Cannot logon cockpit for Ovirt 4.5.5
by Ethan Provensen 27 Jan '26

27 Jan '26

I am new to all of this. I recently downloaded the latest ISO, ovirt-node-ng-installer-latest-el9.iso, and I am trying to follow the directions. When I try to access cockpit on another PC with a GUI desktop and try to logon cockpit with root and the password I set for root when I created the server, it says wrong "Wrong user name or password". What user name should I be using to logon cockpit? All the the information I found, I am supposed to use root with the password I gave root when I created the oVirt server. What am I doing wrong?

oVirt Administration Portal will not load after upgrade to 4.5.7
by scottwilkins＠cicsnc.org 26 Jan '26

26 Jan '26

I'm running oVirt in standalone on a Centos Stream 9 box. The VM Portal will load fine, but the Admin Portal fails with a 500 error. When I dig down in the server log, the error message is: Caused by: java.lang.IllegalArgumentException: MigrationPolicies has no value for version: 4.8 When I run engine-config -g MigrationPolicies I get results for version 4.2 up to 4.7, but nothing for 4.8. Is this something I need to manually add? One other piece of confusing info is that the console still lists the version as 4.5.6-1.el9. I didn't see any errors during either the yum update or the engine-setup processes, but I may have missed something. Any help you all can give me would be great.

CentOS Repo Disable for oVirt 4.5.7

by Jean-Louis Dupond 20 Jan '26

20 Jan '26

*oVirt 4.5.7 is now generally available* The oVirt Project is pleased to announce the availability of the 4.5.7 release as of January 13 2026. oVirt is a free open-source distributed virtualization solution, designed to manage your entire enterprise infrastructure. oVirt uses the trusted KVM hypervisor and is built upon several other community projects, including libvirt, Gluster, PatternFly, and Ansible. This release is now available on x86_64 architecture for: oVirt Node NG (based on CentOS Stream 9) CentOS Stream 9 CentOS Stream 10 RHEL 9 and derivatives RHEL 10 and derivatives To everyone using the oVirt Node NG we urge you to switch over to another way of using the product for ensured stability and security due to the way of how that product is structured. To find out how to interact with oVirt developers and users and ask questions, visit our community page. All issues or bugs should be reported via oVirt GitHub. If you’d like to try oVirt as quickly as possible, follow the instructions on the Download page. For complete installation, administration, and usage instructions, see the oVirt Documentation. For a general overview of oVirt, read the About oVirt page. To learn about features introduced before 4.5.7, see the release notes for previous versions. IMPORTANT If you are going to install on RHEL or derivatives please follow Installing on RHEL first. NOTE It is important that for installs on RHEL 10 and derivates that version 10.0-4 (or newer) of centos-release-ovirt45 is used. What’s New in 4.5.7? New releases in 4.5.7 Contributors New cpu’s What’s New in 4.5.7? CentOS 10 and AlmaLinux 10 support. Fixed CVE-2024-7259 Introduced new CPU’s Bumped external dependencies. Implemented new way of deploying to maven central. All Java code is now built on Java 21 and compatible with Java 11. Reconnect faster to host after reboot, instead of static 10 minutes adapted to connect when host is back online. On boot of VM have a spare of NumOfPciExpressPorts PCIe ports available instead of a fixed number. Add the optional attach_wgt flag to the vm start endpoint. This will auto attach the virtio-win iso to the vm. Ability to add tags to templates via UI in the administration panel. Add operating system description to host api object. Added option for user to decide preference of vnc console invocation. Added Windows 2025 and RHEL 10 to OS list. Improve isLiveDelete check on VM. Dropped deprecated packages. Dropped Ceph, Cinderlib and collectd in Centos 10 due to not available. Added new DC/Cluster level (4.8). Cluster level 4.8 now uses pc-q35-rhel9.6.0 machine type and enables discard-no-unref by default. Added ability to alter video device through API. Set audio value to ich9 starting from rhel7 on Q35. When a VDS network error occurs during VM start, set the VM status to “Unknown” instead of letting it fall through to “Down”. This to prevent duplicate VM deployments. Ability to update QoS on running VM’s when a QoS profile has been modified or when QoS was changed on a vNIC profile Many more changes were implemented in the newest releases of the oVirt packages and can be read about in detail down below.

oVirt 4.5.7 upgrade guide for RHEL8 systems
by Kapetanakis Giannis 20 Jan '26

20 Jan '26

oVirt 4.5.7 release is definitely good news and kudos to the devs behind this release. Can we have a documentation ideally on https://www.ovirt.org/documentation/upgrade_guide/ or at least in the mailing list for the upgrade path from RHEL8 (and derivatives) and 4.5.6 to 4.5.7 on newer OS? I see on release notes that only RHEL9+ is supported for both engine and hosts. Our systems, both standalone engine as well as hosts are all on Rocky 8. Will a backup of engine, install of 4.5.7 on new OS and restore from backup will be able to see and manage the non-upgraded RHEL8 hosts? Maybe upgrade the hosts first and the engine later? What is the recommended way of making the upgrade? On more question: RHEL10 does not see v2 hosts. Alma does support them. Are there v2 binaries released for RHEL10 systems (engine and hosts) or should we stick to RHEL9. Thanks, Giannis

Deploy process frezzes with "Wait for the host to be up"
by Leandro Pereira 19 Jan '26

19 Jan '26

Hello everyone I'm installing ovirt 4.5 on a homelab VMWare Workstation (which I did several times weeks ago). Not so much that I'm going through technical problems. The deploy engine works in a stage called '[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Wait for the host to be up]'. I couldn't find any error messages in both the Host logs and the Engine. Try different ways to automatically create the ovirtmgmt network, as you previously created it. The fact is that at this stage the engine is still not connected to the ovirtmgmt network, and from this point the depoloy does not pass through the host cannot communicate with the Engine with the FQDN informed.

oVirt thick client Python+QT6 - any interest?
by John Boero 17 Jan '26

17 Jan '26

Hi I've been a longtime fan of oVirt since my Red Hat days. I was just playing around with vibe coding a thick client in Python + QT6 to give oVirt the app I think it always deserved. Results are early but pretty slick actually. Is anybody interested in pulling this into the GH org and developing further? An early beta after about 2 hours of playing can be found here: https://github.com/jboero/ovirt_client John Boero

Offline installation - is is possible?
by postecom＠gmail.com 15 Jan '26

15 Jan '26

I have been looking at oVirt for a while. My current virtualization is an older version of RHV. With RHV, I could have my hypervisors completely isolated from the internet and all updates come through Red Hat's Satellite. Is is possible to add the installation repos as a product in Satellite? It is very important that the hypervisors not have access to the Internet, but all the documentation and installation info that I can find wants the hypervisors to use the COPR plugin and have direct access to centos stream. Thank you
