Categorized Bugs
Gate Test Failures
Functional test failures seen in Gate.
RFE
- https://bugs.launchpad.net/neutron/+bug/1563879 (RFE)
- https://bugs.launchpad.net/neutron/+bug/1557290 (RFE)
- https://bugs.launchpad.net/neutron/+bug/1583694 (RFE)
- https://review.openstack.org/#/c/320669/ (WIP)(Server side patch)
- https://review.openstack.org/#/c/323618/ (WIP)(Agent side patch)
Existing Functionality Broken Bugs
- https://bugs.launchpad.net/neutron/+bug/1590041 (SHOULD-FIX) - Regression, snat_namespace object creation ahead of time does not solve some external_gateway_update condition.
- 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) - Floating ip 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.
- https://bugs.launchpad.net/neutron/+bug/1571676 (MUST FIX) - Static routes not added to FloatingIP Namespace.
- https://review.openstack.org/#/c/308068/
- This approach can't really work because adding a static route in the FIP namespace for one tenant could impact traffic for another tenant.
- https://bugs.launchpad.net/neutron/+bug/1564776 - (MUST FIX) (Snat Namespace error when namespace deleted)
- https://bugs.launchpad.net/neutron/+bug/1564757 - (MUST FIX) (FloatingIPError while agent restarts)

- https://review.openstack.org/#/c/277657/ (Patch) - Needs update to create a better abstraction that allows clients to get the namespace for the right part of the router.
- https://bugs.launchpad.net/neutron/+bug/1456073 (High) - Block Migration with FIP breaks with DVR (MUST FIX)
- https://review.openstack.org/275073 (Nova side change) - Needs review
- https://review.openstack.org/#/c/286855/ (Tempest change) - Needs work - must merge before Nova patch
- https://review.openstack.org/275420 (Merged) - Neutron Server side DVR change

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 are more when compared to neutron full job.
- 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)
- Bugs in Nova:
- Old bug to help in debugging the gate
- https://bugs.launchpad.net/neutron/+bug/1515360 - Tempest "SSHTimeout" failures (only for debugging)
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. Bugs are removed from list as they merge.
Open Discussion
Need to escalate the nova patch for the live migration. Since we have the tempest test running right now, we need someone from the nova team to take a look at the nova live migration patch.
