Hi,
>> If -hda has the semantics of "create an IDE device", then no, we can't change it. It doesn't however. IIRC on -M pseries -hda creates SCSI devices. On s390 -hda creates virtio devices. So if on -M q35 -hda would create if=ahci, I don't see how that breaks the CLI.

That will happen _anyway_. No doubt there will be configurations which
work with -M pc and break with -M q35.
cheers,
Gerd
