Single GUP Passthrough Config

This is my personal config, for a tutorial, you can read this.

Setup Libvirt

/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="... amd_iommu=on video=efifb:off iommu=pt ..."

/etc/libvirt/libvirtd.conf
`unix_sock_group = "libvirt"`
`unix_sock_rw_perms = "0770"`

/etc/libvirt/qemu.conf
`... user = "mageas" group = "wheel" ...`

Virt Hardware

Remove
`Display spice`
`Channel spice`
`Video QXL`
`Sound ich*`
`Serial 1`

Display Spice is important to be deleted (Delete all the references of spice in the XML).

Add PCI
`0000:04:00:0` NVMe
`0000:0c:00:0` RX 6900 XT
`0000:0c:00:1` RX 6900 XT
`0000:0C:00:4` Audio Controller
`0000:05:00:0` USB Controller

Add USB
Logitech G PRO
PnP Audio Device
Microdia Keyboard

Add TPM:

Type: Emulated
Model: CRB
Version: 2.0

Config Libvirt Hooks
