Agenda Today

• Will spend 20 minutes on devstack/bugs/documentation
• Remainder of meeting is on Icehouse Design Summit topics

• devstack ML2 patches
  • Default devstack to ML2: https://bugs.launchpad.net/devstack/+bug/1220745
  • Correctly set L3 service plugin for ML2: https://review.openstack.org/#/c/48522/
• Documentation
  • Need to focus on this now
  • Documentation BP link: https://blueprints.launchpad.net/openstack-manuals/+spec/neutron-ml2-docs
  • ML2 documentation bugs link: https://bugs.launchpad.net/openstack-manuals/+bugs?field.tag=ml2
  • Need to document ML3 with ML2
• Testing and bug fixes
  • Testing of ML2 by everyone would be appreciated
  • We need to find and fix any bugs in the next couple of weeks

• Icehouse Design Summit Topic ideas
  • RPC handling in ML2 for Type and Mechanism Drivers
  • More extensible TypeDrivers for controller-based MechanismDrivers
  • Monolithic Plugin vs. ML2 MechanismDriver - current and future plugins
  • Future Directions for ML2 (orchestration, deployment, management, ...)
  • Migration from deprecated Plugins (openvswitch, linuxbridge) to ML2 - automation?
  • Add support for VXLAN multicast to the OVS agent with newer versions of OVS and Linux kernel.
  • Multi-segment provider network implementations in MechanismDrivers, specifically OVS.

General ML2 Information

Here are the current ml2-specific blueprints for havana:

• https://blueprints.launchpad.net/quantum/+spec/ml2-gre
• https://blueprints.launchpad.net/quantum/+spec/ml2-mechanism-drivers
• https://blueprints.launchpad.net/quantum/+spec/ml2-portbinding
• https://blueprints.launchpad.net/quantum/+spec/ml2-vxlan
• https://blueprints.launchpad.net/quantum/+spec/ml2-multi-segment-api

These tunnel-related blueprints effect the openvswitch and/or linuxbridge agents, and the features should also (or exclusively) be supported (using both agents simultaneously where applicable) by the ml2 plugin:

• https://blueprints.launchpad.net/quantum/+spec/ovs-vxlan-lisp-tunnel
• https://blueprints.launchpad.net/quantum/+spec/openvswitch-kernel-vxlan
• https://blueprints.launchpad.net/quantum/+spec/vxlan-linuxbridge
• https://blueprints.launchpad.net/quantum/+spec/ovs-tunnel-partial-mesh
• https://blueprints.launchpad.net/quantum/+spec/l2-population

These blueprints involve the ml2 MechanismDriver API:

• https://blueprints.launchpad.net/quantum/+spec/tailf-ncs
• https://blueprints.launchpad.net/quantum/+spec/ovsplugin-hardware-devices
