Offline installation - is is possible?
by postecom＠gmail.com 08 Jan '26

08 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

install el10 host with ovirt45-testing
by Jiří Sléžka 02 Jan '26

02 Jan '26

Hi, I am testing host installation from ovirt45-testing repo. I choose Alma Linux 10 for it as it still support Spice. Engine runs also 4.5.7 but on Rocky Linux 9. Other hosts are Rocky Linux 8. First small glitch is that after yum install centos-release-ovirt45-testing the repo centos-ovirt45-testing is disabled by default. I did not mention it and try to create new host witch failed early in Install stage (playbook can't find ovirt packages). I know it is not typical problem but in this case I ended up with host stucked in Install stage and cannot switch it to maintenance and/or remove it. I had to do it directly in db. Second try was without problems but after I set-up network I ended in Non operational mode because "Host does not comply with the cluster emulated machine. The cluster emulated machine is pc-i440fx-rhel7.6.0;pc-q35-rhel8.6.0 and the host emulated machines are pc-q35-rhel9.6.0,pc-q35-rhel9.4.0,q35,pc-q35-rhel9.2.0,pc-q35-rhel9.0.0,pc-q35-rhel10.0.0,pc,pc-i440fx-rhel10.0.0." As I read list archives I could try "Reset Emulated Machine" in Cluster menu. Current emulated machine type is pc-q35-rhel8.6.0. One odd thing is that "Clusters hosts must be down in order to perform this action." which leads me to question whether it is safe or possible in my current mix of el8 and el10 hosts. Cheers, Jiri

Fantastic! ________________________________ From: Jean-Louis Dupond via Announce <announce(a)ovirt.org> Sent: Thursday, December 18, 2025 7:24 PM To: announce(a)ovirt.org <announce(a)ovirt.org> Cc: Jean-Louis Dupond <jean-louis(a)dupond.be> Subject: [ovirt-announce]oVirt 4.5.7 - Testing Hi, It's been some month since previous announcement. But the moment we've been waiting for is here! I am happy to announce that oVirt 4.5.7 is finally build and ready for testing in our testing repository! You can install the version by installing the `centos-release-ovirt45-testing` package and activate the testing repository by issueing `dnf config-manager --set-enabled centos-ovirt45-testing` This should work on CentOS 9 and 10, but also on AlmaLinux 9 and 10. If there are questions, feel free to reach out on our Matrix channel: https://matrix.to/#/#ovirt:ovirt.tech Currently we are preparing the release notes, and when no major bugs pop-up, the release will happen soon! Changes? Some important/good to know changes since 4.5.6: - Support for new Intel and AMD CPU's - Fixed 2 cases where corruption could occur - CentOS 10 and AlmaLinux 10 support! - PCI slot improvements - New machine type - Cluster version 4.8 - All Java code build on Java21 and compatible with Java11+ - And much more! Thanks Jean-Louis

It doesn't matter if it's a fresh install or import. I go to ui and edit vm and change to one of the default size templates, usually large, it boots with no nic and I can add a nic once it's booted and restart it, then it gets an IP and is fine unless you shut it down. In that case, you have to go through setting size and adding nic after vm boot. Any help would be appreciated. Thanks in advance/

import VM from Qemu-KVM
by Enrico Becchetti 15 Dec '25

15 Dec '25

Dear all, I've a question about import VM from an external hypervisor. My oVirt is 4.3: N. 3 Dell R7525 servers with CentOS 7 SAN BROCADE and HPE MSA P 2050 (domain: DATA_FC_P2050) 10Gbps network, NFS Server (domain: NFS) I need to import a virtual machine running on a Qemu-KVM server into ovirt. The file type is qcow2, about 100GB. I tried with GUI "Storage->Disk->Upload" but I've got an error: "Connection to ovirt-imageio-proxy service has failed. Make sure the service is installed, configured, and the ovirt-engine certificate is registered as a valid CA in the browser." Can you tell me the correct sequence for this operation and for importing and running the virtual machine in ovirt? Thanks a lot Best Regards Enrico -- __________________________________________________________________________ Enrico Becchetti Servizio di Calcolo e Reti Istituto Nazionale di Fisica Nucleare - Sezione di Perugia Via Pascoli,c/o Dipartimento di Fisica 06123 Perugia (ITALY) Phone:+39 075 5852777 Mobile: +39 075 9696225 FAX: +39 075 5847296 Microsoft Teams: becchett(a)infn.it Mail: Enrico.Becchetti<at>pg.infn.it Pagina web personale: https://www.pg.infn.it/home/enrico-becchetti _________________________________________________________________________

swtpm
by Winfried de Heiden 12 Dec '25

12 Dec '25

Hi all, I'm currently running oVirt 4.5.7 and added a (virtual) tpm2 device to one of my VM's for the sake of experimenting with tpm2 and it's commands. Experimenting means breaking stuff :) and I need to reset the tpm device on a regular base. Using kvm and virsh; this is fairly easy: "rm -rf /var/lib/libvirt/swtpm/$(virsh domuuid tpm2)/tpm2" will do to start with a new virtual tpm device. On oVirt, how can I reset (destroy, create new one) the virtual tpm device? Thanks! Winfried

Installing oVirt 4.5 on RHEL 9 (Offline / NIST 800-53 Compliance)
by Rockwell, Jenn - US 11 Dec '25

11 Dec '25

Hi all, I’m working on setting up production oVirt 4.5 with a self-hosted engine on RHEL 9 in an offline, NIST 800-53 environment. The server does not have internet access, but I can download repositories and packages separately and hand transfer them over. I’ve looked through the available documentation, but aside from https://www.ovirt.org/download/install_on_rhel.html, I haven’t found details on which additional repositories (RHEL, oVirt, dependencies, etc.) are required for a full installation. I’m looking for guidance on the best approach for this type of setup. Ideally, whether there’s a simpler or supported method to get a self-hosted engine running in an offline environment without having to mirror all repositories manually. Thanks in advance for any advice or pointers.

Need advice with 3 servers and 1 SAN
by provensen＠aol.com 10 Dec '25

10 Dec '25

I am new to oVirt, and I am trying to find the right solution for my LAN. On an air-gapped network, I have 3 Dell PowerEdge servers running Alma Linux 9 and 1 IBM SAN. I have 3 iSCSI connections from the IBM SAN to the 3 Dell servers. I am looking to install oVirt as 3 Enterprise Linux hosts on the 3 Dell servers. I need the 3 Enterprise Linux hosts to have shared storage, so all 3 hosts can access all of the virtual machines. I need the storage to have high availability, so if 1 host goes down the virtual machines can run on the other hosts. Which kind of storage do I use for this? NFS, iSCSI, cluster...etc? Also, do I connect the IBM SAN to only 1 host, and share that IBM SAN storage with the other 2 hosts, or would I create 3 separate iSCSI connections to each host? I would really appreciate any assistance from anyone. Thank you.

Unable to upload or download iso via admin portal
by Igor Filipovic 09 Dec '25

Hi, I'm having a trouble on fresh 4.4.10.7 installation (on oracle linux), I'm not able to upload or download any file using storage domain upload image function. I've imported CA certificate and have tried on several browsers (firefow, chrome,edge), on different computers (and browsers are green - claiming that I'm securely connected), but I'm always getting error regarding CA certificate when I test connection, or when I try to upload ISO image. I've tried to upload ISO image via cli commands (upload_disk.py), and that scenario was successful, however this method It is not very convenient for my co-workers. I have 5 physical hosts, one is dedicated to run ovirt-engine, and other 4 are kvm hypervisors. When I try to upload ISO this is what engine.log logs: 2023-04-08 11:00:28,339+02 INFO [org.ovirt.engine.core.bll.storage.disk.image.TransferImageStatusCommand] (default task-2) [f6b62add-0a0c-45ee-a985-a76171843382] Running command: TransferImageStatusCommand internal: false.
