Help setting up a linux vm with passtrouth enabled gpu

Hi all,

I’m having some issues running a docker container (triton inference server) on a vm using the host gpu (passthrough)

My setup is the following:

Linux ubuntu 20.04
800 GB Disk
16 cores

Linux Ubuntu 20.04
48 GB Disk
8 Cores
Virualized using qemu

I believe the passthrouth is configured well since I can see the graphics card using lspci and nvidia-smi identifies it correctly.

I’ve installed the nvidia-docker2 and configured it as docker default runtime. I’ve also installed kernel headers and development packages and CUDA drivers 470.103.01-1.

When i run a container that uses gpu (such as triton inference server) the container freezes not only itself but also the whole VM (it is not possible to docker stop or docker rm it.

I’m not sure if I need a nvidia license server or if my graphics card is not compatible with gpu passthrough/iommu.

Any help is welcome. thanks!


You may need to configure your container to allow access and pass through the proper device files.
