oVirt CLI tool for automation tasks
by munnadawood＠gmail.com 29 Jun '26

29 Jun '26

We recently migrated from VMware to oVirt. I am looking for any CLI tool well suited for my automation tasks like VM create, clone, migrate 100s of Virtual machines in oVirt cluster. with VMware I was using govc (vSphere CLI built on top of govmomi). Another option I read is powercli, quite unsure if it works with oVirt. Any suggestions would be highly appreciated. Thanks!

Deploy process frezzes with "Wait for the host to be up"
by Leandro Pereira 16 Feb '26

16 Feb '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.

Hosted Engine Deployment timeout waiting for VM
by Jonas Liechti 09 Feb '26

09 Feb '26

Hello users, I am currently trying to deploy the self-hosted engine via the web interface but it seems stuck at the task "Wait for the local VM" (https://github.com/oVirt/ovirt-ansible-collection/blob/master/roles/hosted_…) I am unsure what to look at for getting more info as I haven't worked a lot with Ansible before. Do you have any idea how to debug? The temporary IP is added to /etc/hosts and I can also login to the VM via SSH: [root@server-005 ~]# cat /etc/hosts 192.168.1.97 ovirt-engine-test.admin.int.rabe.ch # temporary entry added by hosted-engine-setup for the bootstrap VM 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.128.16.5 server-005.admin.int.rabe.ch 10.128.16.6 server-006.admin.int.rabe.ch 10.128.16.7 server-007.admin.int.rabe.ch #10.128.32.2 ovirt-engine-test.admin.int.rabe.ch 10.132.16.5 server-005.storage.int.rabe.ch 10.132.16.6 server-006.storage.int.rabe.ch 10.132.16.7 server-007.storage.int.rabe.ch [root@server-005 ~]# ssh ovirt-engine-test.admin.int.rabe.ch root(a)ovirt-engine-test.admin.int.rabe.ch's password: Web console: https://ovirt-engine-test.admin.int.rabe.ch:9090/ or https://192.168.1.97:9090/ Last login: Mon Apr 18 11:33:53 2022 from 192.168.1.1 [root@ovirt-engine-test ~]# ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 00:16:3e:58:7a:a3 brd ff:ff:ff:ff:ff:ff inet 192.168.1.97/24 brd 192.168.1.255 scope global dynamic noprefixroute eth0 valid_lft 2313sec preferred_lft 2313sec inet6 fe80::216:3eff:fe58:7aa3/64 scope link valid_lft forever preferred_lft forever Thank you for any tips for debugging.

VM Template Reuse Between Clusters
by lmd＠gto.net 28 Jan '26

28 Jan '26

Good Morning! I recently added a second cluster to an oVirt environment and I am looking to re-use a number of templates between the clusters while providing self-service to users through the VM Portal. I would like to describe what I am seeing and ask whether you might know of what I am missing - or if you could share your experience. For sake of discussion, let us call the clusters "CORE" and "PROD" (the new cluster) and the template "UbuntuServer24". The template was created in cluster CORE against Storage Domain "CORE1". The template is visible to all users (role "UserTemplateBasedVm" for Everyone). CORE and PROD clusters contain the same networks and the hosts mount the same Storage Domains though, by policy, PROD cluster users are restricted to creating Disks only on Storage Domain "PROD1" through roles/permissions. User JDOE is a PROD cluster user, has VM Portal/"User role" rights to the cluster and Storage Domain and is able to deploy and manage VMs in Cluster PROD. JDOE is not intended to have any permissions against Cluster CORE. JDOE has temporary Admin Portal rights but I would prefer they operate through VM Portal at all times. Here is what I am seeing: Using the Administrator Portal, JDOE can deploy template UbuntuServer24 in PROD without any trouble. Using the VM Portal, using "Create Virtual Machine", JDOE does not see the "UbuntuServer24" template in the list of available templates. It appears to be filtered out of the list. Based on research so far, I can create a second copy of the template (ex: deploy a VM and capture a template in cluster PROD) as different name "UbuntuServer24-PROD". With no other changes, user JDOE can successfully deploy this new template into cluster PROD via VM Portal. I think this proves JDOE permissions and roles are in good shape. For testing I have also temporarily added equivalent permissions for JDOE against Cluster CORE and can confirm that the "UbuntuServer24" is only displayed as a Template when cluster "CORE" is selected as the target for the new VM in the "Create Virtual Machine" flow. The duplicated template approach does work but it means that there are two templates to offer the same result in each of the two clusters. I am concerned that this leaves an opportunity for de-sync, some additional storage consumption, and an enforced requirement for a different template name (string) which complicates user-facing documentation. Ideally I would like to maintain a single template to keep things simple and make it easy for other team members to use and maintain the environment. I tried to find a reference to my query in the docs as well as web search but didn't come up with something I was confident was on the right path. Is there a way to reuse templates between clusters in this manner and, if so, could you kindly please point me in the right direction? Thank you very much for any advice you may have, Dan Galway

Upgrading self-hosted engine from 4.5.6 on Stream 8
by Devin A. Bougie 27 Jan '26

27 Jan '26

Hi, All. If possible, I’d greatly appreciate an overview of the recommended procedure for upgrading a self-hosted engine setup from 4.5.6 on CentOS Stream release 8 to 4.5.7. All of our hosts are running fully-updated AlmaLinux 9. When we initially setup our cluster, this gave us a self-hosted engine running CentOS Stream release 8. As 8 is no-longer supported, it seems the first step for upgrading our cluster from 4.5.6 to 4.5.7 is to update the engine to Stream 9 (or 10)? Has anyone else completed this upgrade, and does this look like the right approach? 1. Put the cluster in global maintenance: hosted-engine --set-maintenance --mode=global 2. Stop ovirt-engine on the engine VM: systemctl stop ovirt-engine.service 3. Backup the engine: /usr/bin/engine-backup --mode=backup --scope=all --file="/var/lib/ovirt-engine-backup/backup.tar.bz2" --log=/var/log/ovirt-engine-backups.log 4. From an existing host, deploy a new engine: hosted-engine --deploy --restore-from-file=backup.tar.bz2 5. From the new engine, re-install each existing host. If that looks correct, is there anything we need to do for the existing hosts that are running many VMs in addition to the hosted engine? Should we expect to be able to deploy a new engine and update each host to 4.5.7 without downtime for any running VMs? Many thanks, Devin

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.
