In QOM parlance Jan implemented this: abstract class Object abstract class Device class APIC: { backend: link<APICBackend> } abstract class APICBackend class QEMU_APICBackend class KVM_APICBackendI don't fundamentally object to modeling it like this provided that it's modeled (and visible) through qdev and not done through a one-off infrastructure.
There is no superclass of DeviceState, hence doing it through qdev would mean introducing a new bus type and so on. This would be a superb example of a useless bus that can disappear with QOM, but I don't see why we should take the pain to add it in the first place. :)
We sure can revisit this when the subclassing and interface infrastructures of QOM are merged.
