CSM is theoretically supposed to be hardware-agnostic, so I was happy
with it being orthogonal to QEMU. Wasn't that fairly much the idea with
COREBOOT vs. QEMU too? It's more about "direct/native boot on QEMU"
rather than "running on QEMU at all". Which is why the virtio drivers
shouldn't depend on QEMU alone.

You could perhaps introduce a separate config option for 'running on
QEMU at all', and *that* one wouldn't in part of the choice.

Cool, thanks.

Yes, that makes sense. I've chased them up. Not really the OVMF team but
the people who own the *spec* within Intel. Once the spec is fixed, OVMF
can happily implement it.

That's why I made it optional ;)
