This guide covers setting up Ollama (Open Large Language Model) in a Proxmox LXC container with GPU passthrough and creating a simple web interface for easy interaction. Overview We’ll deploy Ollama in a resource-constrained LXC environment with: Intel UHD Graphics GPU acceleration llama3.2:1b model (~1.3GB) Lightweight Python web interface Auto-starting services Prerequisites Proxmox VE host Intel integrated graphics (UHD Graphics) At least 4GB RAM allocated to LXC 40GB+ storage for container Step 1: Container Setup Check Available GPU Resources First, verify GPU availability on the Proxmox host: ...

Problem Proxmox shows this warning message: WARNING: You have not turned on protection against thin pools running out of space. WARNING: Set activation/thin_pool_autoextend_threshold below 100 to trigger automatic extension of thin pools before they get full. This warning indicates that LVM thin pools are not configured to automatically extend when they approach capacity, which could lead to VMs running out of disk space unexpectedly. Solution Configure LVM to automatically extend thin pools before they become full. ...
