What do you mean by "vGPU type"? Are you referring to the multiple GPU 
types stuff where specific virt drivers know how to handle different 
vGPU vendor types? Or are you referring to a "non-nested VGPU inventory 
on the compute node provider" versus a "VGPU inventory on multiple child 
providers, each representing a different physical GPU (or physical GPU 
group in the case of Xen)"?
