Hello
After updating a hypervisor with qemu-kvm-9.0.0-4.el9.x86_64 live migration stopped
working with errors related to the cpu topology.
When I downgraded to qemu-kvm-9.0.0-3.el9.x86_64 migration worked again.
Is this a known bug? Has anyone else encountered this?

Unfortunately I've encountered the same issue. I've decided to stay on
qemu-kvm-9.0.0-4.el9 and restarted all VMs on hosts with the new
version.
However, the update from 9.0.0-4 to 9.0.0-6 was flawless and did not
break VM live migration.
Ciao

That is a qemu bug.
Can you send the exact error and eventually the domain xml/args?
Needs to be fixed in the qemu-kvm packages.
