+[Virtual Function I/O Mediated devices](https://www.kernel.org/doc/html/latest/driver-api/vfio-mediated-device.html) (vfio-mdev) allows a phyiscal GPU to be split into multiple virtual GPUs (vGPU). Such a vGPU can then be assigned to a virtual machine or a container.
 
 Contrary to paravirtualized GPUs (e.g. *virtio-gpu*), vGPUs can use the same driver as their parent GPU (e.g. a guest compatible with an Intel GPUs will be able to leverage an Intel-based vGPUs)
