What is the impact of doubling default NumOfPciExpressPorts value?
by ivan.lezhnjov.iv＠gmail.com 09 Nov '23

09 Nov '23

Hi! We've been trying to understand what the effect of increasing NumOfPciExpressPorts might be in terms of system resources consumption and overall system performance of the oVirt Hosts. In this specific scenario, we're running an oVirt deployment with about 100 hosts and thousands of VMs. oVirt allocates 16 PCIe ports by default (or is it QEMU defaults?) and we would like to increase that number to about 30. However, only very few VMs are actually gonna use those extra PCIe ports in terms of having additional devices (like NICs). So, basically, there will be a lot of VMs that have about twice as many PCIe ports available to them than now but not really using them (as in having actual additional devices created and associated with the VMs). How is that going to impact physical servers that are running the VMs? Any potential problems for the VMs themselves? Ivan

Unable to start HostedEngine

After a failed attempt at migrating our HostedEngine to a new iSCSI storage domain, we're unable to restart the original HostedEngine. Please see below for some details, and let me know what more information I can provide. "Lnxvirt07" was the Host used to attempt the migration. Any help would be greatly appreciated.

Hosted-engine restore failing when migrating to new storage domain
by Devin A. Bougie 08 Nov '23

08 Nov '23

Hello, We have a functioning oVirt 4.5.4 cluster running on fully-updated EL9.2 hosts. We are trying to migrate the self-hosted engine to a new iSCSI storage domain using the existing hosts, following the documented procedure: - set the cluster into global maintenance mode - backup the engine using "engine-backup --scope=all --mode=backup --file=backup.bck --log=backuplog.log" - shutdown the engine - restore the engine using "hosted-engine --deploy --4 --restore-from-file=backup.bck" This almost works, but fails with the attached log file. Any help or suggestions would be greatly appreciated, including alternate procedures for migrating a self-hosted engine from one domain to another. Many thanks, Devin

Call for participation: Virtualization and Cloud infrastructure Room at FOSDEM 2024
by Piotr Kliczewski 08 Nov '23

08 Nov '23

We are excited to announce that the call for proposals is now open for the Virtualization and Cloud infrastructure devroom at the upcoming FOSDEM 2024, to be hosted on February 3rd 2024. This devroom is a collaborative effort, and is organized by dedicated folks from projects such as OpenStack, Xen Project, KubeVirt, QEMU, KVM, and Foreman. We would like to invite all those who are involved in these fields to submit your proposals by December 8th, 2023. About the Devroom The Virtualization & IaaS devroom will feature session topics such as open source hypervisors or virtual machine managers such as Xen Project, KVM, bhyve and VirtualBox as well as Infrastructure-as-a-Service projects such as KubeVirt, Apache CloudStack, OpenStack, QEMU and OpenNebula. This devroom will host presentations that focus on topics of shared interest, such as KVM; libvirt; shared storage; virtualized networking; cloud security; clustering and high availability; interfacing with multiple hypervisors; hyperconverged deployments; and scaling across hundreds or thousands of servers. Presentations in this devroom will be aimed at developers working on these platforms who are looking to collaborate and improve shared infrastructure or solve common problems. We seek topics that encourage dialog between projects and continued work post-FOSDEM. Important Dates Submission deadline: 8th December 2023 Acceptance notifications: 10th December 2023 Final schedule announcement: 15th December 2023 Devroom: 3rd February 2024 Submit Your Proposal All submissions must be made via the Pretalx event planning site[1]. It is a new submission system so you will need to create an account. If you submitted proposals for FOSDEM in previous years, you won’t be able to use your existing account. During submission please make sure to select Virtualization and Cloud infrastructure from the Track list. Please fill out all the required fields, and provide a meaningful abstract and description of your proposed session. Submission Guidelines We expect more proposals than we can possibly accept, so it is vitally important that you submit your proposal on or before the deadline. Late submissions are unlikely to be considered. All presentation slots are 30 minutes, with 20 minutes planned for presentations, and 10 minutes for Q&A. All presentations will be recorded and made available under Creative Commons licenses. In the Submission notes field, please indicate that you agree that your presentation will be licensed under the CC-By-SA-4.0 or CC-By-4.0 license and that you agree to have your presentation recorded. For example: "If my presentation is accepted for FOSDEM, I hereby agree to license all recordings, slides, and other associated materials under the Creative Commons Attribution Share-Alike 4.0 International License. Sincerely, <NAME>." In the Submission notes field, please also confirm that if your talk is accepted, you will be able to attend FOSDEM and deliver your presentation. We will not consider proposals from prospective speakers who are unsure whether they will be able to secure funds for travel and lodging to attend FOSDEM. (Sadly, we are not able to offer travel funding for prospective speakers.) Code of Conduct Following the release of the updated code of conduct for FOSDEM, we'd like to remind all speakers and attendees that all of the presentations and discussions in our devroom are held under the guidelines set in the CoC and we expect attendees, speakers, and volunteers to follow the CoC at all times. If you submit a proposal and it is accepted, you will be required to confirm that you accept the FOSDEM CoC. If you have any questions about the CoC or wish to have one of the devroom organizers review your presentation slides or any other content for CoC compliance, please email us and we will do our best to assist you. Questions? If you have any questions about this devroom, please send your questions to our devroom mailing list. You can also subscribe to the list to receive updates about important dates, session announcements, and to connect with other attendees. See you all at FOSDEM!

Moving hosted-engine to a new cluster
by Ling Ho 08 Nov '23

08 Nov '23

Hello, I set up some new hypervisors recently, created a new cluster using the newer CPU, and migrated all my VMs by changing the cluster and restarting them. Now I have the hosted engine left running in my old cluster. I could not find any recent documentation or discussion on the net. What's the proper way to migrate the hosted engine? I am on oVirt 4.5.4. Thanks, ... ling

Cannot "Change CD" from VM portal with standard user
by Gianluca Amato 07 Nov '23

07 Nov '23

Hello, I am trying to attach a CD to a virtual machine from the VM Portal as a standard user. When I click on the box for choosing the ISO image, I only get "[Empty]". However, when I access the VM portal as an admin, I correctly see the list of ISO images. I suspect it is a problem of permission: I have assigned to the unprivileged user the UserRole permission both for the VM and the ISO disk images. Am I doing something wrong ? Do I need to assign different roles ? Thanks, --gianluca

How to start QA and testing work in the oVirt project?
by song_chao＠massclouds.com 06 Nov '23

06 Nov '23

Hello everyone, I am a testing and development engineer who has been working for 10 years. I want to learn and participate in Ovirt's testing work, and make my own contribution. Through learning and understanding, I believe that in the near future, I can also make some contributions to the ovirt community. Currently, I would like some information about QA and testing processes and methods. Can anyone provide me with it? Thank you.

Missing OVF_STORE disks. Impact and how to recover them?
by ivan.lezhnjov.iv＠gmail.com 06 Nov '23

06 Nov '23

Hi! We have a Local Storage SD (Storage Domain) that is missing both OVF_STORE disks. Clearly this SD is strictly speaking broken but the oVirt Host where this SD is configured and VMs that run on that Host seem to be doing fine. No major problems except for the fact that oVirt Events logs are filled with "VDSM command SetVolumeDescriptionVDS failed: Image path does not exist or cannot be accessed/created" error (and a couple others associated with this one) that is generated every 1 hour. Is this SD in a critical state? Are we risking losing data or anything like that? What is the impact of deleting OVF_STORE disks from an SD? And most importantly is there a way to recover/recreate these OVF_STORE disks?
