Hi guys,
I just faced a problem after updating a host. I cannot migrate VM to
updated host.
Here's the error I see trying to migrate a VM to that host.

Instead I can start VM on that host, and migrate away VM from that host.
Rolling back to ovirt-node-ng-4.4.9.1-0.20211207.0+1 via host console
restores full functionality.
The affected version is ovirt-node-ng-4.4.9.3-0.20211215.0+1 (and also
previous one, I don't remember precisely, it was another async release).
Any ideas?
TIA,

New subject: Unable to migrate VMs to a newly upgraded Ovirt node host
+Arik Hadas <ahadas(a)redhat.com> can you suggest a workaround here? Giving
context:
4.4.9.1 shipped qemu-kvm 6.1 and libvirt 7.9.0
4.4.9.2 downgraded qemu-kvm to 6.0 due to pcie bug
4.4.9.3 upgraded libvirt to 7.10 as it was released in CentOS Stream.
So it seems a migration problem between 6.1/7.9 -> 6.0/7.10
qemu-kvm 6.2 got released upstream
https://www.qemu.org/2021/12/14/qemu-6-2-0/ but it's not yet available in
CentOS Stream.

New subject: Unable to migrate VMs to a newly upgraded Ovirt node host
Hi to all, we have the same problem.
we are tryng to migrate some VM from:
qemu 6.1 /libvirt 7.8
to
qemu 6.0 /libvirt 7.10
We cannot maintain qemu61, because one of this vm crash on snapshot remove.
How can we have a stable version of quemu(6.0?) and the live migrate
functionality?
