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

Do we have RV tool for ovirt similar to vcenter. Trying to fetch VM, Host information and its metadata information.

Hi, I am trying to fetch vms,hosts and other component information for reference purpose. However seems like RV tool does not support ovirt. So checking if we have any other way to fetch those information in one api call. Tried builtin grafana but it does not give host information where vm resides.

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kinds of different failures and errors and since I understand that some of the instructions provided could be slightly outdated can you please direct me to the most accurate and recent instructions to follow for setting up and testing the environment?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?

How to modify the MAC address of a bonding interface after changing the nic card
by wodel youchi 02 Apr '25

02 Apr '25

Hi, ovirt 4.4 on centos 8. We have changed the network card of a hypervisor which uses bonding interface. The bonding interface still uses the old MAC address of the former slave interface. We tried to modify it via CLI but it didn't work, as soon as the node (hypervisor) is activated, the old MAC is reestablished. it seems to be backed up somewhere. Should we reinstall the host? Regards.

graphical console strange issue - certificate's owner does not match hostname - IP address (ovirt 4.5.6)
by eson＠inux.cz 01 Apr '25

01 Apr '25

Dear proud RHV/Ovirt Hackers, facing strange issue with graphical console - do you have any tips? We successfully run many different clusters, most of them are similar (versions, hw setup). On single one of those, we are facing issue with opening graphical console: Many other clusters are the same setup, the same number of hypervisors, the same versions of OS, packages, ovirt-engine OS, versions and packages... ...and graphical console opens fine. The graphical console setup is the same at all places also: We did comparison of 'console-1.vv' content over many clusters and its content is totaly the same with the faulty one. Meaning there is never hostname, there is always an IP address (not hostname) as the "The certificate's owner does not match hostname 'IP-address'" says: Any tips howto fix this? Best regards Charles Stellen

Re: not able to upload disks, iso - Connection to ovirt-imageio service has failed. Ensure that ovirt-engine certificate is registered as a valid CA in the browser.

Observed in 3rd party Firewall monitoring log files that during the Test Connection, the PC Client is trying to reach the Engine Portal in port 54322, instead of 54323 (Image I/O Proxy) Confirmed in engine-config, that ImageTransferProxyEnabled is set to False. SOLUTION To confirm that the ImageTransferProxyEnabled is set to "false", login in the OLVM Engine Host/VM as root, and execute the following command: # engine-config -g ImageTransferProxyEnabled Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false ImageTransferProxyEnabled: false version: general <<< set to false To enable the Image I/O Proxy and restart the ovirt-engine and ovirt-imageio services perform the following as root: # engine-config -s ImageTransferProxyEnabled=true Picked up JAVA_TOOL_OPTIONS: -Dcom.redhat.fips=false ImageTransferProxyEnabled: true version: general <<< set to true # systemctl restart ovirt-engine # systemctl restart ovirt-imageio

If I install the engine on physical host all work fine and the installation done without problems. Does anyone have any idea why I find the old, now decommissioned, Centos site in the engine configuration? Tnx
