Hi all, does anyone know if NVMe over RDMA is supported to attach it with Cinder/Nova to a QemuKVM Hypervisor? In addition to our ceph, we would also like to connect a block storage and in order to be able to retrieve the full performance, this must be done with the above-mentioned connection. Thanks in advance. Holger

Cinder volume service and high availability question
by Jim Kilborn 18 Feb '25

18 Feb '25

Hello, I am trying to figure out how to get cinder volume service to use a virtual name for the cinder volume host. We have three controllers that are setup with keepalived and haproxy with a virtualized servername that is used in the various openstack .conf files. This allows either server to shutdown and we can still access the web interface, create vms and volumes, etc. because the virtual hostname is used in all the configurations. However, for cinder volumes, it puts the hostname of the server in os-vol-host-attr:host rather than my virtual name. This causes issues if the controller that was used to create the volume is down, we can't easily manage the volume without modifying that field in the cinder database. If the virtual name could be used, either server could manage the volume with the backend, with no manual changes to the db. The only server related setting in my cinder.conf is my_ip, and that is the ip of the actual server, not the virtual ip Is active/active cluster not supported with cinder?

[horizon] Automatic refresh of page elements/content
by dbarrosf＠windriver.com 18 Feb '25

18 Feb '25

Hi everyone, I would like to query about implementing a feature: Automatic refresh of page elements/content on openstack dashboard (horizon). I'm a developer working on starlingx dashboard (gui) project, which is based on openstack dashboard. We noticed that all content on starlingx dashboard doesn't get updated if a change occurs. So, as a workaround, a full page reload is required. We have added a patch to customize horizon package and enable automatic refresh in some of the content. But this is not a definitive solution, since it doesn't solve auto refresh for all page elements/content: https://review.opendev.org/c/starlingx/upstream/+/941145 We also noticed errors on browser's console related to mutation events, although I'm not sure this is relevant for the discussion: https://bugs.launchpad.net/horizon/+bug/2098785 Do you have any plans to add such a feature? Or should we submit a blueprint? Thank you for your time. Regards, Davi Frossard

As I researched there is no solution for backing up openstack virtual machines. What is the best way to organize BaaS on openstack environment? I have used snapshots and converted them to images, but this is not production solution. Thank you for your support

[octavia] Blocking a specific network for the VIP of LBs
by Thomas Goirand 18 Feb '25

18 Feb '25

Hi there! In our setup, we offer to our customers, on top of floating IPS, access to an OpenStack internal network that contains public IPs. The idea is that they can, using this network, spawn VMs with a public IP directly on the NIC of their VMs. The issue is, some customers also use this network for the VIP of their LBs. While this seems to work, actually, instead of reserving a single public IP address, it reserves 3 IPs. Not a big deal for us, as they are billed internally, though it's rather bad for our customers. On top of that, whenever one of the subnet of this network becomes full, it becomes impossible to failover amphoras spawned in this subnet. Each time one runs into ERROR, it's kind of a bad situation where we have no way to fix, except contacting the customer and ask them to fix their setup. So we advise our customers to spawn a port first, use that port for the LB, and associate a floating IP address to the original port. This is described in our doc here: https://docs.infomaniak.cloud/network/loadbalancer_usecase_simple_http/ However, as you may know, customers never read the docs. And therefore, we'd like to forbid the use of that shared OpenStack internal network for the VIP of LBs. But as much as possible, this isn't a feature of Octavia. Is it? I'd like to implement the feature. What's the best way to do so? Would a new "forbidden_networks" directive would do, and then have a check at the API level? Or is there a better way using the API policy? Also, wouldn't it be possible that Octavia just reuse the ports that it currently hold, rather than asking new ports for the failover? If so, any clue where the code that does that could be fixed? I'd love to have this fixed AND the forbid network feature too... Cheers, Thomas Goirand (zigo)

[tc][election] mnasiadka TC candidacy for 2025.2
by Michał Nasiadka 18 Feb '25

18 Feb '25

Hello, I'd like to announce my candidacy for the Technical Committee. This is would be my first TC term (I have never applied for a TC seat). My relations with OpenStack started around Liberty release as a user and Ocata as a Kolla developer. Since Yoga release I became PTL for Kolla (that also includes Kolla-Ansible and Kayobe). I'm also a core reviewer for the Magnum project and diskimage-builder. Throughout my commercial career I've been working with OpenStack clouds in service provider (including VMware and Microsoft hypervisors managed by OpenStack), telco and HPC environments - which give me a broad view of the different use cases for running a cloud. Due to my PTLship of a deployment project - I will probably be focused on operators' perspective and cloud managability aspects - which if possible I'd like to improve - and by that also improve the overall experience of using OpenStack. Thank you for considering my candidacy, Regards, Michal Nasiadka

Issues with installing Zun on Compute node
by Milan M 18 Feb '25

18 Feb '25

I was trying to install openstack 2024.2 zun on compute node. and following the page https://docs.openstack.org/zun/2024.2/install/compute-install.html for installation. I am facing the issue of docker "--cluster-store" support. I am using Docker 27.5 version. Reading the documentation online, i am confused. Some places it is, mentioned that it is fixed. and some places it suggest to uses docker 22. At few places in your mail you have mentioned to stop using kuryr and use CNI. And official documentation still says to use --cluster store. What is the current state and the correct solution. Please guide me.
