I don't think we should shift this mess into the kernel..

We have a wide range of things now that the orchestration must do in
order to prepare that are fairly device specific. I understand in K8S
configurations the preference is using operators (aka user space
drivers) to trigger these things.

Supplying a few extra qemu command line options seems minor compared
to all the profile and provisioning work that has to happen for other
device types.
