[Nova][Kolla][VDI] Introducing Kerbside delivery of VDI console sessions
by Michael Still 06 Apr '24

06 Apr '24

Hi all, for the longest time I've thought it was super cool that you could do something like this with Google Cloud: `gcloud compute ssh ...instance...` This causes a SSH session to run in your terminal that transparently proxies you through to the instance. It even orchestrates SSH authentication using a CA, but that's a story for another day. Aptira had a similar business need, but with more of a focus on virtual desktop environments, and therefore kindly supported my development work on a SPICE protocol native proxy I've called Kerbside [1][2]. The proxy works by scraping various clouds' REST APIs for "VDI capable" instances, and then making those available via short lived session tokens. The intention is that a service like Horizon or Skyline could request a session token for a specific instance, which is returned to the user as a `.vv` style virt-viewer configuration file. The user then opens the configuration file and a connection to the console on the relevant hypervisor is provided by Kerbside. Kerbside can do more than that of course. It has a simple management UI and API, which allows for things like forced termination of a console session once setup, logging and audit history, TLS support, and so forth. Kerbside and all associated work is licensed under the Apache 2 license, just the same as OpenStack, and positions clouds to offer Citrix-like virtual desktops to their users in a seamless manner. Why a SPICE proxy? As best as I can tell, SPICE still provides the richest virtual desktop experience. It supports high resolution desktops, multi-screen desktops, USB device passthrough, sound, multiple user connections to a single console, and so forth. Why not the current HTML5 transcoding proxy as used by Horizon? Unfortunately, the current HTML5 SPICE client does not support most of the features listed in the previous paragraph. While originally intended for the purposes of my personal Shaken Fist project, Kerbside now supports OpenStack and oVirt as well. In the case of OpenStack, this required a number of patches to OpenStack projects to get working [3]. Specifically I'd like to propose a new Nova API microversion to support a new "spice-direct" console type. I intend to work through the Nova specs process for the Nova related changes, and have created a blueprint [4] to track that work. I am working on a draft spec at the moment [5], but do not see the required changes to Nova as particularly invasive. You can of course assess that yourself by reading the proof of concept patches in the kerbside-patches repository. This raises some questions for me. Specifically: - is this functionality interesting to others? Or is it just me? - what is the process of proposing changes like this for Kolla and Kolla-Ansible? I chose to build my proof of concept on that platform, so I also have a number of aligned deployment patches there. - I've been out of the OpenStack universe for a while now. Is it too late to propose this work for Dalmation? Thanks, Michael 1: https://github.com/shakenfist/kerbside and https://github.com/shakenfist/kerbside-client 2: Why Kerbside? Well because Horizon and Skyline are distant things, whereas I wanted to create something closer... Like Kerbside pickup from a shop. 3: https://github.com/shakenfist/kerbside-patches 4: https://blueprints.launchpad.net/nova/+spec/libvirt-spice-direct-consoles 5: https://github.com/shakenfist/kerbside-patches/blob/develop/nova-specs/patc…

As we've done in PTGs past, we're getting devs and ops together to talk about Swift: what's working, what isn't, and what would be most helpful to improve. We're meeting in the dalmation swift meetpad room ( https://meetpad.opendev.org/swift-ptg-dalmatian) on Wednesday at 13:00UTC -- if you run a Swift cluster, we hope to see you there! Even if you can't make it, we'd appreciate it if you can offer some feedback on the etherpad ( https://etherpad.opendev.org/p/swift-dalmation-ops-feedback) This has always been a highlight at every PTG for us swift devs. Have your say and help make Swift even better!

[kolla] [mariadb] Backups failing if they take over an hour
by Chris DiLorenzo 05 Apr '24

05 Apr '24

Were using the mariadb_backup command of kolla-ansible to backup the database. We're doing daily, full backups. It's been working fine until recently. Now we are getting this error: 2024-04-03 21:16:33 0 [Note] InnoDB: Read redo log up to LSN=317647271424 2024-04-03 21:16:48 0 [Note] InnoDB: Read redo log up to LSN=317647424512 2024-04-03 21:17:03 0 [Note] InnoDB: Read redo log up to LSN=317647586304 2024-04-03 21:17:18 0 [Note] InnoDB: Read redo log up to LSN=317647733248 [01] 2024-04-03 21:17:23 ...done [00] FATAL ERROR: 2024-04-03 21:17:23 failed to execute query SET SESSION lock_wait_timeout=31536000: Server has gone away It started as soon as the DB backup took more than 1 hour. In our other environments where the backup is < 1hr, it works fine. There are no errors in the logs when this happens, other then the above output from mariabackup Any suggestions? Thanks, Chris

by keshav bareja 04 Apr '24

04 Apr '24

Hi Team I am planning to update my environment from the current ussuri minor version to the latest minor version available for the Ussuri. I found the procedure below. https://docs.openstack.org/openstack-ansible/ussuri/admin/upgrades/minor-up… I have some queries on this: 1. How to find the current minor release version of the Ussuri deployed on my environment? Is there any command or way that can help? 2. What is the latest minor version available for Ussuri? In the Ussuri release notes page I could see 2.10, can someone please confirm if 2.10 is the latest version? 3. Also I need to know the bug fixes between my current release to the latest minor ussuri release. 4. Can someone confirm what all pre-requisite I need to take care of before going with the update. 5. Anyone having experience with such minor updates , Please share precaution and recommendations, Ussuri Series Release Notes <https://docs.openstack.org/releasenotes/openstack-ansible/victoria.html> <https://docs.openstack.org/releasenotes/openstack-ansible/train.html> <https://bugs.launchpad.net/openstack-ansible/+filebug?field.title=Ussuri%20…> 21.2.10 <https://docs.openstack.org/releasenotes/openstack-ansible/ussuri.html#relno…>Security Issues <https://docs.openstack.org/releasenotes/openstack-ansible/ussuri.html#secur…> - This release eliminates following security issues: - OSSA-2021-005: https://security.openstack.org/ossa/OSSA-2021-005.html - OSSA-2021-006: https://security.openstack.org/ossa/OSSA-2021-006.html
