Can we get rid of the kernel command line hacking please?
The virtio-mmio devices should be discoverable somehow.
Device tree (as suggested by paolo) would work.
Custom acpi device (simliar to fw_cfg) is another option.
I'd tend to pick acpi, I wouldn't be surprised if we'll
need acpi anyway at some point.
Maybe even do both, then switch at runtime depending on -no-acpi
(simliar to arm/aarch64).
cheers,
Gerd
