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.

Few hosts shows unable to launch vms due memory is not available to schedule vm. However vm has enough memory when check free command. If any one come across such issue, please let me know how we can fix it in oracle olvm

Veeam - Move data over other network than ovirtmgmt
by domien.vanrompaey＠dynamate.be 18 Jun '25

18 Jun '25

Hi all I was wondering if anyone managed to get Veeam working with a dedicated backup VLAN instead of sending traffic over the ovirtmgmt interface. We have an OLVM setup (version 4.5.5-1.42.el8) with 3 hosts in 1 cluster for now. Each host has a 1Gbps NIC pair in a seperate management LAN that is only used for ovirtmgmt Each host also has a 10Gbps NIC Bond where all the VLAN's are trunked including a dedicated Backup VLAN. The hosts do not have an IP in this Backup VLAN configured (is this needed?) Each host also has 2 NICs dedicated to storage backend (iSCSI Multipathing) Our Veeam Appliance and workers are setup in the Backup VLAN and they can communicate with the backup repository that is also in this VLAN. When we take a backup, however, we see that the ovirtmgmt network is maxed out on trafic, which probably shouldn't happen. We come from a VMWare environment where the backup proxies handle all the trafic through the backup VLAN without relying on the management network and I was expecting it to work similarly Has anyone managed to get this working as I envision it? Or is the solution to simply link ovirtmgmt to the 10Gbps bond and skip the dedicated mgmt networking? I've also opened a ticket with Veeam for this, but for now I'm just getting questions from them and no real answers. If I get a useful solution from them I will also post it here

ovirt-hosted-engine deploy hangs
by bleuze＠enkon.com 02 Jun '25

02 Jun '25

This is on a brand new Oracle Linux ver8.10 install on a physical server. I have completed all the perquisite steps in the instructions at https://docs.oracle.com/en/virtualization/oracle-linux-virtualization-manag… I run the deployment script: hosted-engine --deploy --4 Answer all the questions and let it run. It runs for about an hour and then hangs at the step: [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Create temporary lock file] [ INFO ] changed: [localhost -> localhost] [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Pause execution until /tmp/ansible.yo6aij1p_he_setup_lock is removed, delete it once ready to proceed] The first time I let it run all night and it was still hung in the morning. I have tried this using the cli command above. I have also tried it using the cockput gui method, both procedures hang at the same place. I have to run /usr/sbin/ovirt-hosted-engine-cleanup after each failure before trying again I can't find any clues in the logs but perhaps someone can tell me what to look for. I am happy to post the logs here as well. I assume this is at the point where the temporary Self Hosted engine has been created and is ready to be migrated to the shared storage. The lock placed there until it is successfully moved. But the instructions say that I should be prompted for the "storage you would like to use" I don't get that promtp. It is hung somewhere before it gets to that stage. What I do know is that the temporary Self hosted engines is created because I can ssh into and login as root Next I will try again but this time use the --ansible-extra-vars option to fill in all the variables at the beginning. I don't know what else to try

I'm currently experiencing a usage issue. I'm unable to access the Console via web browser. A banner appears at the top stating: 'Something went wrong, connection is closed.' Upon further investigation, I found that the ovirt-websocket-proxy service shows the following message: handler exception: [SSL: TLSV1_ALERT_UNKNOWN_CA] tlsv1 alert unknown ca (_ssl.c:897) OS Version: Oracle 8.10 Ovirt engine: 4.4

Potential CentosStream 9 resilientstorage repo issues
by lmd＠gto.net 26 May '25

26 May '25

Good Morning! I wanted to report that I think there are issues with CentOS Stream 9 ResilientStorage repos (added by package "ovirt-release-ovirt45" and also enabled in the hosted-engine appliance) that causes anything related to DNF and this repo to fail as captured below. Digging in, it looks like centos.org is advertising a metalink.xml (at least for my Toronto, Ontario location) that is timetamped 1747062205 (Monday, May 12, 2025 3:03:25 PM GMT). Mirrors are not in good shape: * centos.org themselves are advertising a repomd.xml for ResilientStorage with timestamp 1747752818 (Tuesday, May 20, 2025 2:53:38 PM) * ca.mirrors.cicku.me are advertising an identical repomd.xml of centos.org * mirror.cpsc.ucalgary.ca is advertisting a 0-byte repomd.xml * mirrors.lug.mtu.edu is advertising an old repomd.xml of timestamp 1744645925 (Monday, April 14, 2025 3:52:05 PM) The SHA512 sum of all published repomd.xml files does not match metalink, therefore all mirrors fail. I haven't tried to exclude the repo from the HE but I wanted to post a note here in case someone else is running into this. I anticipate that Centos.org will fix this at some point, but based on dates it could be that this has been broken for ~3 days already (2025-May-20 2:53PM GMT). I am not sure where to post to raise awareness with CentOS.org or the group responsible for the ResilientStorage repo. If someone knows please let me know - or if someone on the oVirt team could notify a contact, I would be obliged if you could let them know.

Re: [External] : Re: hosted-engine --deploy fails with "The task includes an option with an undefined variable. The error was: 'local_vm_ip' is undefined"
by Marcos Sungaila 16 May '25

Hi Glenn, The playbooks are not compatible with newer ansible versions, try downgrading the ansible/ansible-core package in use. Or you can go deeper and review the playbooks to make it compatible with the ansible version in use.
