[all][tc] What happened in OpenStack Governance recently
by Rico Lin 14 Oct '19

14 Oct '19

Hello everyone, Here are a few things that happened recently: - *We've got the last volley of new PTLs!* Lucian Petrut for winstackers and Nicholas Bock for Designate. Congratulations! *- Rico Lin is now the Vice-chair of the TC.* - As mentioned in [1], *we will have two `Meet the project leaders` events* during the Shanghai summit. It will be nice if OpenStack PTLs, SIG Chairs, TC members, core reviewers, UC members, interested in join. You can signup in [2] to let others know you're coming. And if you think you might be part of this or you would like to meet any of them. Yes! you should come! -* We're open for goal idea*, so add it in [3] if you have any. We also looking for V cycle goal as well. And here's some backlog [4] if you're interested to be a champion of it. - At this point you should already know, *the newest OpenStack User Survey results are already out *[8]. So analysis it and make decisions accordingly (assume those questions are essential for team dicisions). - *The Shanghai PTG schedule is finalized*. Please check [7] for more detail on each forum. We hope we can have users, operators, and developers all together to collaborate and make more successful and valuable outcome from each forum. So please join! - Big thanks to our release team, *Train final releases for cycle-with-rc projects is right around the corner* [9]. - Our official meeting happened on October 10, as announced on the ML. We decided the following: - As one of meeting actions, a ML `[tc] Status update on naming our next releases` [6] is out (Thanks to Thierry). If you would like to give your review/feedback before proposals (mentioned in that mail) gets a majority of TC votes, now is the time. As always your review and feedback matter. - Summit and PTG are near, currently, Summit presentations and Forum sessions [7] are released. At this point, teams (which plan to join PTG) should start planning for their PTG topics and formats. So please help with teams to be prepared. For TC PTG, please propose topics before October 17, so we will have two weeks to discuss, finalize, and prepare. - V cycle goal discussion will be more asynchronously, more ML for U and V cycle goal process will be out soon. - Thanks for the effort of swift team, current python 3 support for swift is good. This makes OpenStack more ready for python 3 first. - There will be a forum [5] for large scale SIG, so if you're interested, please join (we hope to have more large scale users join to provide hands and feedbacks) so we can make OpenStack a better place for large scale.

[oslo] New courtesy ping list for Ussuri
by Ben Nemec 14 Oct '19

14 Oct '19

As we discussed at the beginning of the cycle, I'll be clearing the current ping list in the next few weeks. This is to prevent courtesy pinging people who are no longer active on the project. If you wish to continue receiving courtesy pings at the start of the Oslo meeting please add yourself to the new list on the agenda template [0]. Note that the new list is above the template, called "Courtesy ping list for Ussuri". If you add yourself again to the end of the existing list I'll assume you want to be left on though. :-) Thanks. -Ben 0: https://wiki.openstack.org/wiki/Meetings/Oslo#Agenda_Template

[watcher] Thesis on improving Watcher and collaborating with OpenStack community
by info＠dantalion.nl 14 Oct '19

14 Oct '19

Hello everyone, I am a Dutch student at the Amsterdam University of Applied Sciences (AUAS) and have recently finished my thesis. My thesis was written on improvements that were made to OpenStack Watcher between February and Juli of 2019. Specifically, many of these improvements were written to aid CERN in deploying Watcher. In addition, the thesis describes methods of collaboration and engaging in communities as well as evaluating strengths and weaknesses of communties. Since the thesis primarily resolves around OpenStack I would like to share it with the community as well. Please find the thesis attached to this email. Any feedback, remarks, future advice or other responses are appreciated. Kind regards, Corne Lukken (Dantali0n)

[nova][all] Roadmap for dropping Python 2 support
by Stephen Finucane 14 Oct '19

14 Oct '19

The time has come. Train is almost out the door and we're already well into Ussuri planning and work. We agreed some time ago that this cycle was the right one to drop support for Python 2.7 [1] and to that effect I've proposed a patch to do just this in nova [2]. However, I have noticed a large number of the third party CIs are failing on this patch. This is because they are still testing with Python 2 and the patch marks nova as only supporting Python 3. As you can see in that patch, the effort to switch things over is not that significant, and I'd ask that any owners of third party CIs prioritise work to switch these things over in the next few weeks leading up to the PTG so we can merge this change as soon as possible. Please reach out on IRC if you have any concerns or questions. Cheers, Stephen [1] https://governance.openstack.org/tc/resolutions/20180529-python2-deprecatio… [2] https://review.opendev.org/#/c/687954/

[tc] Status update on naming our next releases
by Thierry Carrez 14 Oct '19

14 Oct '19

Hi, Following last week TC meeting, I took the action to summarize the situation and way forward of naming releases. Naming our U release was a bit of a painful process, mostly due to the subjectivity of the process, combined with a difficult combination of letter vs. naming criteria. It triggered proposals to change the naming process and/or criteria, as we expect similar difficulties with the rest of the alphabet. We did a first round of proposals that covered the V-Z part of the alphabet. A Condorcet poll was run to select the best options. The two best ones were then run in a new Condorcet poll against "keep things the same", and the result was a draw. It was a good indication that the TC membership found none of the proposals on the table was significantly better than keeping things the same, and therefore no change was effected. That said, it does not mean we should stop proposing new models, as the current system is flawed: its subjectivity combined with a popularity contest creates problems, and its criteria (strongly tied to event locations) will not work well in the future as we work to reduce the number of global events we run while increasing the number of local events. The way forward is as follows: proposals can still be made, but they should address "any foreseeable future". That means they need to explain how they will name the V-Z releases, but also how they will roll over past Z. TC members should rollcall-vote +1 on those proposals if they think they are better than keeping things the same. They can rollcall-vote -1 on the proposals for which they think keeping things the same would be better. If one proposal gets a majority of votes (seven +1s), then after the usual grace period of 3 calendar days, it should be approved (unless a competing proposals gathers *more* positive votes in the mean time). There is no deadline for proposing, even after one such proposal is approved. Those things can always be changed in the future. However I personally don't think we should change naming systems too often, because they are only fun if they become some sort of tradition. We currently have three proposals up: Cities with 100,000+ inhabitants, TC-only poll: https://review.opendev.org/#/c/677745/ Vancouver, then words present in movie quotes about "release": https://review.opendev.org/#/c/684688/ Vancouver, then cities with 100,000+ inhabitants, community poll: https://review.opendev.org/#/c/687764/ Cheers, -- Thierry Carrez (ttx)

[kolla] Support for removing previously enabled services..
by Laurent Dumont 14 Oct '19

14 Oct '19

Hey everyone, I'm pretty sure I know the answer but are there any support within Kolla itself to disable Services that we're previously enabled. For example, I was testing the Skydive Agent/Analyzer combo till I realized that it was using about 90-100% of the CPUs or computes and controllers. [image: image.png] Re-running Kolla with reconfigure but with Service set to "No" didn't remove the containers. I had to remove the containers after the reconfigure finished. This is Kolla 8.0.1 with a Stein install. Thanks!

[goals][IPv6-Only Deployments and Testing] Update
by Ghanshyam Mann 14 Oct '19

14 Oct '19

Hello Everyone, Below is the updated on IPv6 goal. All the projects have the ipv6 job patch proposed now. Next step is to review then as per mentioned guidelines below or help in debugging the failure. As stable/train is already cut for all the projects, we will keep merging the remaining projects listed below in Ussuri release. If your project is listed below, check the project patch and help in review/debug failure. Summary: The projects waiting for IPv6 job patch to merge: If patch is failing, help me to debug that otherwise review and merge. * Barbican * Tricircle * Vitrage * Zaqar * Glance * Monasca * Neutron stadium projects (added a more generic job for all. need debugging as few tests failing- https://review.opendev.org/#/c/686043/) * Qinling * Sahara * Searchlight * Senlin * Tacker * Ec2-Api * Freezer * Heat * Ironic * Karbor * kuryr-kubernetes (not yet ready for IPv6. as per IRC chat with dulek, IPv6 support is planned for ussuri cycle - https://review.opendev.org/#/c/682531/) * Magnum * Masakari * Mistral * Octavia (johnsom is working on this) Storyboard: ========= - https://storyboard.openstack.org/#!/story/2005477 IPv6 missing support found: ===================== 1. https://review.opendev.org/#/c/673397/ 2. https://review.opendev.org/#/c/673449/ 3. https://review.opendev.org/#/c/677524/ There are few more but need to be tracked. How you can help: ============== - Each project needs to look for and review the ipv6 job patch. - Verify it works fine on ipv6 and no ipv4 used in conf etc - Any other specific scenario needs to be added as part of project IPv6 verification. - Help on debugging and fix the bug in IPv6 job is failing. Everything related to this goal can be found under this topic: Topic: https://review.opendev.org/#/q/topic:ipv6-only-deployment-and-testing+(stat… How to define and run new IPv6 Job on project side: ======================================= - I prepared a wiki page to describe this section - https://wiki.openstack.org/wiki/Goal-IPv6-only-deployments-and-testing Review suggestion: ============== - Main goal of these jobs will be whether your service is able to listen on IPv6 and can communicate to any other services either OpenStack or DB or rabbitmq etc on IPv6 or not. So check your proposed job with that point of view. If anything missing, comment on patch. - One example was - I missed to configure novnc address to IPv6- https://review.opendev.org/#/c/672493/ - base script as part of 'devstack-tempest-ipv6' will do basic checks for endpoints on IPv6 and some devstack var setting. But if your project needs more specific verification then it can be added in project side job as post-run playbooks as described in wiki page[1].

[kolla][tacker][glance] Deployment of Tacker Train (VNF CSAR packages issues)
by Radosław Piliszek 12 Oct '19

12 Oct '19

Hello Tackers! Some time ago I reported a bug in Kolla-Ansible Tacker deployment [1] Eduardo (thanks!) did some debugging to discover that you started requiring internal Glance configuration for Tacker to make it use the local filesystem via the filestore backend (internally in Tacker, not via the deployed Glance) [2] This makes us, Koalas, wonder how to approach a proper production deployment of Tacker. Tacker docs have not been updated regarding this new feature and following them may result in broken Tacker deployment (as we have now). We are especially interested in how to deal with multinode Tacker deployment. Do these new paths require any synchronization? [1] https://bugs.launchpad.net/kolla-ansible/+bug/1845142 [2] https://review.opendev.org/#/c/684275/2/ansible/roles/tacker/templates/tack… Kind regards, Radek

[neutron][security group][IPv6] IPv6 ICMPv6 port security in security group
by Xing Zhang 11 Oct '19

11 Oct '19

Hi all, When using neutron on CentOS 7 with OVSHybridIptablesFirewallDriver, create a vm with IPv4/IPv6 dual stack port, then remove all security group, we can get response with ping dhcp or router using IPv6 address in vm, while IPv4 can't. IPv6 works different with IPv4 in some cases and some useful function must work with ICMPv6 like NDP, NS, NA. Checking these two links below, neutron only drop IPv6 RA from vm, and allow all ICMPv6 ICMPv6 Type 128 Echo Request and Type 129 Echo Reply are allowed by default. Should we try to restrict ICMPv6 some types or there are some considerations and just follow ITEF 4890? IETF 4890 [section 4.3.2. Traffic That Normally Should Not Be Dropped] mentioned that: As discussed in Section 3.2 <https://tools.ietf.org/html/rfc4890#section-3.2>, the risks from port scanning in an IPv6 network are much less severe, and it is not necessary to filter IPv6 Echo Request messages.

Port creation times out for some VMs in large group
by Albert Braden 11 Oct '19

11 Oct '19

When I create 100 VMs in our prod cluster: openstack server create --flavor s1.tiny --network it-network --image cirros-0.4.0-x86_64 --min 100 --max 100 alberttest Most of them build successfully in about a minute. 5 or 10 will stay in BUILD status for 5 minutes and then fail with " BuildAbortException: Build of instance <UUID> aborted: Failed to allocate the network(s), not rescheduling." If I build smaller numbers, I see less failures, and no failures if I build one at a time. This does not happen in dev or QA; it appears that we are exhausting a resource in prod. I tried reducing various config values in dev but am not able to duplicate the issue. The neutron servers don't appear to be overloaded during the failure. What config variables should I be looking at? Here are the relevant log entries from the HV: 2019-09-26 10:10:43.001 57008 INFO os_vif [req-dea54d9a-3f3e-4d47-b901-a4f41b1947a8 d28c3871f61e4c8c8f8c7600417f7b14 e9621e3b105245ba8660f434ab21016c - default 4fb72165eee4468e8033cdc7d506ddf0] Successfully plugged vif VIFBridge(active=False,address=fa:16:3e:8b:45:07,bridge_name='brq49cbe55d-51',has_traffic_filtering=True,id=18f4e419-b19c-4b62-b6e4-152ec78e72bc,network=Network(49cbe55d-5188-4183-b5ad-e65f9b46f8f2),plugin='linux_bridge',port_profile=<?>,preserve_on_delete=False,vif_name='tap18f4e419-b1') 2019-09-26 10:15:44.029 57008 WARNING nova.virt.libvirt.driver [req-dea54d9a-3f3e-4d47-b901-a4f41b1947a8 d28c3871f61e4c8c8f8c7600417f7b14 e9621e3b105245ba8660f434ab21016c - default 4fb72165eee4468e8033cdc7d506ddf0] [instance: dc58f154-00f9-4c45-8986-94b10821cbc9] Timeout waiting for [('network-vif-plugged', u'18f4e419-b19c-4b62-b6e4-152ec78e72bc')] for instance with vm_state building and task_state spawning.: Timeout: 300 seconds More logs and data: http://paste.openstack.org/show/779524/

[keystone][edge][k8s] Keystone - StarlingX integration feedback
by Ildiko Vancsa 11 Oct '19

11 Oct '19

Hi, I wanted to point you to a thread that’s just started on the edge-computing mailing list: http://lists.openstack.org/pipermail/edge-computing/2019-October/000642.html The mail contains information about a use case that StarlingX has to use Keystone integrated with Kubernetes which I believe is valuable information to the Keystone team to see if there are any items to discuss further/fix/implement. Thanks, Ildikó

[Openstack] FOSDEM 2020 Virtualization & IaaS Devroom CfP
by Piotr Kliczewski 11 Oct '19

11 Oct '19

We are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2020, to be hosted on February 1st 2020. This year will mark FOSDEM’s 20th anniversary as one of the longest-running free and open source software developer events, attracting thousands of developers and users from all over the world. FOSDEM will be held once again in Brussels, Belgium, on February 1st & 2nd, 2020. This devroom is a collaborative effort, and is organized by dedicated folks from projects such as OpenStack, Xen Project, oVirt, QEMU, KVM, and Foreman. We would like to invite all those who are involved in these fields to submit your proposals by December 1st, 2019. About the Devroom The Virtualization & IaaS devroom will feature session topics such as open source hypervisors and virtual machine managers such as Xen Project, KVM, bhyve, and VirtualBox, and Infrastructure-as-a-Service projects such as KubeVirt, Apache CloudStack, OpenStack, oVirt, QEMU and OpenNebula. This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM. Important Dates Submission deadline: 1 December 2019 Acceptance notifications: 10 December 2019 Final schedule announcement: 15th December 2019 Devroom: 1st February 2020 Submit Your Proposal All submissions must be made via the Pentabarf event planning site[1]. If you have not used Pentabarf before, you will need to create an account. If you submitted proposals for FOSDEM in previous years, you can use your existing account. After creating the account, select Create Event to start the submission process. Make sure to select Virtualization and IaaS devroom from the Track list. Please fill out all the required fields, and provide a meaningful abstract and description of your proposed session. Submission Guidelines We expect more proposals than we can possibly accept, so it is vitally important that you submit your proposal on or before the deadline. Late submissions are unlikely to be considered. All presentation slots are 30 minutes, with 20 minutes planned for presentations, and 10 minutes for Q&A. All presentations will be recorded and made available under Creative Commons licenses. In the Submission notes field, please indicate that you agree that your presentation will be licensed under the CC-By-SA-4.0 or CC-By-4.0 license and that you agree to have your presentation recorded. For example: "If my presentation is accepted for FOSDEM, I hereby agree to license all recordings, slides, and other associated materials under the Creative Commons Attribution Share-Alike 4.0 International License. Sincerely, <NAME>." In the Submission notes field, please also confirm that if your talk is accepted, you will be able to attend FOSDEM and deliver your presentation. We will not consider proposals from prospective speakers who are unsure whether they will be able to secure funds for travel and lodging to attend FOSDEM. (Sadly, we are not able to offer travel funding for prospective speakers.) Submission Guidelines Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. The number of newcomer session slots is limited, so we will probably not be able to accept all applications. You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email our devroom mailing list[2] and we will try to help you. How to Apply In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. Code of Conduct Following the release of the updated code of conduct for FOSDEM, we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email us and we will do our best to assist you. Call for Volunteers We are also looking for volunteers to help run the devroom. We need assistance watching time for the speakers, and helping with video for the devroom. Please contact devroom mailing list [2] for more information. Questions? If you have any questions about this devroom, please send your questions to our devroom mailing list. You can also subscribe to the list to receive updates about important dates, session announcements, and to connect with other attendees. See you all at FOSDEM!

[release] Release countdown for week R-0, October 14-18
by Sean McGinnis 10 Oct '19

10 Oct '19

Development Focus ----------------- We will be releasing the coordinated OpenStack Train release next week, on Wednesday October 16th. Thanks to everyone involved in the Train cycle! We are now in pre-release freeze, so no new deliverable will be created until final release, unless a release-critical regression is spotted. Otherwise, teams attending the PTG in Shanghai should start to plan what they will be discussing there, by creating and filling team etherpads. You can find the list of etherpads at: http://ptg.openstack.org/etherpads.html General Information ------------------- On release day, the release team will produce final versions of deliverables following the cycle-with-rc release model, by re-tagging the commit used for the last RC. A patch doing just that will be proposed. PTLs and release liaisons should watch for that final release patch from the release team. While not required, we would appreciate having an ack from each team before we approve it on the 16th. Upcoming Deadlines & Dates -------------------------- Final Train release: October 16 Forum+PTG at Shanghai summit: November 4

Networking-vpp 19.08.1 for VPP 19.08.1 is now available
by Naveen Joy (najoy) 10 Oct '19

10 Oct '19

Hello All, We'd like to invite you to try out Networking-vpp 19.08.1. As many of you may already know, VPP is a fast user space forwarder based on the DPDK toolkit. VPP uses vector packet processing algorithms to minimize the CPU time spent on each packet to maximize throughput. Networking-vpp is a ML2 mechanism driver that controls VPP on your control and compute hosts to provide fast L2 forwarding under Neutron. This latest version of Networking-vpp is updated to work with VPP 19.08.1 In this release, we've worked on the below updates: - We've added ERSPAN support for Tap-as-a-Service (TaaS). Since ERSPAN provides remote port mirroring, you can now mirror your OpenStack traffic to a destination outside of OpenStack or to a remote OpenStack VM. This is a customized version of OpenStack TaaS. We will be working with the community to push our custom TaaS extensions upstream. In the meantime, you can access our modified TaaS code here[2]. For further info on installation and usage, you can read the TaaS-README[3]. - We've updated the code to be compatible with VPP 19.08 & 19.08.1 API changes. - We've updated the unit test framework to support python3.5 onwards. - We've added security-group support for Trunk subports. We've added support for neutron trunk_details extension. - We've fixed some bugs in our Trunk and L3 plugins that caused a race condition during port binding. - We've migrated our repo from OpenStack to OpenDev. - A recent change in nova caused live migration to fail for instances with NUMA characteristics. We've found that this is a limitation in nova and not VPP/Networking-vpp. It is still possible to use live migration with VPP/Networking-vpp. Please refer to the README[1] for further details. - We've been doing the usual round of bug fixes and updates. The code will work with VPP 19.08.1 and has been updated to keep up with Neutron Rocky and Stein. The README [1] explains how you can try out VPP with Networking-vpp using Devstack: the Devstack plugin will deploy the mechanism driver and VPP and should give you a working system with a minimum of hassle. We will be continuing our development for VPP's 20.01 release. We welcome anyone who would like to come help us. -- Naveen, Ian & Jerome [1] https://opendev.org/x/networking-vpp/src/branch/master/README.rst [2] https://github.com/jbeuque/tap-as-a-service [3] https://opendev.org/x/networking-vpp/src/branch/master/README_taas.txt

[charms] placement charm
by Corey Bryant 10 Oct '19

10 Oct '19

Hi All, I'd like to see if I can get some input on the current state of the Placement API split. For some background, the nova placement API was removed from nova in train, and it's been split into its own project. It's mostly just a basic API charm. The tricky part is the migration of tables from the nova_api database to the placement database. Code is located at: https://github.com/coreycb/charm-placement https://github.com/coreycb/charm-interface-placement https://review.opendev.org/#/q/topic:charms-train-placement+(status:open+OR… Test scenarios I've been testing with: 1) deploy nova-cc et al train, configure keystonev3, deploy instance 2) deploy nova-cc et al stein, configure keystonev3, deploy instance 1, deploy placement train, deploy instance 2, upgrade nova-cc to train, deploy instance 3 There is currently an issue with the second test scenario where instance 2 creation errors because nova-scheduler can't find a valid placement candidate (not sure of the exact error atm). However if I delete instance 1 before creating instance 2 it is created successfully. It feels like a DB related issue but I'm really not sure so I'll keep digging. Thanks! Corey
