Congrats ! , LXC should be the most straight forward way ! intel_gpu_top will give you stats on the usage of the igpu on the host . e.g.

intel_gpu_top is part of intel-gpu-tools you can install via apt install intel-gpu-tools I do recall having to install linux-firmware on one guest machine I tried out , but nothing on the host . (I'm not sure sorry)

Just another thought , as a work around have you considered running plex in an LXC container ? and mapping /dev/dri ? (You'd need the igpu to be loaded by the host , so you'd need to undo any black listing of drivers (i915) etc . ) Iv'e tested this on a UHD630 , which works (and you can...

Hey guys @jimjam my gpu is a UHD630 apologies if i confused things , I had heard that gvt-g had been dropped for newer gpu’s but maybe made the assumption gvt-d should still work (or not made the distinction when i posted) I’m still interested in the thread, so good luck with finding a solution...

Do you have 2 GPU's or a vGPU also assigned ? not sure why yours is showing Card and renderD129 also . Have you tried running plex to check if it uses the gpu for HW transcode ?

look like you are making progress . if you do ls -l /dev/dri , do you see card0 and renderD128 in the directory . (This is what is required for Plex HW transcoding) Are you running Plex on the guest or in docker on the guest ? If if docker you will need to pass /dev/dri , i.e devices...

gvtd is quite different to gvtg If you are passing the whole igpu as in gvtd, you need to blacklist the drivers so the host does not use it , you should not be loading the drivers on the host, if the host grabs the igpu it will not be available to the guest vm. remove the i915 grub parameters (...

I have an issue on 15.15.19-2 passing UHD630 igpu to a VM . It works on 5.13.19-3 The following message floods the logs vfio-pci 0000:00:02.0: BAR 2: can't reserve [mem 0x80000000-0x8fffffff 64bit pref] I have added video=simplefb:off to my grub cmdline Any Ideas ?

Also trying to passthrough on 0x02 , is there anyway. The guest needs this for OpenGL

@fortechitsolutions This looks really useful thank you , 1 question , my manufacturer value and product value , have spaces in them . i.e Dell Inc. , Optiplex 7070 . Would I need to put single or double quotes around these ? i.e smbios1: uuid=<UUID>,manufacturer='Dell...
