[openstack-dev] [Fuel] ML2 support in Fuel deployment risks

Fuelers, Andrew,
I've talked to Sergey V. today about ML2 support in Fuel. Our current
approach [1] is to port upstream puppet module for Neutron which has
support of ML2, however our Neutron module is significantly diverged from
upstream one (at least for Neutron HA deployment capabilities), as far as I
understand. Basically, there is a risk that we will get unstable Neutron
deployment in 5.1. Also, unless we have ML2, we are blocking others who
rely on it, for example Mellanox.

To mitigate the risk, there is a suggestion to start the work in two
parallel tracks: one is to continue porting of upstream puppet module, and
another one - port the only ML2 part into Fuel Neutron puppet module. This
will not take much time, but will allow us to have 5.1 reliable and with
ML2 in case of instability after porting external module.

Your opinion on this?
