# Title: Proxmox LXC Hardware Passthrough & GPU Acceleration Setup
|
||||
# Description: Enables hardware passthrough for USB, Intel, NVIDIA, AMD GPUs inside privileged LXC containers.
|
||||
# Installs optional drivers/tools inside the container (vainfo, intel-gpu-tools, OpenCL, etc.)
|
||||
# Only supports PRIVILEGED containers for GPU passthrough.
|
||||
# License: MIT
|
||||
# Author: MickLesk (CanbiZ)
|
||||
# Repo: https://github.com/community-scripts/ProxmoxVED
|
||||
#
|
||||
# Usage: bash -c "$(wget -qLO - https://github.com/community-scripts/ProxmoxVED/raw/main/misc/hw-acceleration.sh)"
|
||||
#
|
||||
# Requires:
|
||||
# - Proxmox VE 8.1+
|
||||
# - Privileged LXC Containers
|
||||
# - GPU device available on host
|
||||
#
|
||||
# Features:
|
||||
# - USB Serial Passthrough
|
||||
# - Intel VAAPI passthrough + (optional) non-free drivers
|
||||
# - NVIDIA GPU passthrough for LXC (binds /dev/nvidia*)
|
||||
# - AMD GPU passthrough (experimental)
|
||||
# - Container driver installation via APT
|
||||
# - User group assignments (video/render)
|
||||
# - Interactive menu system via whiptail
