RE: Create image error

Violating limits imposed by the operator should lead to a useful error message rather than an HTTP 5xx error. In any case, there should have been a message in the Glance API log. Perhaps you are using a prerelease version of OpenStack? When you get Devstack from the Git, you may want to specify the version; otherwise, you obtain software that is currently under development. For example, the following gets you the first version released this year (Epoxy): git clone https://opendev.org/openstack/devstack -b stable/2025.1 ------------------------------------------------------------------------------------------------------------------- From: BEDDA Fadhel <fadhel.bedda(a)gmail.com> Sent: Saturday, May 31, 2025 6:00 PM To: berndbausch(a)gmail.com Subject: Re: Create image error Hello, I was able to work around the problem by disabling the limits in the file: /etc/glance/glance-api.conf False instead of True Thanks Le sam. 31 mai 2025 à 09:55, <mailto:berndbausch@gmail.com> a écrit : My guess is that the image service is down.

[kolla-ansible][proxysql] "Wait for backup proxysql container to start" fails
by Bursztynowski Dariusz 20 Jul '25

20 Jul '25

Hello OpenStack community, Installing Kolla-ansible OpenStack 2025.1, I've met a problem with proxysql which does not start (in task [loadbalancer : Wait for backup proxysql to start]) because of unsupported system page size: sudo cat /var/log/kolla/proxysql/proxysql.log <jemalloc>: Unsupported system page size <jemalloc>: Error in malloc(): out of memory I'm working with aarch64 CPU (Raspberry Pi 5 cluster, instructive tool for educational purposes). I have posted the bug here including more detailed description: https://bugs.launchpad.net/kolla-ansible/+bug/2117309 . What is interesting, version 2023.1 works just fine on the same HW/OS platform. I would be grateful for any suggestions on how to resolve this. Best, Dariusz Bursztynowski

[Nova] Unable to fetch CPU/RAM allocation ratios via /os-hypervisors API (Nova API v2.91 vs v2.1 support)
by Thamanna Farhath 19 Jul '25

19 Jul '25

Hello OpenStack community, I'm working with OpenStack (2023.1 kolla ansible) Nova and using the /os-hypervisors API to gather hypervisor information. I noticed that the CPU and RAM allocation ratios (which are shown in the Horizon dashboard) are not included in the response from: GET /os-hypervisors GET /os-hypervisors/{id} We're currently using Nova API version 2.91, but I see that the /os-hypervisors API appears to support only up to version 2.1, I’d like to clarify the following points: Is it expected behavior that the /os-hypervisors API does not return CPU and RAM allocation ratios? Is there any API endpoint that exposes these ratios programmatically? As we are using Nova API version 2.91, but /os-hypervisors seems limited to v2.1, is this a known limitation or design choice? If the only source of truth is the nova.conf configuration file (e.g., cpu_allocation_ratio, ram_allocation_ratio), is there any plan to expose this via API in future releases? It would be helpful to know if this is something we should work around by manually collecting config values, or if there's a more appropriate method in modern Nova setups.

[mariadb][keystone][blazar] Deadlock error on Galera cluster
by Winicius Allan 18 Jul '25

18 Jul '25

Hi community o/ Suddenly, I noticed that the login on the dashboard wasn't working, so I checked the keystone logs. I saw some entries like that: 2025-07-10 00:53:45.120 23 ERROR sqlalchemy.pool.impl.QueuePool oslo_db.exception.DBDeadlock: (pymysql.err.OperationalError) (1205, 'Lock wait timeout exceeded; try restarting transaction') Nova-conductor was also showing messages like these. At the same time, blazer-manager was logging after every _process_event calling: ERROR sqlalchemy.exc.TimeoutError: QueuePool limit of size 1 overflow 50 reached, connection timed out, timeout 30.00 I do not know if it's related to the _process_event method that batches events concurrently[1], and the DB was locked. Well... I increased the max_pool_size from 1 to 2 on blazar-manager, and that message stops showing. Does anyone know what can cause this deadlock generally? I'd like to ask another question: I have three controllers in my environment. Why do controllers with no active VIP address bind connections on the MySQL port, for example: tcp ESTAB 0 0 10.0.0.105:3306 10.0.0.107:50642 users:(("mariadbd",pid=977010,fd=1089)) [1] https://github.com/openstack/blazar/blob/stable/2024.1/blazar/manager/servi… Best regards.

[ops] Very basic newby questions
by Leroy Tennison 17 Jul '25

17 Jul '25

I am looking for a solution to automatically move (upon request) running VMs from one hypervisor to another. The current hypervisors are KVM/QEMU. Just looking at the documentation I am becoming overwhelmed. Questions (A URL which directly addresses the question is quite acceptable): Does OpenStack work with existing hypervisors or would existing hypervisors have to be "converted" (somehow) to OpenStack? If it can be used with existing hypervisors, is there a how-to for this specific task (I understand that OpenStack can do many things). If OpenStack can't be used with existing hypervisors, are you aware of solutions for this need? I have looked at ProxMox but it appears to want centralized storage and very fast networks which doesn't match the environment. Thank you for your help.

[ops][api][all] What are we going to do about pastedeploy usage?
by Stephen Finucane 17 Jul '25

17 Jul '25

oslo.service is going through a lot of churn right now as part of the eventlet migration. We recently noticed that some unrelated WSGI routing code had been inadvertently deprecated, and moved to undeprecate this [1]. In the long-term, however, this code doesn't really belong in oslo.service and should be moved elsewhere. I took a stab at bootstrapping an oslo.wsgi package, and after some hacking I arrived at a dependencies list containing the following: * Paste [2] * PasteDeploy [3] * Routes [4] * WebOb [5] As some of you might know, all of these packages are minimally maintained bordering on unmaintained. I'm not entirely sure we want to want to bootstrap a new project using these libraries as opposed to migrating off of them. My question is this: how important is the pastedeploy framework and the paste.ini files nowadays, particularly for deployers? While their use is relatively consistent across projects (see below), not every service uses them and for those that don't, I personally haven't heard complaints about their absence. Rather than migrating the pastedeploy stuff elsewhere, would it make more sense for affected projects to simply define a static set of middleware (with some config knobs for those we want to be able to enable/disable) and call it a day? Cheers, Stephen PS: This topic came up about 18 months ago [6], but we don't appear to have reached a conclusion. Thus my bringing it up again. [1] https://review.opendev.org/c/openstack/oslo.service/+/954055 [2] https://pypi.org/project/Paste/#history [3] https://pypi.org/project/PasteDeploy/#history [4] https://pypi.org/project/Routes/#history [5] https://pypi.org/project/WebOb/#history [6] https://lists.openstack.org/archives/list/openstack-discuss@lists.openstack… --- fwict, the following services all rely on this combo to build their own frameworks, with Nova most likely the progenitor in each case (I'm guessing) * Nova * Barbican * Cinder * Designate * Freezer * Glance * Heat * Manila * Monasca * Neutron * Swift * Trove * Vitrage * Watcher The following services do *not* use these libraries: * Cyborg (pecan) * Ironic (pecan) * Keystone (Flask + Flask-RESTful, with some webob) * Magnum (pecan) * Masakari (homegrown framework using webob) * Zaqar (falcon) * Zun (Flask)

[Kolla] Looking for a Support Provider
by Buddhika S. Godakuru - University of Kelaniya 17 Jul '25

Hi All, We are a University in Sri Lanka, and we have a small Openstack (2023.1) deployment using Kayobe. The on-prem cloud is currently operational, but currently there is only one member who has the idea about the design, and implementation of hardware/OS/configuration/network setup. So the management is trying to find an additional entity who can support in an emergency, as well as to avoid being dependant on a single person. Are there any person/institute/person who can support our setup (not day to day activities) in case of service/hardware failure, preferably within Sri Lanka. Thank you -- බුද්ධික සංජීව ගොඩාකුරු Buddhika Sanjeewa Godakuru Systems Analyst/Programmer Information and Communication Technology Centre (ICTC) University of Kelaniya, Sri Lanka, Kelaniya, Sri Lanka. -- **** *University of Kelaniya, Sri Lanka, accepts no liability for the content of this email or for the consequences of any actions taken on the basis of the information provided unless that information is subsequently confirmed in writing. * *If you are not the intended recipient, this email and/or any information it contains should not be copied, disclosed, retained or used by you or any other party, and the email and all its contents should be promptly deleted fully, and the sender informed. * ** ** *E-mail transmissions cannot be guaranteed to be secure or error-free as information could be intercepted, corrupted, lost, destroyed, arrive late or incomplete. * ****

Re: [cinder] How to retype while maintaining volume usage
by Yuta Kambe (Fujitsu) 16 Jul '25

Hi Eugen, Thank you for your reply. I've confirmed that 'rbd sparsify' can increase available space. However, I believe there's room for improvement in the retype implementation. Currently, retyping between Ceph backends causes zero-filling, which unnecessarily consumes time and storage space. This is likely to happen frequently, for example, with retypes between Ceph's HDD and SSD backends, and the Ceph administrator would need to run 'rbd sparsify' frequently. Are there any improvements to the retype implementation being considered in the community? I would also appreciate hearing your opinion on the need for improvement. Best regards,
