  • Open Discussion

Meeting March 16, 2016

  • Announcements
  • port binding with port owned by router
  • Simulate portbinding on migration target host (scheuran)
    • Use Case: Migration cross l2 agents, migration with macvtap l2 agent --> In both cases nova needs to know the portbinding information that should be used on the migration target before migration has started (in nova pre_live_migration) and before port has been bound. This information is required to trigger the correct vif-plug action on the target and to modify the libvirt domain.xml accordingly
    • Approach: Some new api call is required, which simulates the portbinding for the target host and returns this information
    • This is just as a heads up - I try to come up with more details in the next meeting (23rd of March)

  • Open Discussion

Meeting April 8, 2015

  • Action Items from Last week
  • Mechanism drivers and DVR discussion (rkukura)
    • Have made good (but slow) progress on DVR port binding schema and logic cleanup
    • Discovered no current unit tests cover critical DVR port binding logic, so adding them as separate patch against current code, then will ensure they don't break in dependent cleanup patch
      • Extending test_port_binding to exercise update_dvr_port_binding, get_device_details, etc. for DVR ports, utilizing existing PortContext state asserts in mechanism_test MD
      • Hoped to get at least the new UTs into kilo, but probably too late, but can back-port to kilo
    • Discovered several issues (inconsistencies in per-host vs. host-independent state in PortContext) that would seem to break ToR switch MDs that need to track binding state per host:
      • When committing DVR port binding, PortContext passed to update_port methods has new binding:vif_type and binding:vif_details for the bound host, but shows 'distributed' for previous binding:vif_type instead of 'unbound' like for normal ports, and empty strings for current or previous binding:host_id - propose to make these work like for non-DVR ports
      • When updating DVR port's status, PortContext currently shows 'distributed' for binding:vif_type and empty string for host, but has binding_levels, etc., for the specific host - could change this to reflect host-specific state, or to only be called when port's status changes and reflect non-host-specific state
    • Issues to discuss
      • Has anyone tested their MDs with DVR?
      • Has anyone run into these (or other) issues?
      • Is back-porting these sorts of behavioral fixes to kilo acceptable?
      • Do we have consensus on making update_port methods reflect per-host state when committing DVR port binding?
      • Do we prefer to make update_port methods reflect per-host state or only host-independent state when changing DVR port status, or do we need separate updates for each?

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:
