In that case, what is holding us from setting
cannot_instantiate_with_device_add_yet on TYPE_X86_CPU? I don't think we
can recommend using "-device" for CPUs just yet, but we would need to
allow it in case object-add doesn't work.
(But I liked the fact that object-add worked and (it looks like) it
didn't run realize(). All libvirt needs is to be able to create the
object and get instance_init() run, no need for realize() to run.)
I still need to read the reasoning behind the object-add changes. But is
there some chance we could allow object-add to work for TYPE_X86_CPU
subclasses, to avoid the device_add/cannot_instantiate_with_device_add_yet issues?
