Intel iGPU passthough

CJ

What are you using for display output on the host since you're passing the iGPU to the VM?

@CJ Im running server grade hardware that has remote lights out management with iKVM support. Otherwise yeah you would lose access to the display output.

@CJ

No output just need the Intel quick sync.

CJ

@xerxist Yes, QS for the VM but there are times when having a local display of the console comes in handy. That's why I haven't done mine.

@bullerwins said in Intel iGPU passthough:

@olivierlambert I tried but getting this error when turning on the VM

INTERNAL_ERROR(xenopsd internal error: (Failure
"Error from xenguesthelper: Populate on Demand and PCI Passthrough are mutually exclusive"))

Not sure what it means

EDIT: after googleing it seems that static and dynamic memory has to be the same:

@bullerwins thanks for this. I had to restore a VM from a backup and while it was down changed the dynamic value. This certainly saved me some time. I was positive it had to do with remapping the UID on the VM or something on the host side of it. anyways, thanks.

I followed this post and it worked for me.
One thing to note in my testing, if I had a monitor / HDMI dummy plug hooked up the transcoding worked reliably.
When I unplugged it I found activity would be present on the iGPU but the video in plex would play/pause constantly then eventually stop.

@scawtydont Thanks for keeping us posted. Dummy plug is still a thing it seems

I'm also trying to pass through my Intel iGPU to a VM, but running into issues. It does work on Debian, however not on Fedora Server which I'd like to use. I have tried changing to BIOS mode, even plugged in a dummy HDMI plug, but nothing helped. SELinux is disabled on Fedora to rule out any issues related to that. I even tried using XCP-NG Center which was suggested in an older post, but that didn't help either: https://xcp-ng.org/forum/topic/6211/intel-gpu-passthrough-question/3

I also posted this on the Fedora forum with further details: https://discussion.fedoraproject.org/t/intel-igpu-in-containers/176029

Are there any other things I could try to investigate this further?

@vhaelan Hello. What's the output of rpm -qa | grep intel-gpu-firmware ?
