All DVR bugs should be tagged and listed here: https://bugs.launchpad.net/neutron/+bugs?field.tag=l3-dvr-backlog

New Bugs this week

• https://bugs.launchpad.net/neutron/+bug/1583266 (SHOULD FIX) - watch_log_file=True causes fip to slow down. Symptom seen more with DVR routers.
• https://bugs.launchpad.net/neutron/+bug/1585165 (SHOULD FIX) - Floatingip not reachable after VM live migration (Seen in Liberty with DVR) - Seems to me like a duplicate but should triage it more on the symptoms.

Performance/Scalability

Gate failures (haleyb)

• Current failure rate: https://goo.gl/L1WODG
  • Functional test failures seen in the Check queue, root cause yet to be identified.
  • Single node check job failure rates stabilized 3/14 and are below 6% (non-DVR and DVR)
  • Multi-node check job failure rate have gone up from last week
    • Bugs in Nova:
      • https://bugs.launchpad.net/nova/+bug/1524898 (Volume based live migration aborted unexpectedly)
      • https://bugs.launchpad.net/nova/+bug/1535232 (live-migration ci failure on nfs shared storage)
• 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://drive.google.com/file/d/0B4kh-7VVPWlPMkdrQWFFdjNsSnM/view?usp=sharing - Logstash failures captured. Any logstash errors can be captured here

Stable backports (haleyb)

Ihar created a page tracking all the potential backports from Mitaka to the stable releases. I have been going through it with the help of Swami to get stable/liberty, well, more stable
