Announcements (haleyb)
- We still have a lot of bugs (below)

- If you just need reviews, ping people on irc or post a comment in the review
Topics for Discussion
Live Migration issues with DVR (Swami)
- We have started a discussion on the live migration issue with DVR and how to address it from the neutron side. As a team we need to get consensus on this ideas before we work with the Nova team on this issue.
- https://bugs.launchpad.net/neutron/+bug/1456073 (discussion thread)
- Any updates - Are we all in sync with nova-neutron notifier requirement and also with the changes proposed for the neutron side to address the live migration.
- Live migration will be discussed with the Nova team during the mid-cycle meet-up. This feature discussion is part of the agenda.
- https://review.openstack.org/275073 (Nova change)
- https://review.openstack.org/275420 (Neutron DVR change)

Discuss a plan to address the gate failures (haleyb)
- Current failure rate: https://goo.gl/L1WODG
- Single node check job failure rate has recovered from last week issues, same as non-dvr job as of today.
- Multi-node non-DVR job failures are still over 50% (migrate volume error)
- Multi-node DVR job over 70%
- Filed https://bugs.launchpad.net/bugs/1538387 yesterday (OVS l2pop exception)
- https://review.openstack.org/272986 out for review
- Next noticeable issue: "DVR: Unable to retrieve subnet information for subnet_id"
- Will file bug - looks like get_subnet_for_dvr() call in _bind_centralized_snat_port_on_dvr_subnet() needs to check if subnet_info is not {}
- Filed https://bugs.launchpad.net/bugs/1538387 yesterday (OVS l2pop exception)
- Debug the gate in the current failure state (Identify owners who can own this)
- https://bugs.launchpad.net/neutron/+bug/1515360 - Tempest "SSHTimeout" failures (GOOD TO HAVE) - This patch seem to have some timing issues and so we are seeing more failures for the pings.
- https://review.openstack.org/#/c/247748/ (add debugging code to l3-agent) - Still pings are not consistent with the tempest.
- https://drive.google.com/file/d/0B4kh-7VVPWlPMkdrQWFFdjNsSnM/view?usp=sharing - Logstash failures captured. Any logstash errors can be captured here
