[Neutron] DHCP port status inactive
by Vinicius Afonso 16 Dec '24

16 Dec '24

Hello, I am new to Openstack environment and I need help with a Neutron problem. When I create a new network, the DHCP port launches with status inactive. Even though I tried to create a VM, the DHCP generate a port for the machine, However it takes a few minutes to give an error: "Build of instance ed6c8835-f2d4-4730-9638-74ded388361b aborted: Failed to allocate the network(s), not rescheduling." The only alternative solution to overcome this issue is to change the DHCP agent of the network. If I change it, the new DHCP port will have an active status and then I can launch a VM. Nothing conclusive was found in the logs, just the error to bind the port. It doesn't say anything to why the port is inactive, just that the port was created and with status active. Things that I already tried: -> See nova and neutron logs -> Restart neutron-server, neutron-dhcp-agent, neutron-openvswitch-agent -> Change manually the DHCP agent Anyone had the same problem as this one? Any tips to troubleshoot? Any help is welcome! Thanks.

Dalmatian: Dimensions of instance console
by berndbausch＠gmail.com 15 Dec '24

15 Dec '24

This is a Dalmatian-based Devstack. The instance console's height is too large for my screen. Documentation claims that console dimensions can be configured in a file named _detail_vnc.html [1], but there is no file with this name anywhere in the filesystem. I just submitted a bug [2] but wonder if somebody can help me out right now. How can the console dimensions be configured? Thanks! Bernd Bausch Instructor and tinkerer Here is my bug description: Under Frequently Asked Questions (https://docs.openstack.org/nova/2024.2/admin/remote-console-access.html#fre quently-asked-questions), the answer to Q: How do I adjust the dimensions of the VNC window image in the OpenStack dashboard? is incorrect. My Devstack installation contains no file named _detail_vnc.html. I found a file with the interesting name _detail_console.html under /opt/stack/horizon/openstack_dashboard/dashboards/project/instances/template s/instances, but it doesn't contain the answer's code for width and height.

[tc][all] OpenStack Technical Committee Weekly Summary and Meeting Agenda (2025.1/R-15)
by Goutham Pacha Ravi 15 Dec '24

15 Dec '24

Hello Stackers, We're 15 weeks away from the 2025.1 ("Epoxy") release date (2024-04-02) [1]. During the last week, the Technical Committee continued discussing the state of "unmaintained" code branches across OpenStack repositories and election officials proposed dates for the combined TC+PTL elections for the next release cycle [2]. We have decided to cancel the weekly meetings previously scheduled for 24th December and 31st December in lieu of the holidays. === Weekly Meeting === The OpenStack Technical Committee met over IRC on 2024-12-10 [3]. We revisited challenges with using CentOS 10 in the community CI system due to lack of AVX/AVX2 CPU flags on current cloud providers. Discussions revolved around finding providers with suitable hardware or reducing reliance on CentOS testing. We then revisited the state of "unmaintained" branches across OpenStack repositories. The oldest "unmaintained" branch tracks the "victoria" release (GA: 2020-10-14). The consensus amongst TC members was to enforce the policy to default old branches to EOL unless explicitly opted-in with required maintenance assurances. To do this, we need tooling to automate the transition, and a way to track and validate volunteer opt-ins for unmaintained branches. Volunteers stepped up to transition branches up until the 2023.1 ("Antelope") release to "end-of-life", beginning with the Victoria release branch [4]. If you're interested in keeping a particular branch open, for any repository, please express your interest directly on the gerrit change. All EOL transition patches will be merged after 1 month of community review. The next meeting of the OpenStack Technical Committee is on 2024-12-17 at 1800 UTC. This meeting will take place in the #openstack-tc channel on OFTC's IRC server. Please find the meeting agenda on the wiki [5]. Please remember that you can propose topics for upcoming TC meetings by directly editing the wiki. If you're unable to do so, please holler at me (IRC nick: gouthamr) or in the TC's IRC channel (#openstack-tc). === Governance Proposals === ==== Merged ==== - Retire Murano/Senlin/Sahara OpenStack-Ansible roles | https://review.opendev.org/c/openstack/governance/+/935677 ==== Open for Review ==== - Add ansible-role-httpd repo to OSA-owned projects | https://review.opendev.org/c/openstack/governance/+/935694 - Rework the initial goal proposal as suggested by people | https://review.opendev.org/c/openstack/governance/+/931254 - Resolve to adhere to non-biased language | https://review.opendev.org/c/openstack/governance/+/934907 - Propose to select the eventlet-removal community goal | https://review.opendev.org/c/openstack/governance/+/934936 - Allow more than 2 weeks for elections | https://review.opendev.org/c/openstack/governance/+/937741 === How to Contact the TC === You can reach the TC in several ways: - Email: send an email with the tag [tc] on this mailing list. - IRC: Ping us using the tc-members keyword on the #openstack-tc IRC channel on OFTC. - Weekly Meeting: The Technical Committee meets every week on Tuesdays at 1800 UTC [5].

Diagnosing Sluggish Instance Boot Performance in OpenStack Cluster
by Abhijit Singh Anand 14 Dec '24

14 Dec '24

Dear All, Problem Statement: Instances remain stuck in the “Block Device Mapping” state for an extended period (~9 minutes) before eventually booting. This issue is observed consistently in one of my OpenStack clusters, while another cluster built on similar hardware and configuration spins up instances much faster. Environment Details: 1. Cluster Configuration: * Deployed using Kolla-Ansible on similar hardware specifications. * Both clusters connect to a common Ceph SSD-backed storage cluster. * Connection: 20 Gbps bonded interface over Cisco Nexus switches. * Same volumes used for images, VMs, backups. * Ceph keyrings and configurations are identical. 2. Performance Comparison: * “Good” cluster: Instances (even with large images >20 GB) boot to a login prompt in ~1-2 minutes. * “Bad” cluster: Instances with the same images and size take ~8-9 minutes. 3. Storage Backend Architecture: * “Good” cluster: Cinder-volume service is co-resident on compute nodes. * “Bad” cluster: Cinder-volume service runs only on controller nodes. 4. Instance Images: * Performance issue occurs with both RAW and QCOW2 images. * Example: A Windows 10 Pro RAW image boots in 1 min 40 sec in the "Good" cluster and takes 8 min 45 sec in the "Bad" cluster. What I’ve Tried So Far: * Configuration Matching: Reviewed and aligned as many configuration parameters as possible between the two clusters. * Resource Monitoring: Verified CPU and memory usage on nodes during instance launches—no significant resource contention observed. * Ceph Performance: Checked Ceph cluster performance; it seems healthy with no latency or throughput issues. * Network Testing: Verified 20 Gbps bond interfaces on both clusters; no observed bottlenecks. Hypothesis: I suspect the cinder-volume architecture could be contributing to the issue. In the "Good" cluster, cinder-volume is co-located with compute nodes, possibly optimizing data transfer paths. In contrast, the "Bad" cluster relies solely on controller-hosted cinder-volume services, which might introduce delays in data availability to compute nodes. Request for Community Input: 1. Does the difference in the placement of the cinder-volume service (co-resident vs. controller-only) align with the observed performance discrepancy? 2. Could there be other subtle configuration or architectural nuances that might explain the delays in the "Bad" cluster? 3. What specific logs or metrics would be most insightful in diagnosing this issue further? * I’ve reviewed Nova and Cinder logs but could dive deeper if pointed in the right direction. 4. Are there recommended best practices for tuning Cinder, Nova, or Ceph for environments with high storage performance requirements? Thank You! I appreciate any insights, suggestions, or pointers you can provide to help narrow down the root cause of this frustrating performance discrepancy. Regards, Abhijit S Anand

[release] Release countdown for week R-15
by Thierry Carrez 13 Dec '24

13 Dec '24

Development Focus ----------------- The Epoxy-2 milestone will happen next month, on January 9th, 2025. 2025.1 "Epoxy"-related specs should now be finalized so that teams can move to implementation ASAP. Some teams observe specific deadlines on the second milestone (mostly spec freezes): please refer to https://releases.openstack.org/epoxy/schedule.html for details. General Information ------------------- Please remember that libraries need to be released at least once per milestone period. At milestone 2, the release team will propose releases for any library that has not been otherwise released since milestone 1. Other non-library deliverables that follow the cycle-with-intermediary release model should have an intermediary release before milestone-2. Those who haven't will be proposed to switch to the cycle-with-rc model, which is more suited to deliverables that are released only once per cycle. At milestone-2 we also freeze the contents of the final release. If you have a new deliverable that should be included in the final release, you should make sure it has a deliverable file in: https://opendev.org/openstack/releases/src/branch/master/deliverables/epoxy You should request a beta release (or intermediary release) for those new deliverables by milestone-2. We understand some may not be quite ready for a full release yet, but if you have something minimally viable to get released it would be good to do a 0.x release to exercise the release tooling for your deliverables. See the MembershipFreeze description for more details: https://releases.openstack.org/epoxy/schedule.html#e-mf Finally, now may be a good time for teams to check on any stable releases that need to be done for your deliverables. If you have bugfixes that have been backported, but no stable release getting those. If you are unsure what is out there committed but not released in the openstack/releases repo, running the command "tools/list_stable_unreleased_changes.sh <cycle_name>" gives a nice report. Upcoming Deadlines & Dates -------------------------- Epoxy-2 Milestone: January 9th, 2025 2025.1 Epoxy final release: April 2nd, 2025 -- Thierry Carrez (ttx)

[cinder][ceph rbd driver] create volume in EC pool by download, but not clone
by Tony Liu 12 Dec '24

12 Dec '24

Hi, With Antelope, when create a volume in EC pool from image, Cinder downloads the image and upload it to volume, instead of cloning it as create volume in replicated pool. May I know the intention behind it? Why not clone it? Also, in case the intention is to remove dependency, clone and flatten works better. Thanks! Tony

[nova][tc] Removing md5 in password injection
by Thomas Goirand 12 Dec '24

12 Dec '24

Hi, I didn't feel it would be controversial, though it seems removing md5 password injection is still up to debate: https://review.opendev.org/c/openstack/nova/+/935512 Of course, I'd like the TC to agree with me that injecting md5-hashed passwords is, in 2024, to be considered a security problem that should be fixed (and backported) ASAP. BTW, IMO this patch could be using the new feature from oslo_utils.secretutils that Takashi managed to get in: https://review.opendev.org/c/openstack/oslo.utils/+/931899 https://review.opendev.org/c/openstack/oslo.utils/+/935525 These, IMO, should also be backported to earlier oslo.utils releases, so we can fix earlier OpenStack releases in a nicer way. Cheers, Thomas Goirand (zigo)

Hi, With Antelope, old volume type is on replicated pool and new volume type is on EC pool. Change volume type doesn't work, volume type remains and no error returns. Is such change supported? I also tried change volume type from one replicated pool to another replicated pool. Doesn't work either. Am I missing anything? Thanks! Tony

[Openstack-ansible][Rabbitmq] Rabbitmq role is installing latest version of rabbitmq even after setting package version in variable file
by Danish Khan 12 Dec '24

12 Dec '24

Dear All, I have upgraded few of my openstack clusters from Ussuri to Wallaby successfully. But it seems rabbitmq repo is changed and now rabbitmq is getting its packages from: https://dl.cloudsmith.io/public/rabbitmq/rabbitmq-server/deb/ubuntu Everything was working fine until I face below issue while running rabbitmq playbook: TASK [rabbitmq_server : Apply rabbitmq policies] ******************************************************************************************************* failed: [rabbit_mq_container] (item={'name': 'HA', 'pattern': '^(?!(amq\\.)|(.*_fanout_)|(reply_)).*', 'priority': 0, 'tags': 'ha-mode=all'}) => {"ansible_loop_var": "item", "changed": false, "cmd": "/usr/sbin/rabbitmqctl -q -n '' set_policy -p / HA '^(?!(amq\\.)|(.*_fanout_)|(reply_)).*' '{\"ha-mode\": \"all\"}' --priority 0", "item": {"name": "HA", "pattern": "^(?!(amq\\.)|(.*_fanout_)|(reply_)).*", "priority": 0, "tags": "ha-mode=all"}, "msg": "Error:\nValidation failed\n\n[{<<\"ha-mode\">>,<<\"all\">>}] are not recognised policy settings", "rc": 69, "stderr": "Error:\nValidation failed\n\n[{<<\"ha-mode\">>,<<\"all\">>}] are not recognised policy settings\n\n", "stderr_lines": ["Error:", "Validation failed", "", "[{<<\"ha-mode\">>,<<\"all\">>}] are not recognised policy settings", ""], "stdout": "", "stdout_lines": []} It seems ha-mode=all is deprecated in latest version of Rabbitmq (4.0.4). I tried to install 3.8 or some other compatible version of rabbitmq but anyway the latest version of rabbitmq is getting installed. I have updated below entries of file /etc/ansible/roles/rabbitmq_server/vars/debian.yml : _rabbitmq_package_version: "3.8.14-1" and _rabbitmq_erlang_version_spec: "{{ (rabbitmq_install_method == 'external_repo') | ternary('1:23.3.4.15-1', '1:22.*') }}" Can someone please help me with this? I guess either I need to find a away to install specific version of rabbitmq to fox rabbitmq policy issue or I need to update parameters of command while applying policy. Regards, Danish Khan

Nothing else comes to mind. Basically it's the desire to avoid ToFU style finger-crossing that the SSH host key you get on initially connecting to a newly booted server instance is really coming from that instance and not a MitM or honeypot. It's possible in most providers to create an authenticated backchannel by abusing the console log, as I described, but that has its own challenges. I suppose there might be alternative management protocols similar to SSH which rely on asymmetric key algorithms to authenticate hosts, but I'm not personally familiar with any (none with the near ubiquity of SSH at any rate). > perhaps we can try and capture this is a spec or separate thread > and work out what an mvp would look like. there would basically be > two part, one extednign the metadata api to support recording the > host key fingerprint somewhere, and then making that discoverable > via the main api perhaps in server show. That would make sense, and it would probably also be a good idea to try to involve e.g. a cloud-init maintainer in any such design discussion, as this would need client-side integration eventually anyway in whatever's going to communicate the key back to nova. > is we allowed read write access to all instance metadata we would > would not actually need to modify the main api as you can already > list metadata on an instance but im worried that could be abused > so i don't know if that is a good idea.

Agreed, I suppose the field could be given a more generic name in case certain kinds of guests wanted to store functionally similar things in it, but as I said I don't know what else that would end up being anyway. -- Jeremy Stanley

Some questions about ironic
by Johnny Hao 11 Dec '24

11 Dec '24

Hi Buddies, I am new to ironic, after some study, I have several questions about it, could anyone help to answer? Thanks a lot. 1. According to the workflow chart below, what's the communication method between nova-compute and Ironic API? HTTP API call or RPC call through mq like rabbitmq? So are the communications between Ironic Conductor and other components of Neutron, Glance and Cinder/Swift etc? 2. Where do Ironic services run (Ironic API/Conductor/Drivers and DB)? In the controller node? Or a separate node is also supported? ** -- Best regards QingFeng Hao

[nova] riscv64 emulation support
by James Page 11 Dec '24

11 Dec '24

Hi Nova Team We've had some initial support for enabling RISCV64 support in Nova in a review for sometime which I refreshed this week: https://review.opendev.org/c/openstack/nova/+/889137 Sean suggested that this really needs a blueprint and discussion at the next Nova meeting (which I can't make) so proposing discussion via ML instead: https://blueprints.launchpad.net/nova/+spec/riscv64-emulation-support I'm also going to look at the nova-emulation job to see if that can be extended to cover RISCV64 as well - there are a few nuances with dependent packages (opensbi) in Ubuntu 24.04 but I think we can come up with something workable for testing. Review and comments are appreciated. Thanks James

OpenStack metrics and logs
by Timothé Bauge 11 Dec '24

11 Dec '24

Hello Stackers, I would like to know what are you all using to monitor and supervise your Openstack clusters ? We are in the process of setting up our own private cloud based on RedHat OpenStack Platform 17.1, we choose not to go with the RedHat Service Telemetry Platform, and were strongly advise against Ceilometer and aodh. At the moment, we built our own stack based on Prometheus (with the plenty of exporters) for the metrics, Graylog + OpenSearch for the logs, and Grafana for the visualisation. For now, we are only looking to retrieve basic information in order to know if a dysfunction occurs, but the end goal might be to go as far as to be able to count the cpu/mem/disk usage per hour per vm per project, etc. So, what are you all using and how did you implement it ?

Hello, We want to fetch all the servers present in all the projects a user has access to. Currently we have to provide any one project name in the body of the authentication call. Is there a way we can fetch all the projects without providing any project name?
