So just to update/reconfirm something, qemu-system-amd64 fails on systems with more than 288 cores, regardless of how you've configured the KVM Guest.

We have had them test both the default (which defaults to 1 vCPU), and by explicitly setting the config to a single vCPU. We have NEVER launched a KVM guest that was handed more than 1 CPU core, as we have always used the default config for simplicity.

Currently, this causes certification tests on systems with high end AMD CPUs to fail, as those have far more than 288 cores.

We do not have a system currently in house to test this with, but we can get our OEM partner to test patched versions of packages that address this. I have also raised this directly with AMD.
