[nova][dev] Improved scheduling error messages
by Brito, Hugo Nicodemos 30 Aug '21

30 Aug '21

Hi, In a prototype, we have improved Nova's scheduling error messages. This helps both developers and end users better understand the scheduler problems that occur on creation of an instance. When a scheduler error happens during instance creation via the nova upstream, we get the following message on the Overview tab (Horizon dashboard): "No valid host was found." This doesn't give us enough information about what really happened, so our solution was to add more details on the instance's overview page, e.g.: **Fault:Message** attribute provides a summary of why each host can not satisfy the instance’s resource requirements, e.g. for controller-0, it indicates “No valid host was found. Not enough host cell CPUs to fit instance cell” (where cell is a numa-node or socket). **Fault:Details** attribute provides even more detail for each individual host, for example it shows that the instance “required” 2 CPU cores and shows the “actual” CPU cores available on each “numa” node: “actual:0, numa:1” and “actual:1, numa:0”. These details are also present using the OpenStack CLI, in the _fault_ attribute: - openstack server show <instance> With that in mind, we'd like to know if you are open to consider such a change. We are willing to submit a spec and upstream that implementation. Regards, - nicodemos

RabbitMQ performance improvement for single-control node
by Eugen Block 30 Aug '21

30 Aug '21

Hi *, I would greatly appreciate if anyone could help identifying some tweaks, if possible at all. This is a single control node environment with 19 compute nodes which are heavily used. It's still running on Pike and we won't be able to update until complete redeployment. I was able to improve the performance a lot by increasing the number of workers etc., but to me it seems the next bottleneck is rabbitmq. The rabbit process shows heavy CPU usage, almost constantly around 150% according to 'top' and I see heartbeat errors in the logs (e.g. cinder). Since there are so many config options I haven't touched them yet. Reading some of the tuning docs often refer to HA environments which is not the case here. I can paste some of the config snippets, maybe that already helps identifying anything: # nova.conf [oslo_messaging_rabbit] pool_max_size = 1600 pool_max_overflow = 1600 pool_timeout = 120 rpc_response_timeout = 120 rpc_conn_pool_size = 600

[kolla][operators] Critical regression in Wallaby
by Radosław Piliszek 28 Aug '21

28 Aug '21

Dear Operators of Kolla-based deployments, There is a critical regression in current Kolla Ansible Wallaby code that results in an environment that shuts down VMs on each libvirtd container stop or restart on non-cgroupsv2 distros (so CentOS, Ubuntu and Debian Buster but not Debian Bullseye). [1] The fix is already available. [2] Please apply it to your Kolla Ansible installation if you are using Wallaby. Do note the fix only applies after redeploying which means redeployment action will still trigger the buggy behaviour that once! What to do if you have already deployed Wallaby? First of all, make sure you don't accidentally take an action that stops nova_libvirt (including restarts: both manual and those applied by Kolla Ansible due to user-requested changes). Please apply the patch above but don't rush with redeploying! Redeploy each compute node separately (or in batches if you prefer) - using --limit commandline parameter - and always make sure you have first migrated relevant VMs out of the nodes that are going to get nova_libvirt restarted. This way you can safely fix an existing deployment. We will be working on improving the testing to avoid such issues in the future. Acknowledgements Thanks to Ignazio Cassano for noticing and reporting the issue. I have triaged and analysed it, proposing a fix afterwards.

Hi Everyone, Is there any feature to prevent multiple login sessions for the same user in Horizon? That feature could be used to block a second login attempt for the same user when another session already exists or invalidate the the first session right after a second session is opened by the user. Any reference documentation would be very helpful. Kind regards, rsoaress

[release] Release countdown for week R-5, Aug 30 - Sep 03
by Herve Beraud 27 Aug '21

27 Aug '21

Development Focus ----------------- We are getting close to the end of the Xena cycle! Next week on 02 September, 2021 is the Xena-3 milestone, also known as feature freeze. It's time to wrap up feature work in the services and their client libraries, and defer features that won't make it to the Yoga cycle. General Information ------------------- This coming week is the deadline for client libraries: their last feature release needs to happen before "Client library freeze" on 02 September, 2021. Only bugfix releases will be allowed beyond this point. When requesting those library releases, you can also include the stable/xena branching request with the review. As an example, see the "branches" section here: https://opendev.org/openstack/releases/src/branch/master/deliverables/pike/… 02 September, 2021 is also the deadline for feature work in all OpenStack deliverables following the cycle-with-rc model. To help those projects produce a first release candidate in time, only bugfixes should be allowed in the master branch beyond this point. Any feature work past that deadline has to be raised as a Feature Freeze Exception (FFE) and approved by the team PTL. Finally, feature freeze is also the deadline for submitting a first version of your cycle-highlights. Cycle highlights are the raw data that helps shape what is communicated in press releases and other release activity at the end of the cycle, avoiding direct contacts from marketing folks. See https://docs.openstack.org/project-team-guide/release-management.html#cycle… for more details. Upcoming Deadlines & Dates -------------------------- Xena-3 milestone (feature freeze): 02 September, 2021 (R-5 week) RC1 deadline: The week of 13 September, 2021 (R-3 week) Final RC deadline: The week of 27 September, 2021 (R-1 week) Final Xena release: 06 October, 2021 -- Hervé Beraud Senior Software Engineer at Red Hat irc: hberaud https://github.com/4383/ https://twitter.com/4383hberaud

[manila] Propose haixin to manila-core
by Goutham Pacha Ravi 26 Aug '21

26 Aug '21

Hello Zorillas, Haixin (haixin77 on Launchpad, haixin on OFTC) has been contributing to manila since the Train release. He is part of a team that operates manila at scale at Inspur and supports their storage integrations within OpenStack. He diligently files bug reports, interacts with the community and has thus far contributed several important perf-scale improvements across the service stack. He also provides useful review feedback to fellow contributors, and participates in team-efforts such as bug squashes, review jams and mentorship of new contributors. I'm delighted to note that he wants to take on some more maintenance responsibility [2]. So, with your support I'd like to add haixin to the manila-core group on gerrit. This "power" comes with significant responsibility and I'm hoping haixin will ramp up soon and help share some of the load from the existing maintainers. Please let me know your thoughts, +/- 1s, 2s, 2-cents, etc! Thanks, Goutham [1] https://www.stackalytics.io/?user_id=haixin77&project_type=all&release=all&… [2] https://docs.openstack.org/manila/latest/contributor/manila-review-policy.h…

[devstack][neutron][manila] Instances having trouble getting to external network with OVN
by Goutham Pacha Ravi 26 Aug '21

26 Aug '21

Hi, Some third party storage CI running against manila repos has had issues setting up VMs and providing access to external resources in devstack; these issues started around the time that the default ml2 plugin was switched to OVN. Folks in the manila team aren't familiar with devstack/CI networking to determine how to resolve these; and we'd totally appreciate help from networking experts in this regard. A sample local.conf file used by the CI is here: http://paste.openstack.org/show/807449/ Manila's tests: - create a private tenant network - setup a router that connects the private network to the public network - create a nova VM on the private tenant network - attempt to mount a share via NFS from within this VM The final step fails because the NFS mount command times out within the test VM: tempest.lib.exceptions.SSHExecCommandFailed: Command 'sudo mount -vt nfs "10.16.xx.xx:/share-96ae8d0c-8bab-4fcd-b278-51a6f473e03c-manila" /mnt', exit status: 32, stderr: mount.nfs: mount(2): Connection timed out mount.nfs: Connection timed out stdout: mount.nfs: timeout set for Mon Jun 28 14:47:19 2021 mount.nfs: trying text-based options 'vers=4.2,addr=10.16.xx.xx,clientaddr=10.1.0.26' The timeout seems to be because the VM is unable to reach the NFS server that's external to the devstack host. The NFS server is reachable from the devstack host. Have there been any changes to devstack configuration that we need to be aware of, wrt VMs having access to the external network? Thanks, Goutham

[election][cloudkitty] PTL Candidacy for Yoga
by Rafael Weingärtner 26 Aug '21

26 Aug '21

Hello Cloudkitters, I would like to nominate myself to serve as Cloudkitty PTL for the Yoga cycle. I've been working with OpenStack since 2018 and contributing to Cloudkitty since May 2019. I hope that we can continue to achieve goals together, making CloudKitty better and more robust. We should also aim to grow our contributor base and continue to spread the word about CloudKitty (blog posts, social media, etc). Features that I think we should aim for during the next cycle: the reprocessing API (https://review.opendev.org/c/openstack/cloudkitty/+/799207) and Storage state status ( https://review.opendev.org/c/openstack/cloudkitty/+/777442) both of which are already proposed and in the review process. Best regards, -- Rafael Weingärtner

[kolla] PTL non-candidacy
by Mark Goddard 26 Aug '21

26 Aug '21

Hi Koalas, As I suspect may be the case with many PTLs, I first took on the role largely because it needed to be done and no other candidates were forthcoming. As I settled into the role I found that I actually rather enjoyed it. The project has certainly come far since I first started using it in 2016, and I'm proud to have helped to steer the ship for a while. After 5 release cycles, the time has come to pass on the Kolla PTL hat to another Koala. I will still be actively involved in the community, and will be happy to help the next PTL while they get comfortable. Thank you to everyone who has supported me in this role, and to everyone who makes Kolla such a great community to be involved in. Long live Kolla! Cheers, Mark

[election][kolla] PTL candidacy for Yoga
by Michał Nasiadka 26 Aug '21

26 Aug '21

Hello Koalas, I’d like to nominate myself to serve as the Kolla PTL for Yoga cycle. I’ve been a Kolla/Kolla-Ansible user and developer since 2015/2016. Initially I started out as a user while working at IBM, and started my first small contributions in Ocata. I became a core while working in Nokia (Feb/Mar 2019) - and continued working on Kolla (and Kayobe) when I moved to StackHPC 2 years ago. I was lucky enough to change companies - but my upstream OpenStack interest remained the same. First and foremost - I’d like to thank Mark for the work he did on previous cycles, especially by bringing users together in the Kolla club, improving Kolla-Ansible’s performance and introducing Kayobe to the Kolla family. As a PTL I’d like to continue focus on: • User experience - documentation, work on eliminating user pain points, Kolla Klub-like activities • CI stability and improvements • Helping new contributors Thanks, Michal

What OS image can I use for Docker Swarm in Magnum?
by Paolo Celati 26 Aug '21

26 Aug '21

Hi, I'm looking to set up Docker Swarm using Openstack Magnum and I noticed the user guide for magnum lists only Fedora Atomic as supported. If I'm not mistaken though Atomic has been discontinued for a while now, so I'm wondering what you use for this use case. Can I use Fedora CoreOS instead, and if so are there any gotchas I should know as a first time Magnum user? Thanks in advance, Paolo

[cinder] high-priority reviews this week
by Brian Rosmaita 26 Aug '21

26 Aug '21

Hello Cinder team, As I mentioned at today's meeting, the cinderclient must be released next week, and this means that any Xena cinder features that we want supported in the Xena cinderclient need to merge into cinder first. We've got two cinder patches that introduce new microversions, and thus impact cinderclient. So please put the following patches at the top of your reviewing list: (1) "Snapshot in-use volumes without force flag" cinder: https://review.opendev.org/c/openstack/cinder/+/789564 cinderclient: (simply requires bump in MAX_VERSION, will be done in the release note patch) (2) "Expose volume & snapshot use_quota field" cinder: https://review.opendev.org/c/openstack/cinder/+/786386 cinderclient: https://review.opendev.org/c/openstack/python-cinderclient/+/787407 (very small patch) A slight complication is that 786386 is stacked on top of some other patches. On the other hand, these are all nicely done and present learning opportunities: - https://review.opendev.org/c/openstack/cinder/+/791240/ -- this is a good one to review if you're interested in how the automated tests to verify the request/response samples in the api-ref work - https://review.opendev.org/c/openstack/cinder/+/786383 -- relatively small patch with great unit test coverage - https://review.opendev.org/c/openstack/cinder/+/786384/ -- this is a good one if you want to get better acquainted with Cinder's use of Oslo Versioned Objects - https://review.opendev.org/c/openstack/cinder/+/786385 -- this is worth looking at to see the online data migration strategy Cinder uses to enable rolling upgrades - https://review.opendev.org/c/openstack/cinder/+/786386 -- this is the patch that introduces a new API microversion; it looks big, but a lot of the files are sample requests/responses for the api-ref Happy reviewing!

[election][TripleO] James Slagle candidacy for TripleO PTL for Yoga
by James Slagle 26 Aug '21

26 Aug '21

I'm submitting my candidacy for TripleO PTL. I look forward to the opportunity to help the community as we tackle some of our upcoming challenges — the transition to CentOS/RHEL 9, increasing complexity around container management, and revisiting our commitments to our adopted tooling. I'd suggest that to assist with these efforts, we focus on our review prioritization and in progress work streams. I would like to see folks representing review priorities during the TripleO meeting and on an etherpad. I'd also like to see less parallel streams of work, with the opportunity for more folks to collaborate on common priorities. If elected as PTL, I would plan to organize the efforts around such an approach. Thank you for the consideration. https://review.opendev.org/c/openstack/election/+/805840 -- -- James Slagle --

[kolla][wallaby] nova_libvirt restarting causes vm shutdown
by Ignazio Cassano 26 Aug '21

26 Aug '21

Hello, I tried to update kolla wallaby because new images has been released. During the update nova_libvirt container restarted and all vm went down. So I verified that every time I restart nova_libvirt container, all vm restarted and nova_compute reports lost connection with libvirt. In openstack installations where docker is not used, the libvirt restart does not cause vm shutdown. I opened a bug: https://bugs.launchpad.net/kolla-ansible/+bug/1941706 Ignazio

Hi, I am trying to deploy openstack with tripleO using VMs and nested-KVM for the compute node. This is for test and learning purposes. I am using the Train version and following some tutorials.

[ops] [cinder] Cinder driver for Dell EMC PS Series on Train
by Massimo Sgaravatto 25 Aug '21

25 Aug '21

Dear all In our Cloud we have multiple backends for Cinder. One of them is using the Dell EMC PS Series volume driver My understanding (reading https://docs.openstack.org/releasenotes/cinder/ussuri.html) is that the driver doesn't work anymore in >= Ussuri A while ago we migrated to Train (using CentOS7 as operating system) and everything kept working fine. We are now trying to migrate to CentOS8 (still using Train) and the cinder volume service for the equallogic backend doesn't work anymore In the log file I found something like this [*] We already planned to dismiss that backend (but we planned to do that before next Openstack update). Does anyone know if that driver is supposed to work with Train and CentOS8 (and therefore python3) ?

[Kolla-Ansible][Ironic] Baremetal node Cleaning fails in UEFI mode, but succeeds in Legacy Bios Mode
by Anirudh Gupta 25 Aug '21

25 Aug '21

Hi Team, I am trying to provision Baremetal node using IRONIC with KOLLA-ANSIBLE. I have enabled the support of "IPXE" in kolla-ansible as well. I am getting an issue that when my baremetal node is booted in UEFI Mode, it is not able to find file *"ipxe.efi"* as a result of which cleaning of the node fails [image: image.png] But when I change the BIOS Mode of my Baremetal Node to Legacy.BIOS, it looks for the file "*undionly.kpxe"* for which the acknowledgment is received and Data Packets are transferred. Eventually the cleaning of node is also a success. [image: image.png] Is there any limitation of IRONIC or KOLLA-ANSIBLE side that provisioning of Baremetal Node can only be done in Legacy Bios Mode? For bare metal provisioning in UEFI mode, is there any other parameter that needs to be enabled. Regards Anirudh Gupta

[all][elections][tc] TC Campaigning Kickoff
by Ian Y. Choi 24 Aug '21

24 Aug '21

Developers, The TC Election Campaigning Period has now started [1]. During the next couple days, you are all encouraged to ask the candidates questions about their platforms [2], opinions on OpenStack, community governance, and anything else that will help you to better determine how you will vote. This is the time to raise any issues you wish the future TC to consider, and to evaluate the opinions of the nominees prior to their election. Candidates, Each of you has posted a platform [2], and announced your nomination to the developers. From this point, you are encouraged to ask each other questions about the posted platforms, and begin discussion of any points that you feel are particularly important during the next cycle. While you are not yet TC members, your voices and opinions about the issues raised in your platforms and questions raised by the wider community will help ensure that the future TC has the widest possible input on the matters of community concern, and the electorate has the best information to determine the ideal TC composition to address these and other issues that may arise.

We've improved several features vital to large clusters, such as container sharding, partition power increases, and storage-policy reconciliation. We've improved the durability of erasure-coded data immediately after a write. We've made our logs, metrics, and errors more useful. We focus on operators for several reasons. Operators are at the junction of the software we write, the hardware we use, and the clients we serve. They have perhaps the best perspective to see the value-to-effort ratio of prospective improvements. They run the experiments that establish and optimize deployment patterns. They manage the drives and networking that allow us to serve hundreds of petabytes at terabits per second, and their projections tell us that storage must become bigger and faster. Thinking like an operator, there are several areas where Swift should improve. Replication and reconstruction continue to be a delicate balancing act between moving data for the sake of expansion vs. ensuring durability. We need a better handle on which data gets accessed, how frequently, and with what sort of performance -- ideally indexed by tenant and even user. As more clusters are stood up in more regions, we need to improve monitoring and recovery such that clusters can run with minimal human intervention. I look forward to working with the community to bring Swift into a future of ever-larger and ever-more-numerous clusters. Tim

[election][Release_Management] PTL candidacy for Yoga
by Előd Illés 24 Aug '21

24 Aug '21

Hello OpenStack Community, I would like to announce my candidacy for PTL of the Release Management team for the Yoga cycle. I became core member in the Release Management team during Wallaby cycle to help the work of the team with release patch reviews, but I was involved in the release process for some time already as my focus has been Stable Maintenance (especially around the introduction of the Extended Maintenance process) as being member of the stable-maint-core group. Thanks to the great work of the former PTLs and team members of the Release Management team, now the process is fairly automated and should be straightforward to follow. During the Yoga cycle I'm planning to get familiar with all the aspects of the release management (with the help of the more experienced team members) and continue the work that my predecessors started and keep things maintained. Thanks for your consideration, Előd Illés (elodilles)

[election][cinder] PTL Candidacy for Yoga
by Brian Rosmaita 24 Aug '21

24 Aug '21

Hello everyone, I'd like to announce my candidacy for Cinder PTL for the Yoga cycle. The primary challenge we face in the Cinder community continues to be that our reviewing bandwidth has declined at the same time third-party driver contributions have not decreased. As I see it, the problem is that many vendors who maintain third-party drivers do not appear to be clear on the concept of community participation. (For what it's worth, I think this is more a manager problem than a developer problem, but the effect on Cinder is the same, namely, lots of request for reviews and not much doing of reviews. The Cinder documentation has information about how to review, how you don't need to be a core to do valuable reviews, etc., but it's not clear that many people have actually read them.) The Cinder community has tried to address this participation deficit in Xena by providing more upstream activities for contributors (for example, the monthly Festival of XS reviews [0] and the weekly Bug Squad meetings [1]), and these have had decent participation. In Yoga, I'd like to explore having some kind of Review Squad meeting to give people a chance to get "live" feedback on features under development. Some people do use the weekly Cinder meeting for this, but not everyone takes advantage of that, plus weekly meeting time is limited. I hate to propose yet another team meeting, but on the other hand, the bug squad and festival of reviews meetings are extremely productive, so I don't mind proposing another *productive* meeting. (We'll simply cancel it if it turns out that people don't take advantage. Also, I'm open to other ideas ... the key issue is providing faster feedback and more visibility for people developing cinder features, and allowing cinder cores to use their review time productively. So two key issues.) On the positive side, we did add a new cinder core during Xena and there's another person right on the verge of being proposed as a core. So that will help address review bandwidth, though I want to stress that non-core reviews are extremely important to the project as well. Our core reviewers also develop features and fix bugs--they are not full-time code reviewers. And the way to become a cinder core is to review widely in the project and demonstrate a good breadth of knowledge of the software. (As always, anyone currently working on cinder project who's interested becoming a cinder core, please contact me (or any of the current cores) to discuss what the expectations are.) Also on the good side is that we've done quite a bit of work on the Cinder CI this cycle. (I'm not going to tempt fate by saying anything more about that.) With respect to the details of Cinder development in Yoga, I expect those to emerge from our virtual PTG discussions in October. You can help set the agenda here: https://etherpad.opendev.org/p/yoga-ptg-cinder-planning To summarize, I would like to continue working on improving the review throughput of the Cinder team and find additional ways to get people more thoroughly involved in the project. Thanks for reading this far, and thank you for your consideration.

[election][requirements][ptl] PTL Candidacy for Yoga
by Matthew Thode 24 Aug '21

24 Aug '21

I would like to announce my candidacy for PTL of the Requirements project for the Yoga cycle. The following will be my goals for the cycle, in order of importance: 1. The primary goal is to keep a tight rein on global-requirements and upper-constraints updates. (Keep things working well) 2. Un-cap requirements where possible (stuff like prettytable). 3. Fix some automation of generate contstraints (pkg-resources being added and setuptools being dropped) 4. Audit global-requirements and upper-constraints for redundancies. One of the rules we have for new entrants to global-requirements and/or upper-constraints is that they be non-redundant. Keeping that rule in mind, audit the list of requirements for possible redundancies and if possible, reduce the number of requirements we manage. I look forward to continue working with you in this cycle, as your PTL or not. IRC: prometheanfire -- Matthew Thode

[election][manila][ptl] PTL Candidacy for Yoga
by Goutham Pacha Ravi 24 Aug '21

24 Aug '21

Hello fellow zorillas and other interested stackers, I'm expressing interest to continue serving as PTL for the OpenStack Manila team through the Yoga cycle. I've used my great privilege in this role to affect the community in many small and significant ways over the past four cycles. It has been a smooth ride because of stellar contributors who're beyond motivated and enthusiastic to develop and maintain impactful software while having fun. The enthusiasm is bolstered by grit to be a team with a difference. We jump at the opportunity to help a user or mentor and welcome new contributors or back each other up and help get stuff done, regardless of the "barriers" of affiliation. I enjoy being the occasional enabler to this camaraderie. During the Xena cycle, we mentored two Outreachy interns and on-boarded several new contributors. We added sub team core maintainers in the manila-tempest-plugin project and a new core maintainer across the manila repos. We drove down bug backlogs through bug squash weeks, swarmed to work on the OpenStackClient with a hack-a-thon and crushed the goal to drive down tech debt. We kept the momentum on several multi-cycle efforts such as OpenStackSDK integration, Secure RBAC, Active/Active HA. The Yoga cycle will be critical in our efforts to drive some of these multi-cycle efforts to closure. So, if you will have me, I wish to serve you through the Yoga cycle and get things done. I would tell you it's going to be the best release ever; but I would hold out the distinction for the Zorilla cycle - yes that's what we'll name it, what other cool name will we have anyway :) Thank you for your support, Goutham Pacha Ravi <gouthampravi(a)gmail.com> IRC: gouthamr

[storlets] Transition stable/stein and older branches to EOL
by Takashi Kajinami 24 Aug '21

24 Aug '21

Hi all, I recently noticed that our project still has many old stable branches, from Newton (!!). Because I've never seen any interests to backporting changes to very old branches, I'll propose transitioning stable/stein and older stable branches to EOL. If you have any concerns with that transition please let me know in the following gerrit review. https://review.opendev.org/c/openstack/releases/+/804562 Note that Newton and Ocata will be anywary marked as EOL now since these branches are globally marked as EOL, IIUC. Thank you, Takashi

[ironic] Not running for PTL this cycle
by Julia Kreger 24 Aug '21

24 Aug '21

Greetings everyone, I know I've repeatedly stated over the last few PTGs and midcycle sessions that I wouldn't be running this cycle, but I also realized this morning I had not sent an email. I've served as Ironic's PTL for 7 cycles, and after three and a half years, it is far past time to step down for at least a cycle. Serving the community has been a privilege and an honor, and I'm not planning on going anywhere, but a single person can only take on and handle so much stress. Changes in leadership are also a good thing as it can bring fresh perspective and voices into a project. I encourage Ironic contributors to consider if they would like to serve as the PTL, and to go ahead and submit their candidacy to the elections repository. The only thing I ask is we remain mindful of the needs of the community. I'll be there to help, to guide, and resolve conflicts if necessary. Much as Dmitry, Jim, and Aeva did before me. -Julia

[horizon][dev] Auto-Refresh Feature Proposal
by Santos, Gustavo Faganello 23 Aug '21

23 Aug '21

Hello, everyone. I'm here to find out what you think about the addition of a feature in OpenStack Horizon. As you may know, Horizon requires the user to manually update the page in order to get the most recent data in the system, e.g. if an instance is created, deleted or renamed before the page is reloaded, the user has to hit the refresh button in their browser to see those changes in the page. This applies to the majority of Horizon's pages, including, but not limited to, Instances, Volumes, Users and so on. With that in mind, our team has implemented and tested a prototype of an auto-refresh feature for Horizon. We've been using it for a while now and have received positive feedback from our clients. It automatically updates the information in tables, pie charts (such as the Compute Overview page graphs) and details pages every five seconds, without the need for manually refreshing the page. The information displayed on the page will be replaced by the most recent data without any action from the user or any page reloading. It essentially works by requesting, in the background, the opened page again and again every few seconds through AJAX, and then replacing the old information with the new one if they differ. The feature affects every element in Horizon, except AngularJS ones - the tables in the Compute Images, Key Pairs and Server Groups pages are AngularJS elements and will not be affected by auto-refresh, for example. We are open to looking into this issue in the future, though. Could you please let us know if you would be open to adding such a feature to Horizon? If so, we'd be willing to do the upstream implementation in OpenStack, and we think it would be a great addition to the end users. Kind regards. Gustavo Santos

[election][ironic] PTL Candidacy for Yoga
by Iury Gregory 23 Aug '21

23 Aug '21

Hello Stackers, I would like to nominate myself to serve as Ironic PTL for the Yoga cycle. I've been working with OpenStack since 2015 and contributing to ironic since Oct 2018 (Stein release). I hope that we as a community can continue to achieve goals together, let's not forget that our main objective is to take over the world and make operator's life easier! We should also aim to grow our contributor base and continue to spread the word about Ironic (blog posts, social media, etc). Features that I think we should aim for during the next cycle: Virtual Media visibility, Security Interface using Keylime. Best regards, -- *Att[]'sIury Gregory Melo Ferreira * *MSc in Computer Science at UFCG* *Part of the ironic-core and puppet-manager-core team in OpenStack* *Software Engineer at Red Hat Czech* *Social*: https://www.linkedin.com/in/iurygregory *E-mail: iurygregory(a)gmail.com <iurygregory(a)gmail.com>*
