Makes sense.

Well, I guess we could say Xen supports some physical partitioning 
concepts and for those resource types the pools will behave a little 
differently. IIRC, RASD has some type parameter for specifying whether 
the resource is pass-thru, virtualized, etc. And the virtual device can 
have a HostedDependency relationship with the physical device in the 
pass-thru case. What is unclear is existing modeling (and 
implementation) for such resources.
