That's pretty cool!

Just one question: why not always use boxed configuration?  It should 
not make the instance_config types any larger, and it avoids unwieldy 
argument lists.

Also, for the obligatory bikeshedding remark, do you have any other 
plans or ideas for the colon-separated auto generated typenames?  Having 
both the "namespace" (qom) and the more specific use (config) before the 
classname is a bit weird, compared to the existing structs like 
RngRandomProperties.  Especially if boxed config is more used (or 
becomes the only possibility), it might be that qom:class-name:config, 
or even just class-name:config, make for nicer code in the object 
implementation.
