Ah, yes, I see now.

I suppose what you're trying to determine is whether there is a viable 
use case for answering the question "given a single 'source partition' 
-- say, "my compute cloud region A" -- show me the usage of VCPU 
resources in my 'nova' compute hosts and my 'non-nova' compute hosts".

I'm just not sure there's a viable use case there.
