We could keep the old inventory in the root RP for the previous vGPU type already supported in Queens and just add other inventories for other vGPU types now supported. That looks possibly the simpliest option as the virt driver knows that.<br>

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)"?<span class="gmail-HOEnZb"><font color="#888888"><br>
