oVirt 4.5.0.8-1.el8 I tried to connect to grafana via the monitoring portal link from the dash and all panels are failing to display any data with varying error messages, but all include 'Origin Not Allowed' I navigated to Data Sources and ran a test on the PostgreSQL connection (localhost) which threw the same Origin Not Allowed error message. Any suggestions?

Cannot successfully import Windows vm to new ovirt deployment
by netracerx＠mac.com 29 Nov '23

29 Nov '23

I am running into an issue that, from what little Google-fu I've been able to use, should be solved in oVirt 4.5. I'm trying to import WS2019 VMs from ESXi 7 as OVFs or even OVAs. But when I do the import and set the OS to Windows Server 2019 x64 in the admin portal, I get the error "Invalid time zone for the given OS type ". If I leave it at Other OS, the import fails with event ID 1153. I've been banging my head against this for over a week (previously couldn't get the management VM to complete setup), so any guidance is appreciated. Let me know what to pull to help me pin this down? BTW, yes this is a self hosted install as a nested VM on ESXi. Kinda have to right now to test everything (easiest for me over doing a bare metal on my old PowerEdge 2900 at the moment). Running CentOS 9 Stream.

Gluster: Ideas for migration
by jonas＠rabe.ch 10 Nov '23

10 Nov '23

Hello I have to migrate the Gluster volumes from an old oVirt cluster to a newly built one. I looked into migration strategies, but everything that Red Hat recommends is related to replacing old bricks. In a testing environment I created two clusters and wanted to migrate one volume after the other. Unfortunately that fails because a node cannot be part of two clusters at the same time. The next thing I see, is to recreate the volumes on the new cluster, then constantly rsync the files from the old cluster to the new one and at a specified point in time make the cut over where I stop the applicaiton, do a final rsync and remount the new volume under the old path. Is there any other, nicer way I could accomplish migrating a volume from one Gluster cluster to another?

Engine on EL 9
by David Carvalho 09 Nov '23

09 Nov '23

Hello, good morning. I’m using Oracle Linux and I intended to install a virtualization platffom with KVM and oracle VM. The Oracle documention only mentions Oracle Linux 8 and there are no oVirt repositories available for OL 9. I visited ovirt.org site and at the download page it only mentions: Engine: * Red Hat Enterprise Linux 8.7 (or similar) * CentOS Stream 8 I still had no reply at Oracle foruns. Will there be a possibility to use this with Oracle Linux 9 soon? I have 3 servers to install and I also intend to use Gluster FS. Thanks and regards.

VMs randomly pause due to unknown storage error, unable to resume
by Jon Sattelberger 09 Nov '23

09 Nov '23

Hi, > VM xxx has been paused due to unknown storage error. > Migration failed due to a failed validation: [Migrating a VM in paused status due to I/O error is not supported.] (VM: xxx, Source: yyy). Up until recently oVirt 4.5.4 has been running fine on our RHEL 8 hypervisors with primarily (and a few appliances) Linux guests. We started to add Windows 2019 VMs to the cluster with the guest agent installed. They seem to run fine at first, but some of the Windows VMs may randomly pause due to an unknown storage error. The VM cannot be resumed through the UI or virsh. The paused VM cannot be migrated to another Hypervisor. The GlusterFS storage volumes seem fine. Resetting the VM seems to work, but eventually it'll become paused again. The only thing that came to my mind is the virtual hard disks are thin provisioned. Is a preallocated disk necessary for Windows VMs? Any helpful hints on where to look next is greatly appreciated. Thank you, Jon

Hosted-engine restore failing when migrating to new storage domain
by Devin A. Bougie 08 Nov '23

08 Nov '23

Hello, We have a functioning oVirt 4.5.4 cluster running on fully-updated EL9.2 hosts. We are trying to migrate the self-hosted engine to a new iSCSI storage domain using the existing hosts, following the documented procedure: - set the cluster into global maintenance mode - backup the engine using "engine-backup --scope=all --mode=backup --file=backup.bck --log=backuplog.log" - shutdown the engine - restore the engine using "hosted-engine --deploy --4 --restore-from-file=backup.bck" This almost works, but fails with the attached log file. Any help or suggestions would be greatly appreciated, including alternate procedures for migrating a self-hosted engine from one domain to another. Many thanks, Devin

How to start QA and testing work in the oVirt project?
by song_chao＠massclouds.com 06 Nov '23

06 Nov '23

Hello everyone, I am a testing and development engineer who has been working for 10 years. I want to learn and participate in Ovirt's testing work, and make my own contribution. Through learning and understanding, I believe that in the near future, I can also make some contributions to the ovirt community. Currently, I would like some information about QA and testing processes and methods. Can anyone provide me with it? Thank you.
