Description Brent Eagles 2015-11-09 21:00:39 UTC
+++ This bug was initially created as a clone of Bug #1271335 +++

Support explicit configuration of L2 population in the overcloud:

The relevant configuration options are made to ml2_conf.ini on the controller.

# Insert l2population into the list of ML2 mechanism drivers
mechanism_drivers=...,l2population, ...

# enable l2 population in the agent configuration on all nodes running the agents
# (computes and network controllers)
# for openvswitch
l2_population = [True|False]

# for linuxbridge
l2_population = [True|False]

Patch u/s for review to enable the variable in heat. It can be enabled/disable through a parameter override in a heat environment file at deployment time. Support for mechanism driver configuration already exists so it should be configurable the same way.

Hi Brent,

It looks like your upstream patch is merged now. Can you confirm that this is going to be included with OSP-8 or do we need a backport for that?


Comment 5 Brent Eagles 2016-01-05 13:42:19 UTC
Hi Nir,

I checked with Mike Burns and it seems like a rebase is expected so this should get in. We'll need to keep an eye on it.
