OSA upgrading Xenial Queens to Bionic Rocky
by Grant Morley 10 Sep '19

10 Sep '19

Hi all, I was wondering if there was a guide for upgrading OpenStack Ansible from Ubuntu 16.04 Queens to Ubuntu 18.04 Rocky? I remember a long time ago there was an etherpad set up for upgrading from 14.04 -> 16.04 but I can't seem to find anything similar for going to 18.04. Annoyingly as we don't have lots of hardware, we are going to have to upgrade in place. If there are any guides that would be much appreciated. Many thanks. -- Grant Morley Cloud Lead, Civo Ltd www.civo.com <https://www.civo.com/>| Signup for an account! <https://www.civo.com/signup>

[neutron][vmware][vsphere] integration
by Ionut Biru 10 Sep '19

10 Sep '19

Hello guys, I'm trying to integrate openstack stein with an already running vmware vsphere cluster. All the documentation that I found explain how do it with distributed switches or port groups but currently in my setup, vmware is using Standard Network. Openstack Stein was deployed using OSA , neutron was configured using ovs and i configured the integrated_bridge to br-int. I tried first to deployed using linux-bridge but when I tried to deployed an instance, neutron returned that only ovs or dvs method is supported. Now when ovs when I'm deploying an instance with network, nova returns an error message: 2019-09-10 10:15:19.010 22443 ERROR nova.compute.manager [instance: d8d1cbb8-5c1c-4b98-9739-bea0668cfaa5] VimFaultException: An error occurred during host configuration. 2019-09-10 10:15:19.010 22443 ERROR nova.compute.manager [instance: d8d1cbb8-5c1c-4b98-9739-bea0668cfaa5] Faults: ['PlatformConfigFault'] How do you guys integrate neutron with vmware vsphere with standard network? Is there a driver that I need to use? -- Ionut Biru - https://fleio.com

Thank you Stackers for five amazing years!
by Chris Hoge 10 Sep '19

10 Sep '19

Hi everyone, After more than nine years working in cloud computing and on OpenStack, I've decided that it is time for a change and will be moving on from the OpenStack Foundation. For the last five years I've had the honor of helping to support this vibrant community, and I'm going to deeply miss being a part of it. OpenStack has been a central part of my life for so long that it's hard to imagine a work life without it. I'm proud to have helped in some small way to create a lasting project and community that has, and will continue to, transform how infrastructure is managed. September 12 will officially be my last day with the OpenStack Foundation. As I make the move away from my responsibilities, I'll be working with community members to help ensure continuity of my efforts. Thank you to everyone for building such an incredible community filled with talented, smart, funny, and kind people. You've built something special here, and we're all better for it. I'll still be involved with open source. If you ever want to get in touch, be it with questions about work I've been involved with or to talk about some exciting new tech or to just catch up over a tasty meal, I'm just a message away in all the usual places. Sincerely, Chris chris(a)hogepodge.com Twitter/IRC/everywhere else: @hogepodge

[keystone] cannot use 'openstack trust list' without admin role
by Francois Scheurer 10 Sep '19

10 Sep '19

Dear Keystone Experts, I have an issue with the openstack client in stage (using Rocky), using a user 'fsc' without 'admin' role and with password auth. 'openstack trust create/show' works. 'openstack trust list' is denied. But keystone policy.json says: "identity:create_trust": "user_id:%(trust.trustor_user_id)s", "identity:list_trusts": "", "identity:list_roles_for_trust": "", "identity:get_role_for_trust": "", "identity:delete_trust": "", "identity:get_trust": "", So "openstack list trusts" is always allowed. In keystone log (I replaced the uid's by names in the ouput below) I see that 'identity:list_trusts()' was actually granted but just after that a_*admin_required()*_ is getting checked and fails... I wonder why... There is also a flag*is_admin_project=True* in the rbac creds for some reason... Any clue? Many thanks in advance! Cheers Francois #openstack --os-cloud stage-fsc trust create --project fscproject --role creator fsc fsc #=> fail because of the names and policy rules, but using uid's it works openstack --os-cloud stage-fsc trust create --project aeac4b07d8b144178c43c65f29fa9dac --role 085180eeaf354426b01908cca8e82792 3e9b1a4fe95048a3b98fb5abebd44f6c 3e9b1a4fe95048a3b98fb5abebd44f6c +--------------------+----------------------------------+ | Field | Value | +--------------------+----------------------------------+ | deleted_at | None | | expires_at | None | | id | e74bcdf125e049c69c2e0ab1b182df5b | | impersonation | False | | project_id | fscproject | | redelegation_count | 0 | | remaining_uses | None | | roles | creator | | trustee_user_id | fsc | | trustor_user_id | fsc | +--------------------+----------------------------------+ openstack --os-cloud stage-fsc trust show e74bcdf125e049c69c2e0ab1b182df5b +--------------------+----------------------------------+ | Field | Value | +--------------------+----------------------------------+ | deleted_at | None | | expires_at | None | | id | e74bcdf125e049c69c2e0ab1b182df5b | | impersonation | False | | project_id | fscproject | | redelegation_count | 0 | | remaining_uses | None | | roles | creator | | trustee_user_id | fsc | | trustor_user_id | fsc | +--------------------+----------------------------------+ #this fails: openstack --os-cloud stage-fsc trust list *You are not authorized to perform the requested action: admin_required.

[ironic] Ironic tempest jobs hitting retry_limit failures
by Clark Boylan 10 Sep '19

10 Sep '19

Hello Ironic, We've noticed that your tempest jobs have been hitting retry_limit failure recently. What this means is we attempted to run the job 3 times but each time the job failed due to "network" problems and Zuul eventually gave up. On further investigation I found that this is happening because the ironic tempest jobs are filling the root disk on rackspace nodes (which have a smaller root / + ephemeral drive mounted at /opt) with libvirt qcow2 images. This seems to cause ansible to fail to operate because it needs to write to /tmp and it thinks there is a "network" error. I've thrown my investigation into a bug for you [0]. It would be great if you could take a look at this as we are effectively spinning our wheels for about 9 hours every time this happens. I did hold the node I used to investigate. If you'd like to dig in yourselves just ask the infra team for access to nodepool node ubuntu-bionic-rax-ord-0011007873. Finally, to help debug these issues in the future I've started adding a cleanup-run playbook [1] which should give us network and disk info (can be expanded if necessary too) for every job when it is done running. Even if the disk is full. [0] https://storyboard.openstack.org/#!/story/2006520 [1] https://review.opendev.org/#/c/681100/ Clark

[devstack][qa][python3] "also install the Python 2 dev library" - still needed?
by Peter Penchev 10 Sep '19

10 Sep '19

Hi, When devstack's `setup_dev_lib` function is invoked and USE_PYTHON3 has been specified, this function tries to also install the development library for Python 2.x, I guess just in case some package has not declared proper Python 3 support or something. It then proceeds to install the Python 3 version of the library and all its dependencies. Unfortunately there is a problem with that, and specifically with script files installed in the system's executable files directory, e.g. /usr/local/bin. The problem appears when some Python library has already been installed for Python 3 (and has installed its script files), but is now installed for Python 2 (overwriting the script files) and is then not forcefully reinstalled for Python 3, since it is already present. Thus, the script files are last modified by the Python 2 library installation and they have a hashbang line saying `python2.x` - so if something then tries to execute them, they will run and use modules and libraries for Python 2 only. We experienced this problem when running the cinderlib tests from Cinder's `playbooks/cinderlib-run.yaml` file - it finds a unit2 executable (installed by the unittest2 library) and runs it, hoping that unit2 will be able to discover and collect the cinderlib tests and load the cinderlib modules. However, since unittest2 has last been installed as a Python 2 library, unit2 runs with Python 2 and fails to locate the cinderlib modules. (Yes, we know that there are other ways to run the cinderlib tests; this message is about the problem exposed by this way of running them) The obvious solution would be to instruct the Python 2 pip to not install script (or other shared) files at all; unfortunately, https://github.com/pypa/pip/issues/3980 ("Option to exclude scripts on install"), detailing a very similar use case ("need it installed for Python 2, but want to use it with Python 3") has been open for almost exactly three years now with no progress. I wonder if I could try to help, but even if this issue is resolved, there will be some time before OpenStack can actually depend on a recent enough version of pip. A horrible workaround would be to find the binary directory before installing the Python 2 library (using something like `pip3.7 show somepackage` and then running some heuristics on the "Location" field), tar'ing it up and then restoring it... but I don't know if I even want to think about this. Another possible way forward would be to consider whether we still want the Python 2 libraries installed - is OpenStack's Python 3 transition reached a far enough stage to assume that any projects that still require Python 2 *and* fail to declare their Python 2 dependencies properly are buggy? To be honest, this seems the most reasonable path for me - drop the "also install the Python 2 libs" code and see what happens. I could try to make this change in a couple of test runs in our third-party Cinder CI system and see if something breaks. Here is a breakdown of what happens, with links to the log of the StorPool third-party CI system for Cinder: https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `stack.sh` invokes `pip_install` for `os-testr` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip_install` sees that we want a Python 3 installation and invokes `pip3.7` to install os-testr. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` wants to install `unittest2` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` has installed `unittest2` - now `/usr/local/bin/unit2` has a hashbang line saying `python3.7` Now this is where it gets, uhm, interesting: https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `setup_dev_lib` is invoked for `os-brick` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `setup_dev_lib`, seeing that we really want a Python 3 installation, decides to install `os-brick` for Python 2 just in case. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip2.7` is invoked to install `os-brick` and its dependencies. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip2.7` decides it wants to install `unittest2`, too. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip2.7` has installed `unittest2`, and now `/usr/local/bin/unit2` has a hasbang line saying `python2.7` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `setup_dev_lib` turns the Python 3 flag back on. https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` is invoked to install `os-brick` https://spfactory.storpool.com/logs/80/639180/35/check/cinder-storpool-temp… `pip3.7` decides (correctly) that it has already installed `unittest2`, so (only partially correctly) it does not need to install it again. Thus `/usr/local/bin/unit2` is left with a hashbang line saying `python2.7`. Thanks for reading this far, I guess :) G'luck, Peter

[nova] Offline Installation of Openstack
by Premdeep S 09 Sep '19

09 Sep '19

Hi Team, Requesting your help on below. We have a requirement to setup Openstack in an isolated infra. We will not be provided with Internet. How can we set it up? 1. Can we have a local repository (Rocky, Universal, etc)created? If so how do we manage it? 2. We have noticed lot of package dependencies while setting up Openstack Infra, so will creating a local repository help in an implementation when we do not have an internet. What is the success rate? Thanks Prem

[manila][ops] Shanghai Forum - Manila Topic Planning
by Tom Barron 09 Sep '19

09 Sep '19

As mentioned several times in the Manila Community Meeting, we have posted an etherpad to brainstorm and gauge interest in topics for the Forum at the upcoming OpenInfra Summit in Shanghai. The point of the Forum sesssions is to get feedback from operators and users on things that need fixing, improvements and enhancements, and more generally about the strategic direction for Manila. So please take a look and update this etherpad with topic ideas and indicate your interest in topics already present if you have an interest in Manila. It doesn't matter whether you contribute to the project or not, or whether you will yourself be attending the Forum: https://etherpad.openstack.org/p/manila-shanghai-forum-brainstorming We will review this etherpad in our community meeting at 1500 UTC on 19 September in #openstack-meeting-alt on Freenode, one day before the Forum proposal deadline. Please feel free to join that meeting to discuss, and in any case please add to the brainstorming deadline before then. Cheers, -- Tom Barron

[keystone] Pre-feature-freeze update
by Colleen Murphy 09 Sep '19

09 Sep '19

I won't be writing a team report since I'm still figuring out which way is up after a week in the desert, but with feature freeze next week I wanted to give a status update on all the in-flight work that is due next week: * System Scope and Default Roles All documented scope[1] and role[2] migrations are in progress. Some are closer to done than others. Since enforce_scope cannot be set to true in keystone.conf until all of them are completed, and since leaving deprecation warnings in the logs for more than two cycles is a very undesirable operator experience, it's essential we complete these by next week. * Application Credential Access Rules This implementation[3] for keystone has been completed for months but the last few patches in the stack are lacking reviews. Client support has been proposed but with the final client release happening next week we will likely not land it until next cycle. * Resource Options and Immutable Resources Resource options[4] and immutable resources[5] are intertwined and the finishing touches are still being applied. Hope to have this completed early next week. * Federated Attributes for Users Support for federated attributes for users[6] is passing CI but needs reviews, it's unclear to me how much has changed since those patches were originally proposed two years ago so it's unfortunate that we're only left with a week to look at them. * Expiring Group Membership There is only a partial implementation proposed for expiring group membership[7] and neither patch is passing CI. This seems to have effectively missed the feature proposal freeze deadline which was a few weeks ago and will not likely make it in this cycle. * CI After skimming the meeting logs I saw the unit test timeout problem was discussed and a temporary workaround was proposed[8]. This sounded like a great idea but it seems that no one implemented it, so I did[9]. Unfortunately this will conflict with all the system-scope/default-roles patches in flight. With how many changes need to go in and how slow it will be with all of them needing to be rechecked and continually making the problem even worse, I propose we go ahead and merge the workaround ASAP and update all the in-flight changes to move the protection tests to the new location. It also appears that the non-voting federation CI broke recently, this will hopefully be fixed by updating the opensuse nodeset[10].

[nova][telemetry] does Telemetry still use the Nova server usage audit log API?
by melanie witt 09 Sep '19

09 Sep '19

Howdy all, TL;DR: I have a question, does the Telemetry service (or any other service) still make use of the server usage audit log API in Nova [1]? Recently I was investigating customer issues where the nova.task_log database table grows infinitely and is never cleaned up [2]. I asked about it today in #openstack-nova [3] and Matt Riedemann explained that the API is toggled via config option [4] and that the Telemetry service is/was the consumer of the API. I found through code inspection that there are no methods for deleting nova.task_log records and am trying to determine what is the best way forward for handling cleanup. Matt mentioned the possibility of deprecating the server usage audit log API altogether, which we might be able to do if no one is using it anymore. So, I was thinking: * If Telemetry is no longer using the server usage audit log API, we deprecate it in Nova and notify deployment tools to stop setting [DEFAULT]/instance_usage_audit = true to prevent further creation of nova.task_log records and recommend manual cleanup by users or * If Telemetry is still using the server usage audit log API, we create a new 'nova-manage db purge_task_log --before <date>' (or similar) command that will hard delete nova.task_log records before a specified date or all if --before is not specified Can anyone shed any light on whether Telemetry, or any other service, still uses the server usage audit log API in Nova? Would we be able to deprecate it? If we can't, what do you think of the nova-manage command idea? I would appreciate hearing your thoughts about it.

[nova][neutron][all][openstack-devs] studying and analysing Openstack developers
by Farida El Zanaty 09 Sep '19

09 Sep '19

Hi! I am Farida El-Zanaty from McGill University. Under the supervision of Prof. Shane McIntosh, my research aims to study design discussions that occur between developers during code reviews. Last year, we published a study about the frequency and types of such discussions that occur in OpenStack Nova and Neutron (http://rebels.ece.mcgill.ca/papers/esem2018_elzanaty.pdf) We are reaching out to OpenStack developers to better understand their perspectives on design discussions during code reviews. Those who are interested can start by participating in our 10-minute survey about their experiences as both the code reviewer and author. Survey participants will be entered into a raffle for a $50 Amazon gift card. Survey: https://forms.gle/Hhn191f6cxF5hVgG8 Thanks for your time, Farida El-Zanaty

Re: [tc] Campaign Question: Treating the Problem, not just the symptoms- Burnout, No Polling, etc

And I would agree that from that standpoint it is open source, and the four opens are good both in letter and in spirit. I would also agree that the academic and other non-profit use of a OpenStack that Jeremy is very compelling and motivating. But the context of much of this thread has been about the experience of the developers making OpenStack. How they come to be in this situation, how they manage their work, who they work with, what drives decisions, etc. (What follows is a ramble. A apologize for not being able to write less. But you did ask so here it goes.) In the context of daily developer experience, things are less clear. They would be more clear and would feel more like open source if I was more frequently collaborating in the creation of code with people who were using OpenStack. But I don't. Most frequently I'm collaborating with people who instead of using OpenStack are helping to make something for other people (with whom they have infrequent collaborative contact) to use OpenStack. For some people this is not the case. For example, many of the people who have been deeply involved with OpenStack infra use OpenStack all the time and also work hard to improve the code of OpenStack. But on a daily basis that isn't my experience. Nor does it feel like the experience of most of the people I tend to collaborate with. Yes, sometimes I will collaborate with someone from CERN to create a feature, but this is rare. Usually I collaborate with people from Intel, VMware, Red Hat, and a variety of Telco vendors. Doing a thing to help an existing customer or hoped for notional customer, both of whom are abstractions at a distance, not humans. This isn't a bad thing. Organizations collaborating in any way is great. But it doesn't _feel_ like "open source" to me. And that feeling is an important factor (I think) in analyzing the motivations people experience when working on OpenStack and the choices they make with regard to how they act in the environment. As someone who has done what could be called open source since long before the term was invented, the common failure of corporate patrons to give maintainability and quality (of product and (critically) the experience of creating it) sufficient attention is a source of a great deal of resentment and internal conflict. I am far too conscious of the necessity to compensate for that failure if I want to feel a sense of well being with what I'm helping to create (both in terms of product and the environment it is being created in). That is: I care enough to try to do what I think is right. In this thread, and the one that started it, we've put forward the "maybe we should just chill" as a bit of an antidote to burnout and overcommitment. While I rationally think that's the right idea, emotionally it is very hard to do and the source of that difficulty is this: OpenStack has constituted itself over the years as the domain of contributing corporations. Many paid contributors for whom working on OpenStack is their job. At the same time we have also been very vocal about being not just open source, but a source of good wisdom (the four opens) on how to do open source well. The latter creates a community I want to believe in. A source of pride. The former creates a conflict of interest, a frequent inability to do the actually right thing for the long term health of the community. A source of shame. Continued pleas to get the corporates to do "open source" well -- that is with correct attention to: * developer experience * maintainability * architectural integrity * deeper/closer ties to user engagement and their satisfaction and thus some akin to "actually open source" -- have fallen on what, if actions speak louder than words, are deaf ears. This creates a conundrum. I've tried a variety of ways out of it. One I'm experimenting with now is realizing that OpenStack really isn't, now, proper open source. And if it is not, then I don't have to care because they don't. > Again I'd be very interested to learn more about your take on what we > can do better. There are two directions to go: Maintain the mode of corporate-contribution-driven development. If this is to be healthy then the corps doing that contribution need to invest far more heavily in general, but especially in the items I've listed above at "correct attention". This would grant the community sufficient resources to evolve out of its aging models for development and governance. You have to have some free space to have the head space to get to new spaces. Start breaking down the corporate-contribution-driven development. Encourage professional openstack devs (like me) to age out of the system and discourage new ones coming in. Encourage feature development from and via users. Feature velocity might drop drastically but they might be features individuals actually use within a few weeks of their release rather than a few years. Some of this latter is already happening. Especially in what some people call the non-core projects; things associated with deployment for example. But in projects like nova we're heavily driven by trying to create a feature base which is predicted to drive sales, either directly or indirectly. And, though opinions and experiences differ, my opinion and experience is that driving sales as a direct factor is anathema to "open source". Indirect? Sure, whatever, if that floats your boat. The proper direct factor is humans. There's a lot more to this than I've stated here, but I hope that gives at least something in answer to the question. -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent

[all][ptl][tc][docs] Develope a code-review practices document
by Trinh Nguyen 09 Sep '19

09 Sep '19

Hi all, I find it's hard sometimes to handle situations in code-review, something likes solving conflicts while not upsetting developers, or suggesting a change to a patchset while still encouraging the committer, etc. I know there are already documents that guide us on how to do a code-review [2] and even projects develope their own procedures but I find they're more about technical issues rather than human communication. Currently reading Google's code-review practices [1] give me some inspiration to develop more human-centric code-review guidelines for OpenStack projects. IMO, it could be a great way to help project teams develop stronger relationship as well as encouraging newcomers. When the document is finalized, I then encourage PTLs to refer to that document in the project's docs. Let me know what you think and I will put a patchset after one or two weeks.

[winstackers][powervmstackers][tc] removing winstackers and PowerVMStackers from TC governance
by Doug Hellmann 09 Sep '19

09 Sep '19

Following the U cycle election there was no candidate for either the winstackers or powervmstackers team PTL role. This is the second cycle in a row where that problem has occurred for both teams, which indicates that the teams are not active in the community. During the TC meeting today [1] we discussed removing the teams from governance, so I have proposed the patches to do that [2][3].

[placement] "now" worklist
by Chris Dent 09 Sep '19

09 Sep '19

As we near the end of a cycle it can be a bit unclear what tasks are relevant or a priority for the placement project. I've made a worklist in storyboard https://storyboard.openstack.org/#!/worklist/754 called "placement now". It gathers stories from the placement group (placement, osc-placement, os-resource-classes, os-traits) that I've tagged with 'pnow' to mean "these are the things we should be concerned with in the near future". This helps to take off the radar anything from the following groups: * Features that will not be considered this cycle. * Anything related to osc-placement (which has already seen its likely last release for this cycle) This leaves placement (the service) bug fixes, and docs. Not yet there is an item for "documenting the new nested provider features", mostly because the story for that has not solidified. Anything that is currently on that list we should finish before the end of the cycle. I hope that having a focused list can help drive that. Thanks. -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent

[mistral] Publish field in workflow tasks
by Ali Abdelal 09 Sep '19

09 Sep '19

Hello, Currently, there are two "publish" fields, one in the task(regular "publish")-the scope is branch and not global, and another under "on-success", “on-error” or “on-complete”. In the current behavior, regular "publish" is ignored if there is "publish" under "on-success", “on-error” or “on-complete” [1]. For example:- (a) version: '2.0' wf1: tasks: t1: publish: res_x1: 1 on-success: publish: branch: res_x2: 2 (b) version: '2.0' wf2: tasks: t1: publish: res_x1: 1 "res_x1" won't be published in (a), but it will in (b). We can either:- 1) Invalidate such syntax. 2) Merge the two publishes together and if there are duplicate keys, there are two options:- a) What takes priority is what's in publish under "on-success" or “on-error” or “on-complete. b) Not allow having a duplicate. What is your opinion? And please tell us if you have other suggestions. [1] https://bugs.launchpad.net/mistral/+bug/1791449

[heat] Resource handling in Heat stacks
by Andreas Florath 09 Sep '19

09 Sep '19

Hello! Can please anybody tell me, if all resources which are created within a Heat stack belong to the stack in the way that all the resources are freed / deleted when the stack is deleted? IMHO all resources which are created during the initial creation or update of a stack, even if they are ephemeral or only internal created, must be deleted when the stack is deleted by OpenStack Heat itself. Correct? My question might see obvious, but I did not find an explicit hint in the documentation stating this. The reason for my question: I have a Heat template which uses two images to create a server (using block_device_mapping_v2). Every time I run an 'openstack stack create' and 'openstack stack delete' cycle one ephemeral volume is left over / gets not deleted. For me this sounds like a problem in OpenStack (Heat). (It looks that this is at least similar to https://review.opendev.org/#/c/341008/ which never made it into master.) Kind regards Andre

[tc][neutron] Supported Linux distributions and their kernel
by Adrian Chiris 08 Sep '19

08 Sep '19

Greetings, I was wondering what is the guideline in regards to which kernels are supported by OpenStack in the various Linux distributions. Looking at [1], Taking for example latest CentOS major (7): Every "minor" version is released with a different kernel version, the oldest being released in 2014 (CentOS 7.0, kernel 3.10.0-123) and the newest released in 2018 (CentOS 7.6, kernel 3.10.0-957) While I understand that OpenStack projects are expected to support all CentOS 7.x releases. Does the same applies for the kernels they originally came out with? The reason I'm asking, is because I was working on doing some cleanup in neutron [2] for a workaround introduced because of an old kernel bug, It is unclear to me if it is safe to introduce this change. [1] https://governance.openstack.org/tc/reference/project-testing-interface.htm… [2] https://review.opendev.org/#/c/677095/ Thanks, Adrian.

Dear Infra Team, We have decided to remove from the Neutron repo the following feature branches: feature/graphql feature/lbaasv2 feature/pecan feature/qos We don't need to preserve any state from these branches. In the case of the first one, no code was merged. The work in the other three branches is already merged into master. Best regards Miguel
