1] that might
