VGPU-KVM and CUDA Driver Version mismatch

Virtual GPU Forums General Discussion

When I install NVIDIA-Linux-x86_64-535.54.06-vgpu-kvm.run, cuda is not available anymore and it complains about driver version mismatch.

So which CUDA package I have to install with VGPU KVM driver?

In all you documentation there is no clear statement about that. Maybe you add that to documentation, after you found out.

Following: CUDA Compatibility :: NVIDIA Data Center GPU Driver Documentation you need CUDA 12.2

Guess you never tried that by yourself.

Tried 12.2 and 12.2.1

CUDA is always N/A with VGPU KVM driver.

What exactly are you going to achieve?
Why do you expect CUDA with the host driver? For a VM you should install the guest driver:
NVIDIA-Linux-x86_64-535.54.03-grid.run

This is only for KVM VMs with mdev device(s).

Yes this works as expected.

But I want to run CUDA on host and in containers (lxc/docker) too.

And containers for sure use the kernel module from the host, so it is also impossible to use cuda in containers with the vgpu KVM driver.
