With proper qdev support, you could select kvm device models based on -device so I think this option isn't all that useful.

qdev (mostly?) is about the guest interface; this is more about the host implementation, so akin to -drive file= and cache=.

What I'd like to see in the interim is a kvm specific machine type that's defaulted to if kvm is enabled. I think this would be useful not only for enabling things like in-kernel apic, but also for selecting a default cpu model.

We should make a distinction between guest-visible changes and accelerators like kvm-irqchip and vhost.
