[Neutron][vxlan][nsx-v]
by Ignazio Cassano 16 Sep '19

16 Sep '19

Hello, I have a vmware vcenter installatiom with nsx-v and an openstack installation with kvm and openvswitch. I am looking for a method for realizing a vxlan shared between nsx-v and openvswitch. I know vmware released nsx-t but I prefer to use an opensource solution. Anyone could suggest a solution? Thanks Ignazio

[dev] [glance] proposal for S3 store driver re-support as galnce_store backend
by Naohiro Sameshima 16 Sep '19

16 Sep '19

Hi all, I know that glance_store had supported S3 backend until version OpenStack Mitaka, and it has already been removed due to lack of maintainers [1][2]. I started refactoring the S3 driver to work with version OpenStack Stein and recently completed it. (e.g. Add Multi Store Support, Using the latest AWS SDK) So, it would be great if glance_store could support the S3 driver again. However, I'm not familiar with the procedure for that. Would it be possible to discuss this? Thanks, Naohiro [1] https://docs.openstack.org/releasenotes/glance/newton.html [2] https://opendev.org/openstack/glance_store/src/branch/master/releasenotes/n…

[placement] update 19-35
by Chris Dent 16 Sep '19

16 Sep '19

HTML: https://anticdent.org/placement-update-19-36.html Here's placement update 19-36. There won't be one next week, I will be away. Because of my forthcoming "less time available for OpenStack" I will also be stopping these updates at some point in the next month or so so I can focus the limited time I will have on reviewing and coding. There will be at least one more. # Most Important The big news this week is that after returning from a trip (that meant he was away during the nomination period) Tetsuro has stepped up to be the PTL for placement in Ussuri. Thanks very much to him for taking this up, I'm sure he will be excellent. We need to work on useful documentation for the features developed this cycle. I've also made a [now worklist](https://storyboard.openstack.org/#!/worklist/754) in StoryBoard to draw attention to placement project stories that are relevant to the next few weeks, making it easier to ignore those that are not relevant now, but may be later. # Stories/Bugs (Numbers in () are the change since the last pupdate.) There are 23 (-1) stories in [the placement group](https://storyboard.openstack.org/#!/project_group/placement). 0 (0) are [untagged](https://storyboard.openstack.org/#!/worklist/580). 5 (0) are [bugs](https://storyboard.openstack.org/#!/worklist/574). 4 (0) are [cleanups](https://storyboard.openstack.org/#!/worklist/575). 10 (-1) are [rfes](https://storyboard.openstack.org/#!/worklist/594). 5 (1) are [docs](https://storyboard.openstack.org/#!/worklist/637). If you're interested in helping out with placement, those stories are good places to look. * Placement related nova [bugs not yet in progress](https://goo.gl/TgiPXb) on launchpad: 17 (0). * Placement related nova [in progress bugs](https://goo.gl/vzGGDQ) on launchpad: 6 (0). # osc-placement * <https://review.opendev.org/666542> Add support for multiple member_of. There's been some useful discussion about how to achieve this, and a consensus has emerged on how to get the best results. # Main Themes ## Consumer Types Adding a type to consumers will allow them to be grouped for various purposes, including quota accounting. * <https://review.opendev.org/#/q/topic:bp/support-consumer-types> This has some good comments on it from melwitt. I'm going to be away next week, so if someone else would like to address them that would be great. If it is deemed fit to merge, we should, despite feature freeze passing, since we haven't had much churn lately. If it doesn't make it in Train, that's fine too. The goal is to have it ready for Nova in Ussuri as early as possible. ## Cleanup Cleanup is an overarching theme related to improving documentation, performance and the maintainability of the code. The changes we are making this cycle are fairly complex to use and are fairly complex to write, so it is good that we're going to have plenty of time to clean and clarify all these things. Performance related explorations continue: * <https://review.opendev.org/#/c/679385/> Refactor initialization of research context. This puts the code that might cause an exit earlier in the process so we can avoid useless work. One outcome of the performance work needs to be something like a _Deployment Considerations_ document to help people choose how to tweak their placement deployment to match their needs. The simple answer is use more web servers and more database servers, but that's often very wasteful. * <https://review.opendev.org/#/q/owner:"Chris+Dent+%253Ccdent%2540anticdent.org%253E"+topic:build-pdf-docs> These are the patches for meeting the build pdf docs goal for the various placement projects. # Other Placement Miscellaneous changes can be found in [the usual place](https://review.opendev.org/#/q/project:openstack/placement+status:op…. There are three [os-traits changes](https://review.opendev.org/#/q/project:openstack/os-traits+status:… being discussed. And two [os-resource-classes changes](https://review.opendev.org/#/q/project:openstack/os-resource-class…. The latter are docs-related. # Other Service Users New reviews are added to the end of the list. Reviews that haven't had attention in a long time (boo!) or have merged or approved (yay!) are removed. * <https://review.opendev.org/662229> helm: add placement chart * <https://review.opendev.org/670112> Nova: WIP: Add a placement audit command * <https://review.opendev.org/670696> tempest: Add placement API methods for testing routed provider nets * <https://review.opendev.org/#/q/topic:bp/cross-cell-resize> Nova: cross cell resize * <https://review.opendev.org/674524> Nova: Scheduler translate properties to traits * <https://review.opendev.org/623558> Nova: single pass instance info fetch in host manager * <https://review.opendev.org/#/q/topic:bp/provider-config-file> Nova: using provider config file for custom resource providers * <https://review.opendev.org/681955> Nova: clean up some lingering placement stuff * <https://review.opendev.org/664867> OSA: Add nova placement to placement migration * <https://review.opendev.org/681343> Charms: Disable nova placement API in Train * <https://review.opendev.org/#/q/topic:bug/1841481> Nova: stop using @safe_connect in report client # End 🐈 -- Chris Dent ٩◔̯◔۶ https://anticdent.org/ freenode: cdent

[neutron] [neutron-lib] Change of in neutron-lib lead
by Miguel Lavalle 16 Sep '19

16 Sep '19

Dear Neutrinos, Many of you might have heard the Russel Boden's employer is changing his focus. As a consequence, Boden won't be able to continue leading our neutron-lib efforts. We want to thank you for the great job he has done over many cycles in advancing this sub-project. We are also looking for a volunteer to lead neutron-lib. Boden put together an etherpad with what needs to be done in the near future: https://etherpad.openstack.org/p/neutron-lib-volunteers-and-punch-list Regards Miguel

[cloudkitty] 13/09 meeting summary
by Luka Peschke 16 Sep '19

16 Sep '19

Hi everyone, This is the recap of the cloudkitty team IRC meeting that happened on 13/09. The logs can be found at [1]. All features patches we wanted to integrate have been merged for the feature freeze dealine. An experimental v2 storage driver for Elasticsearch has also been merged. Concerning the community goals: python3-first has been implemented early, however we're late for PDF docs generation, as we've got several issues when trying to generate PDF documentation, especially with tabs. A patch for cloudkitty has been proposed today [2]. Patches for the client and specs repos are to be done. They're our current top priority. From now on, the IRC meeting will be held twice every month, on the first and third monday at 14h UTC. This means that the next meeting will happen on october 7th. We plan to send a recap to this mailing list for each meeting. For the U cycle, we'd like to use storyboard a lot more. For now, it's been used for features and major bugs only, but we'll use it for every non-trivial patch from now on. Our temporary roadmap for U is the following: * Design and implement a new rating module. * Support time-based grouping in the /v2/summary endpoint. This would allow to easily create charts with cloudkitty's API. * [To be discussed] Stop differenciating "groupby" and "metadata" attributes, as these seem to be confusing for admins. * Port as many v1 API endpoints as possible to v2. Best regards, Luka Peschke (peschk_l) [1] http://eavesdrop.openstack.org/meetings/cloudkitty/2019/cloudkitty.2019-09-… [2] https://review.opendev.org/#/c/682364/

[requirements] [ironic] Bumping test-requirements on stable/train for the PDF goal?
by Dmitry Tantsur 16 Sep '19

16 Sep '19

Hi all, we (ironic) have a few deliverables that got the PDF goal fulfilled after stable/train was branched. Is it reasonable to still pursue the goal on stable/train even if it requires raising the openstackdoctheme requirement? An example is https://review.opendev.org/#/c/682274/ Thanks, Dmitry

[openstack-dev] [neutron]IPv6 Prefix Delegation could not activated in newest version Neutron
by Shuai Zhao 16 Sep '19

16 Sep '19

Hi All, I'm working on validate the IPv6 PD in newest Neutron. What I want is to offer the Global Unified address to the VM and I find PD is the good solutions for me. I follow the guide *https://docs.openstack.org/neutron/latest/admin/config-ipv6.html <https://docs.openstack.org/neutron/latest/admin/config-ipv6.html> *to setup PD and dibbler-server and devstack, but I find I could not to trigger the PD process. The Dibbler server print nothing when attach the Subnet to router has external gateway. All procedure has recorded to the bug: https://bugs.launchpad.net/neutron/+bug/1844123. Thanks for your action and help in advance!
