How to Enable IOMMU (VT-d / AMD-Vi) in Your BIOS and Proxmox VE for PCI Passthrough
IOMMU is the wall that makes GPU and NIC passthrough safe, and most beginners hit a dead end because the fix spans two places at once. Here's how to enable VT-d or AMD-Vi in BIOS, edit the right Proxmox VE bootloader file, and verify it actually turned on.
How to Set Up GPU Passthrough in Proxmox VE: A Beginner's Step-by-Step Guide
Give a virtual machine direct control of a real graphics card. This step-by-step guide covers IOMMU, VFIO, and attaching a GPU to a VM for Plex transcoding or gaming.
How to Pass Through an NVMe SSD to a VM in Proxmox VE (PCIe and Raw Disk Methods)
Give a VM direct, low-overhead access to a physical NVMe drive using PCIe (VFIO) passthrough or raw disk passthrough in Proxmox VE, including IOMMU setup, driver binding, and the hardware quirks that trip people up.
Diagnosing GPU Passthrough Failures on Proxmox VE 9.x: IOMMU Groups, VFIO Binding, and Reset Quirks
GPU passthrough breaks in a handful of predictable ways: driver race conditions at boot, messy IOMMU groups, GPUs that won't reset cleanly, and firmware unity-map restrictions on newer hardware. Here's how to diagnose and fix each one on Proxmox VE 9.x.
