Offline installation - is is possible?
by postecom＠gmail.com 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

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

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.

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.
