Mediated vs Passthrough of iGPU

[spetrillo]

Hello all,

I have an Intel iGPU that I would like to use in a Plex VM. It looks like I have two options. Has anyone dabbled here and which seems to be the most performant?

Thanks,
Steve

Which Intel CPU do you have? You can generally pass it through to a VM but you will lose the host's physical console unless you split the iGPU.

To support split iGPU so that you can still access the physical host console while passing it through to the VM you will need either:

• I915 VT-G if you have a 6th to 10th gen CPU
• I915 SR-IOV if you have 12th gen CPU and above

If you have 11th gen CPU then you are out of luck as it doesn't support either.

I run a 10th gen CPU and use VT-G to pass the iGPU through to an Ubuntu VM which has Plex running in a Docker container. It supports HW transcoding.
