pve.proxmox.com › wiki › Pci_passthroughIntroduction. PCI passthrough allows you to use a physical PCI device (graphics card, network card) inside a VM (KVM virtualization only). If you "PCI passthrough" a device, the device is not available to the host anymore. Note: PCI passthrough is an experimental feature in Proxmox VE.
