Offline installation - is is possible?
by postecom＠gmail.com 24 Dec '25

24 Dec '25

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

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/

Need advice with 3 servers and 1 SAN
by provensen＠aol.com 11 Dec '25

11 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

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.

Good solution. We are testing Vinchin Backup & Recovery and it works perfect. I think it could be a good alternative to Veeam.

Installing oVirt on Oracle Linux 9
by Igor Filipovic 22 Oct '25

22 Oct '25

Hi, In case anyone's interested: Today I successfully deployed a new oVirt 4.5.7 on Oracle Linux 9.6 hosts. The bottom line: deployment went fine on a minimal OL9.6 install. In addition to the ovirt/ovirt-master-snapshot repository, you must also enable the ol9_codeready_builder repository — it's required to install libvirt-lock-sanlock. After that SHE installation went smoothly. OS Version: RHEL - 9.6 - 1.0.9.el9 OS Description: Oracle Linux Server 9.6 Kernel Version: 6.12.0 - 104.43.4.2.el9uek.x86_64 KVM Version: 9.1.0 - 15.el9_6.9 LIBVIRT Version: libvirt-10.10.0-7.7.0.1.el9_6 VDSM Version: vdsm-4.50.6-202510211310.git33e8c2c63.el9

Hosted engine deployment failing on step Check OVF_STORE volume status

Hi, I have tried several different physical hosts and several different OS releases (Alma 9.6, Rocky 9.6, CentOS 9 stream) to deploy hosted engine.

Migrating hosted engine to new storage
by Seann G. Clark 20 Oct '25

20 Oct '25

All, I have been working on this issue for a few weeks now. I am moving off old fiber-channel storage to new iSCSI, and the last device to move is the hosted-engine. From everything I have read, the standard procedure/mentality on migrating this should look as follows for 4.5, which is the version I am on: 1.) Backup existing hosted engine 2.) Set cluster into global maintenance 3.) Re-install hosted engine from backup taken in step 1 (this step fails, never gets to the point to select a new storage backend. Can't seem to find anything on why it fails reading the logs) 4.) Select new storage backend 5.) Decommission/cleanup legacy storage I have run into a few issues, mostly self-inflicted that have caused issues with upgrades, specifically using custom/external certificates for the management console instead of the default out of the box certificate set from initial install. This was done by the book, so to speak using the well documented approach on it. That is the only real customization that was done with the solution, though. This also caused issues with keycloak install/setup. As part of my continued troubleshooting with this, is there a way to revert the Apache certificates back to the internally setup/initially deployed SSL keys after the original ones have long expired? If anyone has any idea's that might help, I am open to that as well. Regards, Seann

vm only starts with a built in indtance template

I have a 3 host ovirt hosts 4.5 and gluster 1o. The firewall is confiirured and SELinux enforcing. I have the same issue with selinux and firewall disabled. I cannot start a vm unless I use the preconfigured instance templates. You cannot add a network card or it fails. I honestly at a loss. Otherwise it works fine except for the scheduling does not balance with 12 vms. I am sure yoy are also aware sso is noit working and seems to be widespread. It looks like you can get a working one somewhere with out a red hat entitlement. It says it cannot fine remote executable in /usr/sbin. I can't find it any where and it comes with the cockpit-ws package whick is installed and double checked to make syre dependancies were covered. Any help or insight woiuld be appreciated Thanks for your time. Eric

Installing oVirt on RHEL vs CentOS Stream, Alma or Rocky Linux
by Richard W.M. Jones 06 Oct '25

06 Oct '25

I'm still struggling to get oVirt installed. It absolutely will not install on RHEL 8, the documentation here is flat out wrong: https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manage… javapackages-tools is not a module that exists in RHEL 8. Apparently it's a CentOS PowerTools module. Since original CentOS no longer really exists either, does anyone have any opinions or experience with installing oVirt on any of: - CentOS Stream 8 - Alma Linux 8.5 - Rocky Linux Alma in particular looks like a straight replacement for old CentOS.

Continuing will configure this host for serving as hypervisor and will create a local VM with a running engine.

GlusterFS & NFS Storage Performance in OLVM/Ovirt – Tuning Advice Needed
by Gunasekhar Kothapalli 02 Oct '25

02 Oct '25

Hi all, I’m benchmarking storage performance on OLVM using fio across several scenarios (local brick, GlusterFS, NFS, both on host and as storage domains in VMs). I’m seeing significant differences in throughput and latency, especially with GlusterFS and OLVM guest disks. Summary of Results: Location IOPS Bandwidth Total IO Avg Latency Block Size Jobs CPU (sys) Notes Local Brick 1816 1816 MiB/s 109 GiB 587 µs 1M 4 45% Fastest, direct disk OLVM Guest Disk using GlusterFS Storage Domain 117 118 MiB/s 8196 MiB 12.3 ms 1M 4 3.80% Virtualization overhead GlusterFS Mounted on Host 211 211 MiB/s 12.4 GiB 18.8 ms 1M 4 3.50% Improved, but still slower NFS Mount on Host 4241 4242 MiB/s 249 GiB 613 µs 1M 4 80% Fastest network storage OLVM Guest Disk using NFS Storage domain 532 532 MiB/s 32.8 GiB 5.4 ms 1M 4 17.40% NFS on OLVM guest Observation: Both GlusterFS and NFS are on the same network VLAN, but NFS consistently outperforms GlusterFS (both on host and as a storage domain in OLVM). This suggests the network isn’t the bottleneck. The issue may be with GlusterFS configuration, protocol overhead, or OLVM’s handling of storage domains. Questions: Has anyone tuned GlusterFS or OLVM for better performance in similar scenarios? Are there recommended settings or architectural changes to improve GlusterFS throughput/latency? Any best practices for OLVM storage domain configuration (GlusterFS vs NFS)? Is this performance gap expected, or should I look deeper into my setup? Test Details: fio commands used Any advice, tuning tips, or references would be greatly appreciated!

Stream 10 for deploy
by Christoph Köhler 01 Oct '25

01 Oct '25

Dear all, Is there a ready-made stream 10 appliance for engine-deploy that we can use for deployment? And if so, could there be any problems with concurrent use of rocky 9 hosts? We would choose the master snapshot. Greetings from Christoph
