VAAPI in a VM

[MaxIO]

Hi, everybody.

I didn't find any information in the forum or on Google:
I'm looking to run Intel VAAPI in a VM.
I can only see /dev/dri/renderD128 from the VM when I set "virtio" on display graphics, but vainfo and ffmpeg can't use the device.

Do you have any idea?

Thank you very much.

vaapi is an API for video acceleration tasks, which requires driver & hardware (or virtual hardware) support. The only way for this to be useful is if you use GPU passthrough or a virtual GPU that supports it. It's possible that virtio-gpu will support this, but that part is still a work in progress and the required settings not exposed via our API.
