[FOSDEM][CFP] Virtualization & IaaS Devroom
by Piotr Kliczewski 10 Nov '22

10 Nov '22

We are excited to announce that the call for proposals is now open for the Virtualization & IaaS devroom at the upcoming FOSDEM 2023, to be hosted on February 4th 2023. 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 10th, 2022. 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: 10th December 2022 Acceptance notifications: 15th December 2022 Final schedule announcement: 20th December 2022 Devroom: First half of 4th February 2023 Submit Your Proposal All submissions must be made via the Pentabarf event planning site[1]. If you have not used Pentabarf before, you will need to create an account. If you submitted proposals for FOSDEM in previous years, you can use your existing account. After creating the account, select Create Event to start the submission process. Make sure to select Virtualization and IaaS devroom 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.) Submission Guidelines Mentored presentations will have 25-minute slots, where 20 minutes will include the presentation and 5 minutes will be reserved for questions. The number of newcomer session slots is limited, so we will probably not be able to accept all applications. You must submit your talk and abstract to apply for the mentoring program, our mentors are volunteering their time and will happily provide feedback but won't write your presentation for you! If you are experiencing problems with Pentabarf, the proposal submission interface, or have other questions, you can email our devroom mailing list[2] and we will try to help you. How to Apply In addition to agreeing to video recording and confirming that you can attend FOSDEM in case your session is accepted, please write "speaker mentoring program application" in the "Submission notes" field, and list any prior speaking experience or other relevant information for your application. 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. Call for Volunteers We are also looking for volunteers to help run the devroom. We need assistance watching time for the speakers, and helping with video for the devroom. Please contact devroom mailing list [2] for more information. 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!

Hello, I'm planning to upgrade ovirt engine to 4.5, but I need now to install additionnal hosts. Is it safe to directly install my new hosts with ovirt-node 4.5 and attach them to 4.4 engine?

Blog Post - Using Ceph Only Storage For oVirt Datacenter by Sandro Bonazzola – Wednesday 14 July 2021
by Matthew J Black 10 Nov '22

10 Nov '22

Hi All, In the above mentioned blog post (https://blogs.ovirt.org/2021/07/using-ceph-only-storage-for-ovirt-datacente…) in mentions the line: "Follow oVirt documentation for setting up Cinderlib" with a link to this URL: https://ovirt.org/documentation/installing_ovirt_as_a_self-hosted_engine_us… This link is broken/obsolete/no longer available, so my question(s) is/are: Where can I obtain this information? Is there a new URL? Are these instructions no-longer required with the new oVirt v4.5.X? Can someone who has these instructions post/email them, please? Thanks in advance Dulux-Oz

Hello community, since yesterday I try to update my cluster, but when I was trying it through GUI it never finished and when I try it manually I got: [MIRROR] ovirt-node-ng-image-update-4.5.3.2-1.el8.noarch.rpm: Downloading successful, but checksum doesn't match. Calculated: 365a886b0a2784fa5304d7581970e56a312ab0789c4a97fd329bbd7313da736c(sha256) Expected: 04979b883581b7ccb51ec063329b87a92bc5ea4405a161384cfdea68215e5306(sha256) and it starts again the download process. Before I also run: dnf clean all Can it be, that something with the mirrors are wrong? Best Regard Jonathan

hi I've try to install new hosted-engine version but deploy process finish with an error after vm start on shared storage (FC disks from SAN storage). [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Check engine VM health] this cuz Jboos web page not working "Service Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later." I open console to VM engine and... disk dm-6 and dm-3 was corrupted - LOL - must fix by xfs_repair. But after restart hosted-engne.service wont start. ● ovirt-engine.service - oVirt Engine Loaded: loaded (/usr/lib/systemd/system/ovirt-engine.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Mon 2022-10-31 15:35:30 CET; 4min 11s ago Process: 1469 ExecStart=/usr/share/ovirt-engine/services/ovirt-engine/ovirt-engine.py --redirect-output --systemd=notify $EXTRA_ARGS start (code=exited, status=1/FAILURE) Main PID: 1469 (code=exited, status=1/FAILURE) Oct 31 15:35:23 ovirt systemd[1]: Starting oVirt Engine...

How to reset admin@ovirt in keycloak
by Sven Jansen 07 Nov '22

07 Nov '22

Hello, after setting up a new oVirt Cluster with buildin keycloak i have issues login in as admin@ovirt, looks like i saved the wrong password in my password manager, now i have issues finding a way to reset the password of this user to do administration in the keycloak admin console, i tried changing the password with: /usr/share/ovirt-engine-keycloak/bin/add-user-keycloak.sh and /usr/share/ovirt-engine-wildfly/bin/add-user-keycloak.sh. Both without success, i found i can create a new "keycloak-add-user.json" with the second command and i can copy it over to the right place where the old file was, after rebooting the hosted engine this has no effect. Is there a known way to reset admin@ovirt with the internal keycloak? i cant find anything in the docs.

infrastructure boostrap. (i.e engine start / autostart).
by duparchy＠esrf.fr 07 Nov '22

07 Nov '22

Hi, We decided to run the oVirt engine (Oracle flavor) outside the infrastructure. (Medium infrastructure, 10 Hosts, iSCSI storage arrays) We created a second, smaller infrastructure (Single host, local storage) for management (engine) and monitoring (nagios, Dell storage manager etc..) . . This secondary infrastructure's engine runs in the first infrastructure. So, If you picture it, we're facing a "bootstrap" cross-dependency problem where each engine need the other one to start. This is actually a design we had when we were using Xen (Oracle's). Xen provides the "xen create" command to start a VM, even w/o a manager. Bootstrap problem solved. We're moving to oVirt and I understand that oVirt does not support out-of-the-box starting a VM w/o the engine. I've found a workaround that seems to work and would like your advice : - keep a dump of XML of the engine VM # virsh -r dumpxml prodEngine > prodEngine.xml - When necessary use virsh to start the engine # virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf create prodEngine.xml The only visible problem is a warning at the VM that was started manually saying "Newer configuration for next run". A restart clears the warning and there's does not seem to be consequences with the VM that had been started from a dump xml. Note : I understand that there is the "self-hosted" engine architecture that solves that "bootstrap" problem. We're no into that for now. We had bad experience with that design in the past.

Locking down management network
by David White 05 Nov '22

05 Nov '22

I just discovered that my default management network has the "VM Network" checkbox toggled (on the page where you navigate to Network -> Networks and select the management network). There are no virtual machines associated with the management network. Is it safe to simply edit the management network and uncheck the "VM Network" box? Will anything break (even temporarily) if I do this? Sent with Proton Mail secure email.

Virtual Machine Pools
by Christopher Law 04 Nov '22

04 Nov '22

Hopefully, someone can clarify this a bit for me... From the redhat instructions... "In principle, virtual machines in a pool are started when taken by a user, and shut down when the user is finished. However, virtual machine pools can also contain pre-started virtual machines. Pre-started virtual machines are kept in an up state, and remain idle until they are taken by a user. This allows users to start using such virtual machines immediately, but these virtual machines will consume system resources even while not in use due to being idle." How do users request "take" virtual machines from the pool? For example with a windows machine where we want them to remote desktop into it using RDP? Or does this have to happen through some other portal? Do we have to give users access to the VM Portal? Cheers, Chris.
