<br>
thanks for the information. I would love to see your patch getting<br>
merged to have l2-population MD fully functional with an OVS based<br>
deployment. Moreover, this patch has a minimal impact on neutron,<br>
since the code is used only if l2-population MD is used in the ML2<br>
plugin.<br>
<br>
markmcclain was concerned that no functional testing is done, but<br>
L2-population MD needs mutlinode deployment to be tested. A deployment<br>
based on a single VM won't create overlay tunnels, which is a<br>
mandatory technology to have l2-population activated.<br>
The Opensatck-CI is not able, for the moment, to run job based on<br>
multi-node deployment. We proposed an evolution of devstack to have a<br>
multinode deployment based on a single VM which launch compute nodes<br>
in LXC containers [1], but this evolution has been refused by<br>
Opensatck-CI since there is other ways to run multinode setup with<br>
devstack, and LXC container is not compatible with iscsi and probably<br>
ovs [2][3].<br>
<br>
One way to have functional test for this feature would be to deploy<br>
3rd party testing environment, but it would be a pity to have to<br>
maintain a 3rd party to test some functionalities which are not based<br>
on 3rd party equipments. So we are currently learning about the<br>
Openstack-CI tools to propose some evolutions to have mutinode setup<br>
inside the gate [4]. There are a lot of way to implement it<br>
(node-pools evolution, usage of tripleO, of Heat [5]), and we don't<br>
know which one would be the easiest, and so the one we have to work on<br>
to have the multinode feature available ASAP.<br>
<br>
This feature looks very important for Neutron, at least to test<br>
overlay tunneling. I thinks it's very important for nova too, to test<br>
live-migration.<br>
