Awesome! I'm prepared to eat my words :)

On the subject of TX mitigation, can we please set a standard
on how we measure it? For instance, do we bind the the backend
qemu to the same CPU as the guest, or do we bind it to a different
CPU that shares cache? They're two completely different scenarios
and I think we should be explicit about which one we're measuring.

Thanks,
