Havana Blueprint Discussions are the Focus Today

BP implementation proposal deadline was last Friday. BP implementation merge deadline is end-of-day next Tuesday, August 3rd. Are the BP implementations in review on-track to be merged? Are there dependencies between them? Are they getting reviewed and updated?

Recently merged:

• Enable GRE and VXLAN with the same ID
  • https://bugs.launchpad.net/neutron/+bug/1196963
  • https://review.openstack.org/#/c/41239/
• ml2-mechanism-driver-subnet-calls
  • https://blueprints.launchpad.net/neutron/+spec/ml2-mechanism-driver-subnet-calls
  • https://review.openstack.org/#/c/43678/
  • IMPORTANT - requires updating mechanism drivers to access Context properties without "()"

Currently in review for H-3:

• ml2-portbinding
  • https://blueprints.launchpad.net/quantum/+spec/ml2-portbinding
  • https://review.openstack.org/#/c/43129/
  • Update very soon with nits fixed, rebased on ml2-mechanism-driver-subnet-calls
  • Remaining items:
    • DB migration
    • Common base class for agent-based mechanism drivers
    • Add agents-db to hyperv agent
    • Binding ports of DHCP, L3, etc. agents needs host-id - have agents set in create_port() vs. map from agent-id using agents-db?
    • Various TODOs and REVISITs
• ml2-multi-segment-api
  • https://blueprints.launchpad.net/neutron/+spec/ml2-multi-segment-api
  • https://review.openstack.org/#/c/43569/
  • Needs reviews before mestery returns
• Arista Driver
  • https://blueprints.launchpad.net/neutron/+spec/arista-ml2-mechanism-driver
  • https://review.openstack.org/#/c/41213/
  • Review items to discuss:
    • Initial version of the driver only supports single segment and single physical network
    • Redundant DB fields facilitating Neutron/EOS sync
    • Port binding integration: https://bugs.launchpad.net/neutron/+bug/1215097
    • README and wiki: https://wiki.openstack.org/wiki/Arista-neutron-ml2-driver
• Cisco Nexus Driver
  • https://blueprints.launchpad.net/quantum/+spec/ml2-md-cisco-nexus
  • https://review.openstack.org/#/c/43196/
  • Needs updated patch - unit test failures, rebase
• Tail-f NCS
  • https://blueprints.launchpad.net/quantum/+spec/tailf-ncs
  • https://review.openstack.org/#/c/37647/
  • Two minor nits in latest update, needs rebase

Others:

• PXI boot ports
  • https://blueprints.launchpad.net/neutron/+spec/pxeboot-ports
  • https://review.openstack.org/#/c/30441/
    • Should add extension to ml2 as well as openvswitch?
• ML2 devstack with additional MechanismDrivers:
  • https://review.openstack.org/#/c/40882/1
  • https://docs.google.com/document/d/1vvfey4SCFA5Ih9e6VUdjnRAVj6YIusfXlbPT8yxVOvY/edit?usp=sharing

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
