proxmox-pci-passthrough

What problem does it solve?

This Skill unit streamlines the process of pass-through PCI devices to VMs on Proxmox VE, overcoming hardware and software constraints for improved performance and functionality.

Core Features & Use Cases

• IOMMU and VFIO Setup: Configure the host and VM for IOMMU passthrough mode with VFIO support.
• Driver Binding: Pre-bind PCI devices to VFIO during system initialization.
• VM Configuration: Specify the passthrough PCI device in VM configurations for GPU, USB, or NVMe use.
• Wayland Scaling for 4K TV: Provide optimal UI scaling for 4K TV displays on GNOME Wayland.
• Caveats and Troubleshooting: Include best practices and mitigations for common issues in GPU and iGPU passthrough, display detection, and root configurations.
• Verification: Offers a detailed verification checklist post-installation for PCI device detection and binding, and VM display verification.
• References: Links to specific hardware setup details for iGPU passthrough on the HP ProDesk 600 G5 Mini.
• VM Requirements: Detailed setup steps and considerations for GPU and VM configurations including required firmware and driver setups.

Quick Start

Enable PCI passthrough for a GPU with Intel iGPU using qm set <VMID> -hostpci0 <PCI_ADDR>,pcie=1,x-vga=1
