[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

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. * ****

[cinder] IBM SVf driver callhome
by Vivek Pandey 16 Jul '25

16 Jul '25

Hi Joe/ Brian, Since we didn’t get a chance to discuss the patch [IBM SVf driver] Adding support for callhome plugin, we can continue the conversation here. Patch : https://review.opendev.org/c/openstack/cinder/+/951829. We need callhome enabled as default for which we have introduced a parameter “callhome” in cinder.conf. This feature is to fecth the os_version, cinder-manage version and ispbhaenabled. Note: We are not fetching any customer’s sensitive data. Please let me know if you’ve had a chance to review NetApp’s ActiveIQ implementation. Netapp’s ActiveIQ code ref : https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/netap… As we have discussed during the 9th July cinder call, Anoop from NetApp confirmed that they are enabling it by default and EMS details are being captured from the logs. Based on that, do you think we can align or extend our current IBM callhome implementation (from the patch above) to follow a similar approach? Thanks, Vivek

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

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,

[nova] Information Sharing for Arm CCA Feature (Following 4/8 PTG)
by taketani.ryo＠fujitsu.com 14 Jul '25

14 Jul '25

Thank you for the productive discussion about Arm CCA feature [1] at the PTG on April 8th. > The use case for Arm CCA looks ok. But it is a bit early. It is wise to wait at least libvirt / qemu release to have a "stable" code. > We may want to have a OS distribution version (such as Ubuntu XX.YY) which supports Arm CCA so that users can actually use/test the feature The above information is quoted from the PTG Etherpad [2](L316) summary. I'd like to follow up on these points. I'd like to share relevant information about Arm CCA surrounding components (libvirt, QEMU, OS Distributions(e.g., Ubuntu xx.xx), hardware) as it becomes available, and proceed with the discussion step by step.. I'm starting with this email, but if there's a more appropriate method for sharing this type of information, please let me know. Here's the Arm CCA software components information I can share at this time: * Linux Kernel: The roadmap is outlined on the fifth page of the third attachment in this link [3]. The initial commits I've proposed to OpenStack are focused on RMM 1.0. KVM host support for RMM 1.0 will be available in H2 2025. * QEMU Upstream Status: The development is in-progress, awaiting the Linux Kernel merge * libvirt Upstream Status: The development is in-progress, awaiting the QEMU merge * OS Distribution Support: The road map is not clear now > We may want to have a OS distribution version (such as Ubuntu XX.YY) which supports Arm CCA so that users can actually use/test the feature I have a question regarding the above. For design discussions leading to spec approval, I understand that upstream QEMU/libvirt stable release is necessary. Is a specific OS distribution release (e.g., Ubuntu xx.xx) also required for spec approval?
