GPU Passthrough to Docker/VMs

[tsaG]

Hi,

I am quite new at this topic (coming from a Synology NAS). I would like to run several Dockers and VMs on Server (currently assembled the hardware and downloading Trueness Scale). By browsing through, I read that you need more than 1 GPU to use the Passthrough, is this correct?

I plan to use Jellyfin and BlueIris which heavily relies on the Quicksync feature of the Intel GPU. I do not want to use an additional GPU as unnecessarily it increases Power draw and I do not have any spare PCI-E Slots (NIC and SAS controller).

Is it correct that this would not be possible in the current TrueNas version and configuration of my server?

Thanks!

Yes, quicksync can be supported.

Beginner sense check, Plex CPU usage in TrueNAS Scale

I recently retired my old PC and turned it into a NAS (TrueNAS-SCALE-22.02.0.1). I know it's not an ideal setup (see signature) but it should be ok for plex and nextcloud. I had some huge 4k mkv video files that needed converting in plex. My CPU ran at 100% when converting, is this normal? See...

My guess is its easier to share the GPU if all apps are containers.. not mixed VMs and container. Other users may have experience with this.

But then I have to pass through the GPU, correct? And as I understood, for this you would need a second GPU (?).

My understanding is that its working with upto 5 apps.

SOLVED - Intel GPU Plugin

Is it possible to set the -shared-dev-num mentioned in https://intel.github.io/intel-device-plugins-for-kubernetes/cmd/gpu_plugin/README.html#configuration-options? I'd like to give 2 apps access to the GPU for transcoding and this document from Intel makes it sound like that is possible, but I...

Yes, quicksync can be used by 5 apps at the same time. Nvidia on the other hand only on 1. (Upstream limitation from nvidia-device-plugin).

But, BlueIris is a windows app, and there isn't any (good) container for it. (If there is any please let me know, I need it lol).


With nvidia, you can't use it with apps AND vms at the same time. And any change between those two, will probably require a reboot.
I have no idea if this is the case with quicksync as well.
