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/

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.

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.

Barebone Hosted Engine Deployment fails
by kevin＠kllmnn.de 12 May '25

12 May '25

Hey people, I hope someone can help me identify if there's something I'm doing wrong or if there's a bug. Originally I wanted to re-deploy my self-hosted engine, as it is still on version 4.5.5 with CentOS 8, and therefore can't be updated anymore. To get a fresh backup of the currently running config I did the following: 1. On physical host `hosted-engine --set-maintenance --mode=global` 2. On engine VM `systemctl stop ovirt-engine` and then 3. `engine-backup --scope=all --mode=backup --file=/mnt/ovirt-engine-backup/ovirt-engine-4.5.5-backup.bck --log=/mnt/ovirt-engine-backup/ovirt-engine-4.5.5-backup.log` (where `/mnt/ovirt-engine-backup/` is a NFS share) 4. On physical host `hosted-engine --vm-shutdown` Then I set up a new physical host with CentOS 9 Stream (Build 20250320), enabled and installed the oVirt repository as mentioned at https://www.ovirt.org/download/install_on_rhel.html, then ran: `hosted-engine --deploy --4 --restore-from-file=/mnt/ovirt-engine-backup/ovirt-engine-4.5.5-backup.bck` (of course mounting the NFS share prior to this). But after giving it all the information it needed it fails after 15-20 minutes with several errors in the logfile, which I cannot identify the primary/root cause of. The first error that appears is this one: ``` 2025-03-25 11:19:35,427+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Include after engine-setup custom tasks files for the engine VM] 2025-03-25 11:19:36,730+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Wait for the engine to reach a stable condition] 2025-03-25 11:19:37,431+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 skipping: [localhost] 2025-03-25 11:19:38,133+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Configure LibgfApi support] 2025-03-25 11:19:38,835+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 skipping: [localhost] 2025-03-25 11:19:39,536+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Save original OvfUpdateIntervalInMinutes] 2025-03-25 11:19:42,041+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 changed: [localhost -> 192.168.222.170] 2025-03-25 11:19:42,742+0100 INFO otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:115 TASK [ovirt.ovirt.hosted_engine_setup : Set OVF update interval to 1 minute] 2025-03-25 11:19:45,147+0100 DEBUG otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:109 {'changed': True, 'stdout': 'Index 1 out of bounds for length 1', 'stderr': 'Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false', 'rc': 1, 'cmd': ['engine-config', '-s', 'OvfUpdateIntervalInMinutes=1'], 'start': '2025-03-25 11:19:43.872322', 'end': '2025-03-25 11:19:44.941216', 'delta': '0:00:01.068894', 'msg': 'non-zero return code', 'invocation': {'module_args': {'_raw_params': 'engine-config -s OvfUpdateIntervalInMinutes=1', '_uses_shell': False, 'stdin_add_newline': True, 'strip_empty_ends': True, 'argv': None, 'chdir': None, 'executable': None, 'creates': None, 'removes': None, 'stdin': None}}, 'stdout_lines': ['Index 1 out of bounds for length 1'], 'stderr_lines': ['Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false'], '_ansible_no_log': False, '_ansible_delegated_vars': {'ansible_host': '192.168.222.170', 'ansible_port': None, 'ansible_user': 'root', 'ansible_ connection': 'smart'}} 2025-03-25 11:19:45,248+0100 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:113 fatal: [localhost -> 192.168.222.170]: FAILED! => {"changed": true, "cmd": ["engine-config", "-s", "OvfUpdateIntervalInMinutes=1"], "delta": "0:00:01.068894", "end": "2025-03-25 11:19:44.941216", "msg": "non-zero return code", "rc": 1, "start": "2025-03-25 11:19:43.872322", "stderr": "Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false", "stderr_lines": ["Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false"], "stdout": "Index 1 out of bounds for length 1", "stdout_lines": ["Index 1 out of bounds for length 1"]} ``` The full log is available here: https://filebin.net/dimi5g2o6q20t4aj I also tried with a completely clean deployment, without restoring from backup (once without and once with using `ovirt-hosted-engine-cleanup` in between). The errors in the log are completely the same. Also I tried to use the oVirt Node master experimental ISO (`ovirt-node-ng-installer-4.5.6-2025031111.c9s.iso`), same issue. Does the problem lie somewhere in my answers for the questions asked by the tool? I cannot identify giving any wrong info. Can someone maybe reproduce the issue?

There are a lot of errors regarding legacy cipher while restoring engine backup to RL9 during our migration to 4.5. 2025-04-22 08:35:48,773+0300 DEBUG otopi.plugins.ovirt_engine_setup.ovirt_engine.pki.ca plugin.execute:923 execute-output: ('/usr/bin/openssl', 'pkcs12', '-in', '/etc/pki/ovirt-engine/keys/engine.p12', '-passin', 'pass:**FILTERED**', '-nokeys') stderr: Error outputting keys and certificates 00CE347D1F7F0000:error:0308010C:digital envelope routines:inner_evp_generic_fetch:unsupported:crypto/evp/evp_fetch.c:355:Global default library context, Algorithm (RC2-40-CBC : 0), Properties () RHEL/RL 9 disables the legacy provider for security reasons. What is the best way to solve this problem ? Should i just enable legacy provider in OpenSSL config or re-sign all certs with new ciper (where can i find more information about this) ? Thank you.

Ovirt 4.3 update to Ovirt 4.5 on alma8
by Pavel Šipoš 01 May '25

01 May '25

Hi, I’m working on upgrading an oVirt 4.3 cluster to the latest 4.5 version. So far, I’ve successfully performed a test upgrade of the oVirt Engine from 4.3 (CentOS 7) to 4.4 (AlmaLinux 8.10). I’ve encountered some noVNC issues, as described here: https://forums.oracle.com/ords/apexds/post/olvm-manager-vm-console-novnc-ex… I’ll probably leave this issue unresolved for now, as I’m planning to continue with the upgrade process. For the next step, I’d like to ask if anyone has experience installing and running an oVirt 4.5 cluster (both engine and hosts) on AlmaLinux 8.x. So far, it seems that I might need to upgrade the OS to AlmaLinux 9 as well, possibly using ELevate. If anyone has recently completed a similar migration, I’d really appreciate any tips or recommendations. Best regards, Pavel

oVirt enquiry and installation instructions
by Andreas Giannakopoulos 13 Apr '25

13 Apr '25

Hi all, I have been looking into oVirt and researching possible utilization by my team. I have been through the instructions in the site, on github and the forums. I have attempted both with self hosted using the ISO provided and as a standalone engine installation on a separate server. However I have been getting all kinds of different failures and errors and since I understand that some of the instructions provided could be slightly outdated can you please direct me to the most accurate and recent instructions to follow for setting up and testing the environment? Also is there a new version planned some time soon or should I consider the 4.5.5 version from almost 2 years ago the most recent and updated one?
