Hrm. Could we make this the non-default for the time being with a simple
-machine option to switch it to the default? When enough kernels are aware of
the switch, we could then make it the default.
The best case would be if we could determine what type of kernel (default to
virtio-console vs runtime detect) we run before we spawn the VM, so we could
spawn it with the respective default and keep all kernels working...
