To convert between a kvm facing interface to an internal interface? I don't think they're necessary. The internal layout is visible from the KVM code. Just either spawn the class straight from the kvm file or if you consider that ugly, pass the values of that struct that you need as function parameters to a function in cpu-models.c.
