Meeting January 22, 2014

Meeting January 15, 2014

  • Action items from last week:

Meeting January 8, 2014

Meeting Dec 18, 2013

Meeting Dec 11, 2013

  • Action items from last week:
  • Development discussions:
    • blueprint ovs-firewall-driver: progress and technical discussion
      • purpose
      • openvswitch statelessness and security groups frontend API and DB: https://etherpad.openstack.org/p/ovs-firewall-driver-stateless-2
      • ovs_neutron_agent nuances:
        • (1) firewall invoked before agent does anything in C[R]UD operations
        • (2) agent removes all flows at initialization
        • (3) not sure about ovs having atomicity like iptables-restore has (all connections might be dropped/allowed)
      • if extra time, quickly mention:
        • working on adding IPv6 flows
        • working on adding multiple ports in range (try port bitmask or N flows per N ports?)
        • of course, need to add unit/integration tests; if someone wants to help on integration tests, that would be good if that's possible
        • neutron-rootwrap-xen-dom0 bugs: https://bugs.launchpad.net/neutron/+bug/1185872/comments/3, https://bugs.launchpad.net/neutron/+bug/1259748
        • other network types: should work as-is since the tunnel OVS flows just pass it to the integration bridge where firewall flows live, but test environment not setup to do so
        • table, priority coordination: ok for now to be hard-coded in Neutron, but will need an abstraction in the future possibly

Meeting Dec 4, 2013

  • Action items from last week:
    • mestery: follow up with the ci team to determine if multi-node testing can be performed in the gate.
    • asomya: provide review comments for TypeDriver patch from ZangMingJie.
  • Development issues
    • VLAN availability issue during delete_port_postcommit()
  • Testing
    • Additional unit tests needed
    • Multi-node devstack based gate testing
    • Tempest tests
      • Scenario tests around ML2+LinuxBridge
      • Scenario tests around ML2+L2 Population
      • Scenario tests around ML2+OpenDaylight (coming soon)
    • Vendor Tempest testing discussion for MechanismDrivers
  • Revisit "Modular L2 TypeDriver extra port information"

Previous Agenda

  • 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.
    • Additional provider network attributes for controller-based plugins such as ODL for networks created outside of Neutron.

Icehouse ML2 work for reference


Previous Meeting Logs

General ML2 Information

Here are the current ml2-specific blueprints for havana:

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:

These blueprints involve the ml2 MechanismDriver API:
