What is
going to happen if you have more than one instance of the same
type of controller? In other words, I do not think that type is unique
to be the ID. To make it unique you also need the index which is also a
mandatory attribute.

Model is an optional attribute. So if I read this correctly dev->model
might be NULL and you create a new property with it. I am not sure what
libvirt is going to do about it.
