LXC: pytorch with gpu/npu support (intel Core Ultra 5 125H)

[witje]

I want to use Pytorch/openVino to train some small neural networks.
Already done:

• PVE 9, intel core ulte 5 125H
• priviliged and unpriviliged LXC, Ubuntu 22 and 24 (strange behauviour in ubunte 24, no IP4 address received, IP6 works 'fine')
• in priviliged containers, i can use intel_gpu_top; in unpriviliged containers i cannot use intel_gpu_top
• with or without device passtrhough (/dev/dri/renderDx and /dev/dri/card0, or manual in de conf file adding the passtrough /dev/dri/xxx
• I installed intel drivers in the lxc

In best case
When i try in pytorch: torch.xpu.is_available() --> false
or in openVino: core.available_devices: --> [ INFO ] Available devices: Segmentation fault

Has anybody figured this out and could give me some usefull tips?
