[oslo][docs] Request to release openstackdocstheme
by Camp, MaryX 16 Sep '21

16 Sep '21

Hi to the Oslo team, Can you please release the openstackdocstheme so it can be used by the StarlingX community? This will correct the double headings issue we see now on every doc page. We've made similar historical release requests for 2.2.4 [1], 2.2.5 [2], and 2.2.7 [3] The StarlingX docs site utilizes a theme variant within the openstackdocstheme repo, but consumes packaged releases. Several recent changes merged to address Sphinx 4.x changes, and the StarlingX community would appreciate a new openstackdocstheme release to make use of them. [1] 2.2.4 https://review.opendev.org/c/openstack/releases/+/737105 [2] 2.2.5 https://review.opendev.org/c/openstack/releases/+/741550 [3] 2.2.7 https://review.opendev.org/c/openstack/releases/+/765192 Thanks in advance!

[neutron][networking-midonet] Propose to EOL stable/pike, stable/queens and stable/rocky branches of networking-midonet
by Lajos Katona 16 Sep '21

16 Sep '21

Hi, The older than rocky branches of networking-midonet are broken, as it seems that the last merge on stable/rocky and stable/queens happened a year ago, and even the master branch of networking-midonet is not maintained. Considering the above I propose to make stable/rocky, stable/queens, stable/pike branches End Of Life. I will wait until the end of next week for anyone who would like to maybe step up as maintainer of those branches and who would at least try to fix CI of them. If there will be no volunteers for that, I will EOL those branches in networking-midonet. Lajos Katona (lajoskatona)

Neutron
by Zeeshan Haider 16 Sep '21

16 Sep '21

**Scenario**: We are trying to develop our Virtual Network using `Open Virtual Network` or `OVN`, We need our Virtual Network Switches running firstly on the root Virtual Router, and there are some other Virtual Switches as well. I was Working on the `openvswitch` and `OVN` but a lot of things are missing for me, and there are some unlinked dots between the deployment itself and there are some problems. My Question has 3 further Parts. 1. Is it possible at all to use `Neutron` as our Network Manager without OpenStack cloud installation? 2. Is it a good approach? 3. if not then are there any cookbooks available for `OVN`, I am not talking about man-pages. Any help would be highly appreciated. P.S. I am thinking about this because OVN got merged with Neutron, and it could be one of the possibilities. **Note**: Please Don't downvote the question because I don't have that much experience with the network could be a stupid question, will remove it if you provide me the info in the comment section. I have found out that installation is possible I am quoting the answer from `https://bugs.launchpad.net/neutron` by `https://launchpad.net/~amotoki` below. "The way to install neutron is simple: to install neutron with pip (from PyPI package or the git repo), prepare a config file for neutron and start the neutron server (in case of OVN mechanism driver). Distro packages and/or various tools like Ansible playbook are just a wrapper for this. The minimum required config to enable noauth (ie without keystone) is to set auth_strategy to noauth in the config file. I don't know the detail instruction step by step to satisfy your need." Now I want to find out detailed instructions for this purpose. is this possible to get the instructions here

[horizon] Support for Django 3.x
by Thomas Goirand 16 Sep '21

16 Sep '21

Hi, It's been a long time that Django 3.x is around, and therefore, it'd be nice if Horizon had some kind of support for it. Indeed, sooner or later, Django 3.x will be uploaded to Debian unstable. That day, I hope Horizon doesn't just break. So, what's the status? Is anyone is at least working on it? Cheers, Thomas Goirand (zigo)

[TripleO][RDO] Plan for TripleO packages in RDO Xena release
by Alfredo Moralejo Alonso 15 Sep '21

15 Sep '21

Hi, With OpenStack Xena GA approaching and TripleO as an independent project, we need to clarify how we will handle it in RDO Xena Release. According to the spec [1]: "TripleO would no longer be able to deploy all versions of OpenStack. One idea that was brough forth in the discussions around this topic thus far, is that we can attempt to address this by designating a range of git tags as compatible with a particular OpenStack stable branch." In practical terms: - When will this list be provided? Can I assume shortly after Xena release (around mid october)? - How will this "list of tags compatible with Xena" be provided by the TripleO project? - How may we describe the maintenance status of TripleO in RDO Xena release? We'd like to include a statement in the release notes. Best regards, Alfredo https://specs.openstack.org/openstack/tripleo-specs/specs/xena/tripleo-inde…

Need some clarification about tenant network in TripleO
by wodel youchi 15 Sep '21

15 Sep '21

Hi, It is a newbie question, but I didn't find a real answer, and I have trouble with my deployment, so some help will be appreciated. In the deployment of TripleO in network isolation, a Tenant network is created, that network (in the examples I have seen) have a VLAN-ID and a subnet. I did the same in my deployment, I created that network. My questions : - Is the Tenant network, mentioned in the deployment process, is it the first tenant network created for the admin tenant? and for new tenant I have to create a new network tenant, despite I am not seeing how I would do that? - Or is it a pipe (a conduit) used to pass the traffic of all the tenants that will be created after? Regards.

[nova] Backporting test refactors to stable/train
by Artom Lifshitz 15 Sep '21

15 Sep '21

Hey Elod and Vlad (and the ML, cc'ed) This is continuing the conversation Elod and I had on IRC. The immediate context is [1], which is a test refactor backport that in turn enables conflict-free backporting of at least two fixes. >From Red Hat's point of view, we will have to care about stable/train for *very* long time, so we'd like to do everything we can to make our lives easier, including backportings things are aren't strictly necessary (like test refactors) in order to greatly facilitate future backports, which tend to be of the "func reproducer test + actual fix" variety. Elod made the excellent point that while this approach does make backports to train much easier to both write and review, it also "postpones" all of the manual conflict resolution work onto anyone doing stable/stein backports. I went and gathered data. I looked at the last 6 months of backports in Gerrit. At the time of this writing, stable/train 72 [2] had and stable/stein had 24 [3]. Out of the latter, Vlad Gusev was the main non-Red Hat contributor. So my proposal is simple: I'm willing to help resolve conflicts in stable/stein backport for folks like Vlad, if it means making backports to stable/train easier. I'm confident that it would still mean an overall reduction in man-hours for backports, even if I become personally on the hook to deal with the fallout of backporting test refactors to stable/train. Cheers!

[tc][neutron] Use Kea insted of Dibbler for IPv6 PD
by Lajos Katona 15 Sep '21

15 Sep '21

Hi, In Neutron we have a bug (see [1]) that states Dibbler is concluded (see [2]), and the developer of Dibbler suggests using Kea (see [3]) instead. Before we start checking technical things first thing is that Kea is MPL2.0 licensed (see [4]) and not sure if we can pull that as dependency to Openstack. Kea is an ISC project so looks safe, but I am not familiar with these legal things. How can we check and be sure? [1] https://bugs.launchpad.net/neutron/+bug/1916428 [2] https://github.com/tomaszmrugalski/dibbler#project-status [3] https://gitlab.isc.org/isc-projects/kea [4] https://www.isc.org/kea/ Thanks in advance Lajos Katona (lajoskatona)

[nova] "Migrating" ComputeNode within ComputeHost / vmwareapi ComputeNode per ESXi
by Wiesel, Fabian 15 Sep '21

15 Sep '21

Hi, I am looking at adding the option for the vmwareapi driver to expose the individual ESXi hosts. A compute-host would represent a cluster in vsphere, and each ESXi-host within a cluster would be a ComputeNode. The main question here is, how to handle a hypervisor initiated change of the compute-node and if the community is open to extending the compute-driver interface for such a use-case. The secondary one is, if there is interest in having the upstream vmwareapi driver getting this functionality. * What are we trying to solve by that? Our users are asking for that feature, because they want to know, if a payload of two VMs runs on the same physical host, as the performance characteristics are quite different. We also gain there from an operational and code perspective: - Nova would become aware of the actual resources per ESXi host instead of the aggregated ones. - Resources could also be more faithfully represented in the resource-tree (e.g., shared storage as an aggregate). - Capabilities, (cpu-flags, architecture,… ), Numa topology, and even small things like up-time can be faithfully reflected on a per-host basis. - The internal scheduling decisions in the driver for ephemeral storage and compute (for live-migration) can be handled by standard placement & nova scheduling. * Why do we need to change the driver interface? Main problem here is that VSphere might migrate a VM between two ESXi-hosts for various reasons. So, the driver would need a way to communicate such a change somehow. But even if we disable all kind of migrations on VMware side, we still need a way to migrate the VMs from the single compute-node for the whole cluster to the compute nodes for each individual ESXi-hosts. * Proposed Driver API Change The Compute-Manager is currently periodically polling the driver with ComputeDriver.get_info(self, instance, use_cache) which returns an InstanceInfo, which is essentially only the power-state. Adding two new optional fields to InstanceInfo could allow the driver to inform the manager about - the current compute-node - the compute-node the VM is migrated to This allows the Compute-Manager to take care of updating the node field and the resource-allocations accordingly. Additionally, we can notify the manager over Instance lifecycle events, allowing for a faster reflection of a compute-node change. The lifecycle events could be - EVENT_LIFECYCLE_COMPUTE_NODE_MIGRATION_STARTED - EVENT_LIFECYCLE_COMPUTE_NODE_MIGRATION_COMPLETED Or one could generalize the current life-migration events to include also such compute-node changes. I am looking forward for your feedback. Cheers, Fabian
