keep in mind that this plugin is soon to be not working anymore with future OS/Kernel updates. There is quite some work to be done.

 

In theory it should "just work" once the new Intel drivers are ready for production use, assuming the new drivers support your Intel GPU.

 

This is from Intel's announcement:

SR-IOV Platforms
================

Initially we plan to add SR-IOV functionality to the following SDV platforms
already supported by the Xe driver:

 - TGL (up to 7 VFs)
 - ADL (up to 7 VFs)
 - MTL (up to 7 VFs)
 - ATSM (up to 31 VFs)
 - PVC (up to 63 VFs)

Newer platforms will be supported later, but we hope that enabling will be
much faster, as majority of the driver changes are either platform agnostic
or are similar between earlier platforms (hence we start with SDVs).
 

 

 

Those platforms are Tiger Lake, Alder Lake, Meteor Lake, Arctic Sound M, and Ponte Vecchio respectively.

Just to confirm, SR IOV doesn't make it possible to use the iGPU with Docker containers (example Plex for HW transcoding) and also multiple VMs passthrough, at the same time correct? We have to choose either one?

SR-IOV lets you split the iGPU up to seven ways. Either the host (for Docker) + 6 VMs, or 7 VMs if you don't use the GPU on the host.

No, the VFs are for virtual machines. So 7 VFs can be used on 7 VMs simultaneously.
