[neutron] BGP for self-service network
by Deniz AYDIN 29 Mar '23

29 Mar '23

Hi, I am looking for options for removing Layer-2 in the underlay as much as possible. The features explained in the document, BGP floating IPs over L2 segmented network <https://docs.openstack.org/neutron/zed/admin/config-bgp-floating-ip-over-l2…>, solve the problem for floating IPS where layer 2 is only needed between servers and rack switches. Is there any specific reason that this feature is limited to floating IPS? As long as we have unique BGP next-hops defined for every DVR, it can also be used for advertising self-service networks /32 routes. Thanks for the help Deniz

[nova] openstack-tox-pep8 job broken, hold your rechecks
by melanie witt 29 Mar '23

29 Mar '23

Hey all, Sending this to the ML to try to help others who may not have heard about it yet. I didn't know about myself until I saw the job fail on a random nova patch and I looked around to figure out why. It looks like openstack-tox-pep8 is failing 100% in nova due to a newer version of the mypy library being pulled in since a recent upper-constraints bump: https://review.opendev.org/c/openstack/requirements/+/872065 And the job isn't going to pass until the following fix merges: https://review.opendev.org/c/openstack/nova/+/878693 Finally, to help prevent a breakage for this in the future, a cross-nova-pep8 job has been approved: https://review.opendev.org/c/openstack/requirements/+/878748 and will be on its way to the gate once the aforementioned fix merges. I'll post a reply to this email when it's OK to do rechecks again. Cheers, -melwitt

Hey, Due to the recent merge of https://review.opendev.org/c/openstack/requirements/+/872065/10/upper-const… we now use mypy==1.1.1 which includes a breaking behavioural change against our code : https://07de6a0c9e6ec0c6835f-ccccbfab26b1456f69293167016566bc.ssl.cf2.rackc… Thanks to Eric (kudos to him, he was quickier than me), we have a fix https://review.opendev.org/c/openstack/nova/+/878693 Please accordingly hold your rechecks until that fix is merged. -Sylvain

[PTL][release][stable][EM] Extended Maintenance - Xena
by Elõd Illés 29 Mar '23

29 Mar '23

Hi teams, As 2023.1 Antelope was released last week and we are in a less busy period, now is the good time to call your attention to the following: In less than a month Xena is planned to transition to Extended Maintenance phase [1] (planned date: 2023-04-20). I have generated the list of the current *open* and *unreleased* changes in stable/xena for every repositories [2] (where there are such patches). These lists could help the teams who are planning to do a *final* release on Xena before moving stable/xena branches to Extended Maintenance. Feel free to edit and extend these lists to track your team's progress! Note that the *latest* Xena *release* tagging patches ('xena-em' tag) have been generated too in advance [3], please mark with a -1 if your team plans to do a final release, or +1 if the team is ready for the transition. The schedule from now on is as follows: * patches with +1 from PTL / release liaison will be merged, thus those repositories will transition to Extended Maintenance * at the planned deadline (April 20th) the Release Team will merge all of the transition patches (even the ones without any response!) * after the transition, stable/xena will be still open for bug fixes, but there won't be official releases anymore. *NOTE*: teams, please focus on wrapping up your libraries first if there is any concern about the changes, in order to avoid broken (final!!) releases!

[nova][ptg] Today's agenda
by Sylvain Bauza 29 Mar '23

29 Mar '23

(just shamelessly stealing the idea from Neutron's team) Hey foks, Yesterday was a packed day but we didn't really progressed on a lot of topics. Today I'm gonna propose a list of topics in order to improve our sessions's visibility and in order to provide some timeboxing. 13:00 UTC - 14:45 UTC : * How to make sure people can help to review ? * Should we ask for some implementation before accepting a spec ? * CI stability is a nightmare, let's fight over this * Bobcat is a non-SLURP release * Let's clean up our upgrade documentation * Nova community outreach * Clean-up our bug list by abandoning very old LP bug reports ? * Summit/PTG : what could we be doing for the physical PTG ? (Will be 4 weeks before milestone-2) 15:00 UTC - 15:45 UTC : * Nova/Manila cross-project session : Prevent share deletion while it's attached to an instance 16:00 UTC - 17:00 UTC : * When your instance is stuck due to hard affinity policies, what could we do ? * Users reported exhaustion of primary keys ('id') in some large tables like system_metadata. How could we achieve a data migration from sa.Integer to sa.BigInteger ? Details can be found in https://etherpad.opendev.org/p/nova-bobcat-ptg#L192 I assume the packed agenda, particularly the first two hours. As a reminder, people are welcome to add their IRC nicks in each of the courtesy ping list of the related topic. Hope this gives you a taste of joining the Nova PTG today. -Sylvain

[Horizon][policies][keystone] allow _member_ role to add user
by James Leong 28 Mar '23

28 Mar '23

Hi all, I am using kolla-ansible for OpenStack deployment in the yoga version. Would it be possible to allow a user with a "_member_" role to add a user to the respective project? In OpenStack, an admin role allows users to add, delete, and edit a user profile. I would like to have the same privilege added to the "_member_" role. I have tried to modify the file "user.py" in the keystone container at "keystone/common/policies" and restarted the container. However, the button on my horizon dashboard did not appear. How could I integrate the code in order to allow the create button to appear on my dashboard with the "_member_" role? Is there a way to do that? THanks for your help James
