Good morning dear community. We are experiencing a problem when taking a backup through Veeam backup. I share the logs: Engine.log 2025-06-03 16:09:52,158-05 ERROR [org.ovirt.engine.core.sso.service.SsoService] (default task-2019) [53762455] OAuthException invalid_grant: The provided authorization grant for the auth code has expired. 2025-06-03 16:09:52,160-05 ERROR [org.ovirt.engine.core.aaa.filters.SsoRestApiAuthFilter] (default task-2006) [] Cannot authenticate using authentication Headers: invalid_grant: The provided authorization grant for the auth code has expired. 2025-06-03 16:09:52,429-05 INFO [org.ovirt.engine.core.sso.service.AuthenticationService] (default task-2006) [] User admin@internal-authz with profile [internal] successfully logged in with scopes: ovirt-app-admin ovirt-app-api ovirt-app-portal ovirt-ext=auth:sequence-priority=~ ovirt-ext=revoke:revoke-all ovirt-ext=token-info:authz-search ovirt-ext=token-info:public-authz-search ovirt-ext=token-info:validate ovirt-ext=token:password-access 2025-06-03 16:09:52,518-05 INFO [org.ovirt.engine.core.bll.aaa.CreateUserSessionCommand] (default task-2006) [60f224da] Running command: CreateUserSessionCommand internal: false. 2025-06-03 16:09:52,530-05 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-2006) [60f224da] EVENT_ID: USER_VDC_LOGIN(30), User admin@internal-authz connecting from '192.168.170.52' using session 'dYQlOCMThsTOInKjX8GKWUpAk/SFspOh5vuX0efK1slxzWloBoK9jGqt7TwOapfxUR1kzGg0ctoofUC7/pjeVg==' logged in. 2025-06-03 16:09:52,784-05 WARN [org.ovirt.engine.api.restapi.util.LinkHelper] (default task-2006) [] Can't find relative path for class "org.ovirt.engine.api.resource.StorageDomainVmDiskAttachmentsResource", will return null 2025-06-03 16:09:52,784-05 WARN [org.ovirt.engine.api.restapi.util.LinkHelper] (default task-2006) [] Can't find relative path for class "org.ovirt.engine.api.resource.StorageDomainVmDiskAttachmentsResource", will return null 2025-06-03 16:10:05,258-05 INFO [org.ovirt.engine.core.sso.servlets.OAuthRevokeServlet] (default task-2006) [] User admin@internal-authz with profile [internal] successfully logged out 2025-06-03 16:10:05,267-05 INFO [org.ovirt.engine.core.bll.aaa.TerminateSessionsForTokenCommand] (default task-2019) [78785b84] Running command: TerminateSessionsForTokenCommand internal: true. 2025-06-03 16:10:05,305-05 INFO [org.ovirt.engine.core.sso.servlets.OAuthRevokeServlet] (default task-2006) [] User admin@internal-authz with profile [internal] successfully logged out 2025-06-03 16:10:05,310-05 INFO [org.ovirt.engine.core.bll.aaa.TerminateSessionsForTokenCommand] (default task-2019) [4a6cfc6] Running command: TerminateSessionsForTokenCommand internal: true. 2025-06-03 16:10:28,401-05 INFO [org.ovirt.engine.core.sso.service.AuthenticationService] (default task-2006) [] User admin@internal-authz with profile [internal] successfully logged in with scopes: ovirt-app-admin ovirt-app-api ovirt-app-portal ovirt-ext=auth:sequence-priority=~ ovirt-ext=revoke:revoke-all ovirt-ext=token-info:authz-search ovirt-ext=token-info:public-authz-search ovirt-ext=token-info:validate ovirt-ext=token:password-access 2025-06-03 16:10:28,453-05 INFO [org.ovirt.engine.core.bll.aaa.CreateUserSessionCommand] (default task-2006) [152dcb43] Running command: CreateUserSessionCommand internal: false. 2025-06-03 16:10:28,466-05 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (default task-2006) [152dcb43] EVENT_ID: USER_VDC_LOGIN(30), User admin@internal-authz connecting from '192.168.170.52' using session '1WDL5jCeJNVnQCOSAJu8hd+M1IJJp5AChx3SQnpNjG+v2cZHNRYBsrQpmfhNAuB5KAHUun7HKUxbRQcs5OCalQ==' logged in. 2025-06-03 16:10:50,031-05 WARN [org.ovirt.engine.core.utils.virtiowin.VirtioWinReader] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-19) [6b0bdae7] Directory '/usr/share/virtio-win' doesn't exist. --------- Veeam Proxy: 2025-06-03 16:10:21.0156 00023 [194115] ERROR | [RhvCluster][myengine.co]: <== Request "Get" "https://myengine.co/ovirt-engine/api/vms/0a5b4e0e-477c-494a-ba43-1e6c48565a…", body: "{}" 2025-06-03 16:10:21.0156 00023 [194115] ERROR | [RhvCluster][myengine.co]: ==> Response "Get" "https://myengine.co/ovirt-engine/api/vms/0a5b4e0e-477c-494a-ba43-1e6c48565a…", "code: 401", duration: "163 msec", body: "[binary data]" Note that the user I use is admin@internal.

Re: Network Performance Issue on oVirt Node Using Intel Platinum 8562Y+ (Sapphire Rapids) CPU
by domien.vanrompaey＠dynamate.be 24 Jun '25

Hi My issue was solved by updating the firmware on our Broadcom BCM57504 NIC (buggy firmware was 23.11.16.22). I also had to add the following option via ethtool for the NICs that were serving the bond: --offload eno12419np2 gro off --offload eno12429np3 gro off . This completely solved my problems. Maybe this can be relevant for your issue too.

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

Network Performance Issue on oVirt Node Using Intel Platinum 8562Y+ (Sapphire Rapids) CPU
by dhayanands＠botvfx.com 17 Jun '25

Hi team, We’re facing a strange issue with network performance on one of our oVirt hosts and would like to get insights or guidance on possible misconfigurations or compatibility problems. Environment Details: oVirt Version: 4.5.5 Cluster CPU Type: Intel IceLake Server Family (default) Host A (Issue observed): CPU: Intel Xeon Platinum 8562Y+ (Sapphire Rapids) CPU Family/Model: Family 6 / Model 207 / Stepping 2 Host B (Working fine): CPU: Intel Xeon Gold 6354 (Ice Lake) CPU Family/Model: Family 6 / Model 106 / Stepping 6 Problem Description: We have a VM (kitsu) that was initially hosted on botovirtnode-006 (Platinum 8562Y+). The VM showed very poor download speeds (~10 Mbps), while upload was fine (~680 Mbps). After migrating the same VM to another host (botovirtnode-001 with Gold 6354 CPU), network performance drastically improved: Test On Affected Node On Healthy Node Download ~10 Mbps ~920 Mbps Upload ~680 Mbps ~760 Mbps This clearly indicates a host-specific issue, most likely related to hardware compatibility or CPU feature masking. Troubleshooting Done: Verified VM configurations (same on both hosts). Tested with speedtest-cli multiple times to confirm. Confirmed that VM virtual NIC, vNIC profile, and vSwitch settings are identical. Both hosts are part of the same cluster using the default Intel IceLake Server CPU type. Suspect the issue is due to CPU feature mismatch or unsupported stepping/model in the cluster’s CPU type.

Hi there I was just about to post a similar issue when I saw your post. We have a cluster of 3 AMD EPYC 9454 48-Core Processor hosts who have BCM57504 NICs in a LACP bond to 2 Dell S5248F-ON switches. We are seeing assymetrical network performance between VM's making the cluster unusable. In previous test setups we did not have this issue. The issues seems to manifest only for traffic between hosts over VLAN networks and SDNs do not seem to be affected. If we do an upload test over a virtual firewall we get the same numbers as you do. If we do some iperf tests we get this: (We will use the name VM1 and VM2 who are in the same VLAN network. For hosts we will use Host1 and Host2 in the names) VM1: 10.22.21.10 VM2: 10.22.21.20 VM1 (Host2) to VM2 (Host1) [cid:image002.png@01DBDEA1.6BFA2C60] VM2 (Host1) -> VM1 (Host2) [cid:image003.png@01DBDEA1.6BFA2C60] When we put these on the same host (Host2) VM2 -> VM1 [cid:image004.png@01DBDEA1.6BFA2C60] VM1->VM2 [cid:image005.png@01DBDEA1.6BFA2C60] I’m believing the underlying issue will be the same. If it’s not I will probably split my issue in a seperate post. We raised a ticket with Oracle Support for this (we are running OLVM, latest version) but it’s going very slow. The issue is stopping us from bringing our cluster into production.

Unable to Start the Hosted Engine and the WebUI
by kelwintai＠proton.me 13 Jun '25

13 Jun '25

Hi there, I have tried to restart the Hosted Engine but I cannot ssh/ping the Hosted Engine after the restart. The oVirt webUI was down and I cannot start the VM in both GUI and CLI. I have used command "hosted-engine --console" to start a console but error message "Cannot find character device <null>" was prompted. I also checked the status of the Hosted Engine and the its state was "EngineStarting". However, the Hosted Engine will keep restarting in the same host automatically. Please help 1. Is there any commands that I can use to start the VM inside the Hosted Engine CLI. 2. Does anyone know why my Hosted Engine cannot be started successfully and accessed via CLI. Thank you for your help. KT

What is the future of oVirt?
by Giacomo Failla 10 Jun '25

10 Jun '25

Hi everyone, I’m writing this post because I think many of us are asking the same questions these days. Over the past few months, we’ve seen some big changes in the open source virtualization world. Red Hat’s decision to discontinue RHV and slow down upstream oVirt development has understandably created a lot of uncertainty — especially for those of us running critical infrastructure on top of oVirt. In this changing landscape, I’m wondering: how is the oVirt project doing today? Is there still an active roadmap? Are there developers and organizations continuing to contribute? And most importantly — what can we as a community do to help ensure that oVirt remains a solid and well-maintained option in the years ahead? At the end of the day, many of us need to make decisions about how to evolve our IT environments, and having clarity on whether oVirt will continue to be a reliable choice is really important. I’d love to hear from anyone close to the project or involved in development. Any updates, insights, or thoughts would be greatly appreciated. Thanks to everyone for your work and contributions to this community. Best regards, Giacomo Failla Head of Technology — Cheope SA
