PCI Passthrough (Proxmox VE wiki) — by Proxmox Server Solutions (Proxmox VE wiki)

advancedpageLink only (©)

A collection of checks, examples and known issues for passing PCI(e) devices to VMs, KVM only. It tells you to confirm IOMMU and interrupt remapping in dmesg, check IOMMU groups, blacklist host GPU drivers and consider a vBIOS romfile; the ACS override is described as a last resort with risks. A VM with a passed-through device cannot be live migrated.

Quick steps

Check IOMMU: dmesg | grep -e DMAR -e IOMMU
Check each device sits in its own IOMMU group
Blacklist host GPU drivers and reboot

Paraphrased from the source. Menus can differ by version, so check the original for full details.
