This is a list of prerequisites you will be needing before starting with VFIO:
* 2 GPUs (iGPU/APU included)
* A \"ghost display\" dummy plug for your second graphic card.
* A \"ghost display\" dummy plug for your second graphic card (or having it hooked to a separate input on your monitor).
* If you are planning to use the inegrated GPU on your CPU, make sure your monitor is connected to it before continuing.
* Preferably a motherboard verified to work with IOMMU and with good IOMMU groups.
https://reddit.com/r/vfio is a good resource for this info.
