Registered by Erik Moe on 2013-10-17

Whiteboard

Sep-12-2016(armax): virtually complete, a few gaps still to fill. Optimistically marking complete.

Aug-19-2016(russellb): networking-ovn is working on a driver for this API.

https://review.openstack.org/#/c/356409

July-25-2016(armax): for more details look at work items window. Current snapshot:

https://review.openstack.org/#/q/status:merged+topic:bp/vlan-aware-vms
https://review.openstack.org/#/q/status:open+topic:bp/vlan-aware-vms

Biggest bulk missing - agent side/server integration.

July-5-2016(armax): patches moving along the Gerrit pipeline, more details in Work Items section below.

Apr-20-2016(armax): retargeted, swapped primary assignee and approver. Need nova side taken care of (e.g. for publishing information through metadata server).

Apr-4-2016(armax): Needs new assignee. Will have to assess other resources to bring this to completion.

Mar-3-2106(armax): Moved to Newton. Please ensure you re-submit spec if necessary.

Feb-23-2016(armax): patches started popping up during the month of Feb. This is still most certainly unable to complete in time for Mitaka, but depending on review bandwidth, we can at least address glaring issues. Code available below.

https://review.openstack.org/#/q/status:open+project:openstack/neutron+branch:master+topic:bp/vlan-aware-vms

Feb-09-2016(armax): coding has not yet started. It's unlikely something of this critical mass can make Mitaka. To be resubmitted for Newton.

Jan-18-2016(armax): no major code nor documentation as of today. Chances of getting in Mitaka are getting slim.

Dec-15-2015(armax): latest spec revision is https://review.openstack.org/#/c/243786/, code patches need to be rebooted. There's a dependency on nova.

September-14 (mestery): All patches are WIP and the RC is next week. Thus, this is out of Liberty and hopefully will make Mitaka.

September-8 (mestery): Needs some really beefy reviews this week, we'll re-evaluate at the 9-14 Neutron meeting. Likely moving to Mitaka.

Sept-1-2015(armax): Pushing to L-RC1 - late submission of code patches, and gate issues are a bad combination.
