Good afternoon, I have version 4.4.3 and want to upgrade to at least 4.4.10 but I am facing this error: [root@ovirt1 ~]# yum update Failed to set locale, defaulting to C.UTF-8 Last metadata expiration check: 2:05:22 ago on Tue Feb 7 12:31:28 2023.

Good afternoon, Since installing ovirt, there have been problems with OVN Provider. But we didn't do it, and we didn't have to. Now we need to create virtual networks, but nothing works for us. Please help with thoughts.

New oVirt HCI 4.5.4 Cluster Problems
by Clint Boggio 14 Feb '23

14 Feb '23

Good day all. I'm in the process of deploying a fresh, new cluster and i'm running into a few snags. I'm trying to use the cockpit environment to deploy the gluster storage setup as I have previously done and it's failing consistently. I looked through what I believe to be the current documentation and I don't see anything about HCI setup, and the Gluster storage documentation points to the Gluster community web presence. So, my question is, will the oVirt HCI deployment still be supported, and is the process the same with cockpit to configure the storage, and cli to deploy the hosted engine or did HCI and gluster not make the cut with the 4.5.4 release? I'm using the oVirt node installation iso from the oVirt site for this deployment.

future of oVirt after end of road for CentOS. (porting)
by rp.neuli＠yahoo.com 12 Feb '23

12 Feb '23

Hello Masters, I am very keen to use oVirt, but I was shocked and shaken to go ahead with oVirt after I heard about end of road for CentOS. Therefore I looked for some answers which I could not find online: 1. Will/Are you actively and vigorously porting: a) oVirt Agent to other OS like ubuntu? b) vdsm package to other OS like ubuntu, deb, openBSD etc. 2. While standalone oVirt Node can continue to have CentOS codebase under the hood. But do you still want to migrate it to other OS? like openBSD? Kindly advice. In my view, oVirt in itself is a good and complete platform. It just need to continue evolve as VM and container "OS"/hypervisor. At the same time 'agent' and vdsm should be ported to as many OS as possible. Thank you. Rajeev

oVirt 4.5 console problem with Ubuntu 22.04 guest
by Kalil de A. Carvalho 12 Feb '23

12 Feb '23

Hello all. Today I had a problem trying to connect with some VM's using console vnc, through user portal, informing us that other one was connected already, asking if we want to connect anyway, and after we accepted it show us a information that was not possible connect, that has some problem synchronize with de SSO, that is probably error with the guest agent. We tried restarting the agent but had the same result. Just after shutdown and starting again all things worked fine. We looked for any firewall rule, errors between communication and we did not find anything. Does anyone have this kind of problem? We have other O.S and distribution working fine here, just have this problem with Ubuntu 22.04. Best regards -- Atenciosamente, Kalil de A. Carvalho

ImageIO Performance
by Jean-Louis Dupond 11 Feb '23

11 Feb '23

Hi All, We backup our VM's with a custom script based on the https://github.com/oVirt/python-ovirt-engine-sdk4/blob/main/examples/backup… example. This works fine, but we start to see scaling issues. On VM's where there are a lot of dirty blocks, the transfer goes really slow (sometimes only 20MiB/sec). At the same time we see that ovirt-imageio process sometimes uses 100% CPU (its single threaded?). Is this known behavior? Are there ways to optimize imageio? Or any other ways to improve the download speed? Thanks Jean-Louis
