[all][tc][ptls] Eventlet: Python 3.13 - Attach your seatbelt
by Herve Beraud 06 Sep '24

06 Sep '24

Hi all, As Python 3.13 is close to become a reality, new concerning incompatibilities between this new CPython version and Eventlet also become a reality: - https://github.com/eventlet/eventlet/issues/964 Fedora Python maintainers proposed a patch, but for now the problem remains unsolved. Also, many people reported bugs related to incompatibility between python3.12/dnspython/eventlet/pip-system-cert. There is an example who summarize well the problem https://github.com/eventlet/eventlet/issues/957 Do you have some visibility concerning the adoption of Python 3.13 into Openstack? Turbulences ahead... -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/

by Edward Hope-Morley 05 Sep '24

05 Sep '24

Hi everyone, I would like to propose Brian Haley and Nicolas Bock for the OpenStack Charms core development team. Both Brian and Nicolas have been members of the stable charms core team since 2023 and been hugely helpful in that role, providing insightful feedback to reviews as well as contributions of their own. Nicolas has also been a contributor to the OpenStack charms for many years and Brian is well versed in the ways of upstream OpenStack maintenance through his role as Neutron PTL so I have full confidence that they will prove valuable additions to the charms-core team. Thank you both for your contributions to the project! Regards, Ed

[Kolla] [LetsEncrypt] Internal/External/Backend Certificates
by jjjamesg＠proton.me 05 Sep '24

05 Sep '24

Hi all, another one here that can't seem to get kolla running with letsencrypt certs, just curious as to what settings are required for kolla to pull internal/external/backend certs from letsencrypt? I've looked at the docs and have tried a few settings but keep getting errors, sure i had this working last week before i tore it down ready to deploy for production and now i just cant get it to complete the deployment because of certs, only thing i can think of is i need to run kolla-ansible -i multinode certificates but i thought that was just for self made certs? Also, what are best practices for backend tls certs, self signed or using the internal cert etc?? Is it possible to use letsencrypt at all for backend? Cheers all

[all][dev][ops][tc] Bridging the gap between community and contributing orgs
by Jeremy Stanley 05 Sep '24

05 Sep '24

The tl;dr on this is that I'm opening a broad community discussion on how we can, collectively through improved communication, better bring together our established contributors with casual and prospective contributors who struggle to find successful patterns of contribution, so that we might all support each other in order to benefit OpenStack as a whole. Read on for details... OpenStack's TC has requested that foundation staff, when in conversation with representatives of member organizations, encourage participation in the project and collect feedback on any related challenges those organizations encounter in their attempts to do so. In order to better understand the feedback and brainstorm achievable recommendations for the broader community[*], Community Managers on the foundation staff started to work with a small focus group of established contributors with a solid understanding of what successful patterns of contribution look like. It also came to light that established contributors experience many of the same sorts of challenges, even more so if they don't have the luxury of focusing full-time upstream, and so success often comes down to knowing how to effectively navigate those challenges. The community's goal with this exercise is to improve everyone's experience, and your help is needed to do that! The most common themes reported by those struggling to contribute are not related to tooling or workflow confusion, but instead seem to come down to basic communication challenges. Ideas so far to address these gaps include: * Review bandwidth - Ensure contributors and companies understand the importance and benefits of code review - Incentivize and credit meaningful "+1" reviews more - Understand that the volume of changes and limited reviewer bandwidth often means proposals aren't reviewed quickly (or at all), and their proponents may need some additional tenacity and engagement with the team to get their work noticed - Utilize "review dashboards" as a way to find stale changes which have fallen through the cracks * Review strategy and etiquette - Be clear about the meaning of votes on changes, especially negative ones, and set explicit timelines for things like "procedural -2" or WIP blocks when their approval needs to be delayed - Focus on comments and requests that affect whether or not the change can be merged after the fixes are submitted, rather than requesting trivial adjustments to an unsuitable change which has more fundamental problems - Reciprocate with reviews of changes from new reviewers you see leaving insubstantial reviews, demonstrating to them what deeper and more meaningful reviewing looks like * Mentoring newcomers - Established contributors with sufficient bandwidth can help mentoring newcomers, potential core reviewers and new leaders - Mentoring can happen as part of internship programs as well as by helping newcomers determined to become active contributors; both ways should be embraced and utilized What challenges are you facing? And, how would you improve them? Two weeks from now, we'll have a forum session at the OpenInfra Summit Asia in Suwon[**] where our community can refine these possible approaches and integrate others, as well as bring attention to them and promote their application. I've also proposed a similar forum session for OpenInfra Days North America in Indianapolis a month after that, where we can hopefully continue this conversation. The goal for this multi-stage effort is to improve the contribution experience for established participants, casual contributors and newcomers alike. While it's easy to jump to blaming in these situations, it will be far more productive if we can focus on the challenges and experiences that we would each like to remove or improve for ourselves and others in our community. As we find ways together to improve our efficiency, we can reduce the load on all contributors and lower the barriers for people to join and participate.

[cinder] Offering local storage using the device mapper clone target
by Jan Horstmann 04 Sep '24

04 Sep '24

Hello cinder team and other interested parties, I have recently started thinking about ways to offer local storage as part of the OpenStack block storage service. Naturally any solution would require to transparently migrate volumes to and with the instances they are attached to, so that the user experience of being able to access their storage from anywhere would not be degraded. Fortunately, with the device mapper clone target ([1]), a mechanism is available in the linux kernel which allows to do exactly that: Create copies of devices (even network attached ones) while allowing to immediately use the target device. I have detailed the motivation and some implications of having local storage in the block storage service in a blog post [2], which I do not want to repeat here in order to not make this mail longer than it needs to be. The blog post also outlines a way to implement a cinder driver leveraging this mechanism, which is loosely based on the way cinder migrates volumes between backends, i.e.: When a volume is going to be attached, a new volume is created on the instance's host, which is backed by a device mapper clone target with the original volume as its source; Then the volume objects are switched and a local connector is returned, which may be used immediately. Since then I went ahead and created a proof of concept cinder driver ([3]), which roughly follows what is outlined in the post (some lessons were already learned during implementation). The driver is based on the in-tree lvm driver for basic volume management and can do basic things like create/delete, attach/detach and also handles live migration and rebuilding of instances. There is nothing currently regarding snapshots and volume migrations will definitly not work as expected yet, but it should be sufficient to get a feeling for the general idea. I am currently looking for feedback on the idea and the implementation and would like to know if this is of interest to others. I am happpy to answer any questions or present this in more detail. In case anyone wants to take the driver for a spin I am going to leave some instructions on how to set up the environment in [4]. Regards, Jan [1] https://docs.kernel.org/admin-guide/device-mapper/dm-clone.html [2] https://scs.community/2024/07/12/local-block-storage-via-dm-clone/ [3] https://github.com/janhorstmann/openstack-cinder/tree/59e1808a24d112d2e8d08… [4] - Set up an OpenStack environment - Create an lvm2 volume group and run a cinder volume service on every hypervisor - Configure a new backend on every volume service with the same `volume_backend_name` Configure it like you would an lvm backend, but with `volume_driver = cinder.volume.drivers.dmclone.DMCloneVolumeDriver`, e.g.: [local-volumes] volume_driver = cinder.volume.drivers.dmclone.DMCloneVolumeDriver volume_group = local volume_backend_name = local-volumes target_helper = tgtadm target_protocol = iscsi lvm_type = default I have tested with the values above, but any target driver should work -- Jan Horstmann Senior Cloud Engineer Mail: horstmann(a)osism.tech Web: https://osism.tech OSISM GmbH Talweg 8 / 75417 Mühlacker / Deutschland Geschäftsführer: Christian Berendt Unternehmenssitz: Mühlacker Amtsgericht Mannheim, HRB 750852

[all][rbac][tacker][horizon][neutron][octavia] oslo.policy 4.4.0 enable the RBAC new defaults by default
by Ghanshyam Mann 03 Sep '24

03 Sep '24

Hi All, You might have seen some fixes and testing changes on your project to test the oslo.policy 4.4.0. oslo.policy 4.4.0 enables the RBAC new defaults by default, which means those will be enabled for all the OpenStack services unless they have disabled them by overriding the default value. It enables both enforce_scope as well enforce_new_defaults. The requirement change[1] adds the oslo.policy 4.4.0 in upper-constraints which will enable the latest oslo.policy in upstream CI. Along with jobs failing on requirement change, I tested more integration jobs and fixing the failures[2]. Most of the fixes have been merged, and a few of them are up for review. Below is the list of fixes up for review, please merge them before the requirement change is merged. If there is something else I missed to test and failed, let me know on IRC or here. In-progress fixes: - Horizon: - https://review.opendev.org/c/openstack/horizon/+/927571 - Tacker: - https://review.opendev.org/c/openstack/tacker/+/926089/5 - Neutron + Designates job (making it non-voting until we figure out the root cause): - https://review.opendev.org/c/openstack/neutron-tempest-plugin/+/927648 - Octavia (Michael is working on more modifications on this ): - https://review.opendev.org/c/openstack/octavia-tempest-plugin/+/926867 [1] https://review.opendev.org/c/openstack/requirements/+/925464 [2] https://review.opendev.org/q/topic:%22secure-rbac%22+owner:gmann@ghanshyamm… -gmann

Re: Migratekit: near-live migrations from VMware to OpenStack
by Oliver Weinmann 02 Sep '24

02 Sep '24

Hi Mohammed, We struggled using virt-v2v directly with OpenStack. Our approach was using ovftool to export the VM as OVA and then create a qcow2 image that we can import in OpenStack. So many manual steps involved. So I tested your tool aganst vsphere 7.x vcenter. But I just can't manage to get it working. It keeps complaining about the path of the source VM. I can use the following just fine with virt-v2v: virt-v2v -v -x --password-file pass.txt -ic vpx:// user123(a)vcenter.somedomain.local /GE%Office%20One/Projects/esx01.somedomain.local?no_verify=1 test-vm-01 Using the same in your tool: docker run -it --rm --privileged \ -v /dev:/dev \ -v /usr/lib64/vmware-vix-disklib/:/usr/lib64/vmware-vix-disklib:ro \ --env-file <(env | grep OS_) registry.atmosphere.dev/library/migratekit:latest migrate \ --vmware-endpoint vcenter.somedomain.local \ --vmware-username user123 \ --vmware-password XXXXXX \ --vmware-path /GE%Office%20One/Projects/esx01.somedomain.local/test-vm-01 Results in: Error: vm '/GE%Office%20One/Projects/ esx01.somedomain.local/test-vm-01 ' not found I tried many different variants of the path none has worked. Is there a way to lookup the path of a VM? I can also use: virsh -c 'vpx:// user123(a)vcenter.somedomain.local /GE%Office%20One/Projects/esx01.somedomain.local?no_verify=1 list --all which shows me all VMs running on that particular ESXi host.

Hi Team , We have an 'Openstack on Ansible' Private cloud environment with 3 controllers & 35 Compute host nodes. Age of this environment is around 4 yrs. DISTRIB_RELEASE: 21.2.1 DISTRIB_CODENAME: Ussuri DISTRIB_DESCRIPTION: Openstack-Ansible Top of this Linux containers are there where the services are running inside such as neutron, galera, horizon, keystone, etcd, nova-api, utility etc for all 3 controllers. Current Set Up: We find in haproxy config file only controller2 & controller3 are configured. So the galera container along with Mariadb Services are running fine within controller2(Primary) & controller3. But Galera container in controller1 is stopped & mariadb service not running here. Issue Started with: All of suddent we faced, user not able to log in dashboard 5 days back. The dashboard page is not getting loaded. Action Taken: We find Maria-DB in controller2 is non-primary & DB on controller-3 is down. Made Maria-DB in controller2 primary & DB on controller-3 up which resulted to load the page & log in. Current Issue: 1) But the Dashboard page is too slow to work. Sometime throwing 504-Timed out error 2) VM Console(VNC) not working for any VM 3) NOt able to create any VM(Showing 'Scheduling' continuously) 4) 25/35 Hypervisons are showing down in Dashboard within 'Hypervisor list' tab but those are up as per CLI 5) Not able to create any volume Request you to go through the Problem description & Can anybody help me out providing the solution for the same? Pl do intimate me if any more info is required. Regards, Sudeb Ghosh sudeb_ece(a)yahoo.co.in BR// Sudeb Ghosh 7044064878 9332034788
