[tc][all][monasca] Retiring the Monasca project and repositories
by Goutham Pacha Ravi 07 Aug '25

07 Aug '25

Hello Stackers, We intend to retire the Monasca project [1] and all associated repositories [2]. The retirement is being proposed with the support and consent of the current core team members and the Project Team Lead (PTL) [3]. For context, the Monasca project team was marked as being inactive during the 2024.1 (Caracal) release cycle [4]. Since then, no sustained development activity has occurred. There have been no releases tagged for any of the deliverables owned by the team either, and there are no actively maintained stable branches. So, in accordance with the procedures in the OpenStack governance documentation [5], and based on the current state of the project, we propose the following repositories ahead of the 2025.2 ("Flamingo") coordinated release: - openstack/monasca-agent - openstack/monasca-api - openstack/monasca-common - openstack/monasca-events-api - openstack/monasca-log-api - openstack/monasca-notification - openstack/monasca-persister - openstack/monasca-specs - openstack/monasca-tempest-plugin - openstack/monasca-thresh - openstack/python-monascaclient - openstack/monasca-ui - openstack/monasca-transform - openstack/monasca-ceilometer - openstack/monasca-grafana-datasource - openstack/monasca-kibana-plugin - openstack/monasca-statsd Some of the current maintainers intend to fork the project and continue development independently for their purposes. This retirement does not preclude such efforts; nor does it prevent reviving the project after the retirement. If there are any objections to retiring the project, please respond to this thread. In the event there is interest in continuing Monasca within OpenStack, we would expect the project team to meet the requirements for active status [6] — including identifying a new PTL for the upcoming release cycle and demonstrating plans for sustained maintenance. Thank you to everyone who has contributed to Monasca over the years. Thanks, On behalf of the OpenStack TC, Goutham Pacha Ravi (gouthamr) OpenStack TC Chair [1] https://docs.openstack.org/monasca-api/latest/ [2] https://github.com/openstack/governance/blob/624bb5bf124452eed475c9b6e62144… [3] https://review.opendev.org/c/openstack/governance/+/953671 [4] https://governance.openstack.org/tc/reference/emerging-technology-and-inact… [5] https://docs.openstack.org/project-team-guide/repository.html#retiring-a-re… [6] https://governance.openstack.org/tc/reference/new-projects-requirements.html

[dev][designate] PSA: pkg_resources is broken with newer oslo wheels on Python 3.8
by Stephen Finucane 07 Aug '25

07 Aug '25

o/ A quick PSA for a topic has come up in a few different OpenStack forums of late. As described in a recently filed setuptools bug [1], the pkg_resources found in the most recent version of setuptools to support Python 3.8 does not correctly normalize package names passed to `pkg_resources.require`. This has become an issue of late because since earlier this year the OpenStack release tooling has started (correctly) normalizing filenames of the '.whl' files uploaded to PyPI (so e.g. 'oslo.messaging' now becomes 'oslo_messaging'). You are likely to see this manifest with weird errors like `The 'package.foo>=1.2.3' distribution was not found`, when you know that it is. I have seen it pop up because either (a) pkg_resources is being invoked via an explicit call, as in some of the release tooling used in `openstack/releases`, or (b) pkg_resources is being invoked via the auto-generated import headers added by setuptools when you use its legacy "scripts" keyword rather than newer "console scripts" replacement. The latter in particular is biting some projects indirectly due to Designate and Octavia incorrectly using this mechanism to work around the demise of wsgi_scripts, and I have fixes up waiting for review [2][3]. Just sharing in case some people have seen this, because it's quite a weird corner case to hit.

[cinder] IBM SVf driver callhome
by Vivek Pandey 06 Aug '25

06 Aug '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

[all][ops][qa] Decommissioning RefStack and retiring related software
by Jeremy Stanley 05 Aug '25

05 Aug '25

The RefStack service at refstack.openstack.org has been unused for purposes of qualifying OpenStack trademark licenses[*] since March of last year, after a 2023 board resolution[**] relaxed the former requirement for it. Effective immediately, the service is being decommissioned along with any associated resources, and the related Git repositories in OpenDev (interop, refstack, refstack-client) will be officially retired in the near future as well. Let me know if you have any questions or concerns.

[kolla][barbican] Secure password management in Kolla-Ansible using Castellan
by elnazcloud＠gmail.com 05 Aug '25

05 Aug '25

Hi all, I have deployed an OpenStack environment using Kolla Ansible. I'm looking for a way to avoid storing service passwords (e.g., database, keystone, etc.) in clear text inside the configuration files. Is there any recommended method to integrate Barbican and Castellan so that services like Nova, Keystone, or Cinder can fetch secrets securely during runtime using oslo.config? If not natively supported, are there best practices or known workarounds for achieving this securely in a Kolla-based deployment? Thanks in advance!

[Zed][Neutron][OVN] Severe VM Network Performance Degradation Compared to Host
by Jeff Yang 05 Aug '25

05 Aug '25

Hi all, I'm running OpenStack Zed with OVN as the Neutron backend. I've encountered a severe VM network performance degradation issue and would appreciate any insights from the community. 🔹 **Environment** - OpenStack version: Zed - Neutron backend: OVN - Two VMs (each 4 vCPUs, 8 GB RAM) launched on two different compute nodes - Multi-queue is enabled on the VM vNICs 🔹 **Issue** The network performance inside the VMs is significantly worse than on the host nodes, with high packet retransmissions observed. 🔹 **Test results** **Host-to-Host (VTEP IPs)** ``` $ iperf3 -c 192.168.152.152 Connecting to host 192.168.152.152, port 5201 [ 5] local 192.168.152.153 port 45352 connected to 192.168.152.152 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 1.38 GBytes 11.8 Gbits/sec 0 3.10 MBytes [ 5] 1.00-2.00 sec 1.37 GBytes 11.8 Gbits/sec 0 3.10 MBytes [ 5] 2.00-3.00 sec 1.42 GBytes 12.2 Gbits/sec 0 3.10 MBytes [ 5] 3.00-4.00 sec 1.39 GBytes 11.9 Gbits/sec 0 3.10 MBytes [ 5] 4.00-5.00 sec 1.38 GBytes 11.8 Gbits/sec 0 3.10 MBytes [ 5] 5.00-6.00 sec 1.43 GBytes 12.3 Gbits/sec 0 3.10 MBytes [ 5] 6.00-7.00 sec 1.41 GBytes 12.1 Gbits/sec 0 3.10 MBytes [ 5] 7.00-8.00 sec 1.41 GBytes 12.1 Gbits/sec 0 3.10 MBytes [ 5] 8.00-9.00 sec 1.41 GBytes 12.1 Gbits/sec 0 3.10 MBytes [ 5] 9.00-10.00 sec 1.42 GBytes 12.2 Gbits/sec 0 3.10 MBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 14.0 GBytes 12.0 Gbits/sec 0 sender [ 5] 0.00-10.04 sec 14.0 GBytes 12.0 Gbits/sec receiver iperf Done. ``` **VM-to-VM (through overlay network)** ``` $ iperf3 -c 10.0.6.10 Connecting to host 10.0.6.10, port 5201 [ 5] local 10.0.6.37 port 56710 connected to 10.0.6.10 port 5201 [ ID] Interval Transfer Bitrate Retr Cwnd [ 5] 0.00-1.00 sec 499 MBytes 4.19 Gbits/sec 263 463 KBytes [ 5] 1.00-2.00 sec 483 MBytes 4.05 Gbits/sec 467 367 KBytes [ 5] 2.00-3.00 sec 482 MBytes 4.05 Gbits/sec 491 386 KBytes [ 5] 3.00-4.00 sec 483 MBytes 4.05 Gbits/sec 661 381 KBytes [ 5] 4.00-5.00 sec 472 MBytes 3.95 Gbits/sec 430 391 KBytes [ 5] 5.00-6.00 sec 480 MBytes 4.03 Gbits/sec 474 350 KBytes [ 5] 6.00-7.00 sec 510 MBytes 4.28 Gbits/sec 567 474 KBytes [ 5] 7.00-8.00 sec 521 MBytes 4.37 Gbits/sec 565 387 KBytes [ 5] 8.00-9.00 sec 509 MBytes 4.27 Gbits/sec 632 483 KBytes [ 5] 9.00-10.00 sec 514 MBytes 4.30 Gbits/sec 555 495 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bitrate Retr [ 5] 0.00-10.00 sec 4.84 GBytes 4.15 Gbits/sec 5105 sender [ 5] 0.00-10.05 sec 4.84 GBytes 4.14 Gbits/sec receiver iperf Done. ``` As you can see, there's a sharp drop in performance inside the VMs (from ~12 Gbps down to ~4 Gbps), with a lot of retransmissions in 10 seconds. Has anyone encountered a similar issue with OVN and VM networking performance? What could be the potential causes? Any suggestions or debugging tips are welcome. Thanks in advance! Best regards,

[Neutron] - General thoughts on tenancy network MTU
by Karl Kloppenborg 01 Aug '25

01 Aug '25

Hi Neutrinos, I was discussing with a colleague about our MTU settings within our Openstack regions, generally speaking we have a physnet_global_mtu of 1550 with tenancy networks automatically provisioned as 1500 VXLAN. This ends up with VM’s receiving DHCP MTU settings of 1500 which is fine, however reading about yesterday’s discussion on OVN performance, Nguyen’s recommendation was to enable Jumboframes. This got me thinking, what do you set your tenancy and phynet MTU’s to? Very interested to hear about your experiences with running 9k MTU’s on the VM networks etc, what impact this has on OVS/OVN routers and northbound connectivity being 1500. Thanks, Karl.

[scientific-sig][help] Research about private cloud
by Winicius Allan 01 Aug '25

01 Aug '25

Hi all! I'm about to write my final paper, and I want to research something related to OpenStack and private clouds. If someone wants to take the time to discuss the problems in your environment, I'd be very glad!What I had on my mind is: - There is something that could improve utilization and performance when the user is not charged about their use on a private cloud. - There is any process scheduling algorithm that could be used on specific workloads instead of Linux default scheduler that can improve application performance? I was thinking about using eBPF here. Best regards.
