CentOS9 Stream -- Only way forward?
by eshwayri＠gmail.com
I've been running 4.5.4-1 on RHEL8 for a while now; been running fine for my needs. I was getting around the unholy dependency issue caused by the centos-release package conflicting with the redhat-release package by upgrading everything else -- not it. It's been necessary to do this since RHEL versions were higher than any CentOS 8 Stream versions. This time round since CentOS has been archived, I made sure to install anything I hadn't and then manually purged centos-release from the rpm database. This allowed RHEL to update to 8.10, including the release package this time. Not expecting an issue since there won't be any future patches coming from that repo.
If I decide to stick with oVirt and install daily snapshots, I assume what I will have to do is setup a new CentOS Steam 9 server, create a backup of the old server, and then restore on the new server. Like what I did when I was forced to migrate from CentOS 8 to RHEL8 (with CentOS 8 Stream packages). Is this right?
I haven't decided if I want to do this. CentOS Stream 9 is supported until mid 2027; RHEL 8.10 is supported until mid 2029. Barring any new features or major incompatibility, I really don't see a pressing reason to do this. In fact, with no one stepping in to take over the project, there is a better chance of being supported by sticking with RHEL 8.10 (2+ years).

Re: Multiple GPU Passthrough with NVLink (Invalid I/O region)
by Zhengyi Lai
I noticed this document https://docs.nvidia.com/vgpu/16.0/grid-vgpu-release-notes-generic-linux-k... has this to say
In pass through mode, all GPUs connected to each other through NVLink must be assigned to the same VM. If a subset of GPUs connected to each other through NVLink is passed through to a VM, unrecoverable error XID 74 occurs when the VM is booted. If a subset of GPUs connected to each other through NVLink is passed through to a VM, unrecoverable error XID 74 occurs when the VM is booted. This error corrupts the NVLink state on the physical GPUs and, as a result, the NVLink bridge between the NVLink and the physical GPUs is not recognized. result, the NVLink bridge between the GPUs is unusable.
You may need to passthrough all GPUs in the nvlink to the VM

Certificate verification error for qemu while migrating
by Julien Deberles
Hello,
I'm running ovirt 4.4.10 and I have the following error while I launch a VM migration :
Jul 3 12:37:07 ssc-sati-02 journal[958949]: Certificate [session] owner does not match the hostname myhostname
Jul 3 12:37:07 ssc-sati-02 journal[958949]: Certificate check failed Certificate [session] owner does not match the hostname myhostname
Jul 3 12:37:07 ssc-sati-02 journal[958949]: authentication failed: Failed to verify peer's certificate
Jul 3 12:37:07 ssc-sati-02 journal[958949]: operation failed: Failed to connect to remote libvirt URI qemu+tls://myhostname/system: authentication failed: Failed to verify peer's certificate
To avoid this error I set the following paramaters inside the /etc/libvirt/qemu.conf and restard vdsmd daemon.
migrate_tls_x509_verify = 0
default_tls_x509_verify = 0
But I still have the same error. Can you help me to understand why this set of parameters are not working as exepected ?
kind regards,
Julien

oVirt 4.5.6-1.el9 standalone engine - older VM's on centos 6 or rhel 6 hangs on live migration with ovirt node 5.14.0-388.el9.x86_64
by Sumit Basu
Hi All,
In our new oVirt 4.5.6-1.el9 cluster we find older vm's on el6 (centos/rhel) keeps hanging after live migrations. we find this typically with el6 vm's, our other el'7 and windows vm's do not face this issue.
All these VM's were imported from an oVirt 4.3.10.4-1.el7 cluster by importing the storage domain into the new cluster. Initially we installed all the latest ovirt-node-ng-installer-latest-el9 on all our nodes(8 of them) and we found this live migration hang issue, later we installed ovirt-node-ng-installer-4.5.2-2022081013.el9 on the nodes and tested - we found the issue resolved and we could migrate the el6 vm's without any issues at all, later, after doing an upgrade on the nodes we find the issue has come back again.
The nodes where there are no live migration issues have kernel 5.14.0-142.el9.x86_64, the nodes with the latest version 5.14.0-388.el9.x86_64 seems to have this issue.
Has anybody faced this issue? - any patches needed/available?
Thanks
