Remote Gaming - GPU Passtrough guide with Proxmox


This tutorial is working for my config: a NVIDIA 3060TI, an AMD 5600x, Proxmox 7 and the the 5.13 kernel version.

If you need a Windows 11 VM. Check this guide.

Ensure that you have RDP or any other remote control software installed, because you won't be able to use VNC after using your GPU as your primary card.

Check your kernel version because most of the guides are deprecated by now.


Edit /etc/default/grub. Change this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet amd_iommu=on video=vesafb:off video=efifb:off"

Run update-grub:


Run reboot:


Edit /etc/modules/:


Run reboot:


In /etc/pve/qemu-server/XXX.conf (The VM id of your machine)

Replace the CPU line by this one:

cpu: host,hidden=1,flags=+pci

Here is my config if you want to have a look:

agent: 1
bios: ovmf
boot: order=virtio0;net0;ide2;ide0
cores: 8
cpu: host,hidden=1,flags=+pcid
efidisk0: ssd:vm-100-disk-0,efitype=4m,pre-enrolled-keys=1,size=4M
hostpci0: 0000:2d:00,pcie=1,x-vga=1
ide0: local:iso/virtio-win.iso,media=cdrom,size=519172K
ide2: local:iso/Win11_English_x64v1.iso,media=cdrom,size=5434622K
machine: pc-q35-6.1
memory: 16384
meta: creation-qemu=6.1.0,ctime=1654853116
name: backupw11
net0: virtio=16:DB:69:5D:5F:99,bridge=vmbr0,firewall=1
numa: 0
ostype: win11
scsihw: virtio-scsi-pci
smbios1: uuid=8e0ad09d-2a10-4368-9d2c-a599397f2083

tpmstate0: ssd:vm-100-disk-1,size=4M,version=v2.0
virtio0: ssd:vm-100-disk-2,size=128G
vmgenid: 03172900-0ee8-4f6d-acef-846cf7bf9810

blacklists the drivers:

echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf
echo "blacklist nvidia" >> /etc/modprobe.d/blacklist.conf

Create this file

echo "options vfio-pci ids=10de:1381,10de:0fbc" > /etc/modprobe.d/vfio.conf

where XXXX:XXXX is the device and vendor id of your gpu. Find them with lspci-nn.

This will output something like:

01:00.0 0300: 10de:1381 (rev a2)
01:00.1 0403: 10de:0fbc (rev a1)

Add you GPU card in proxmox to the vm by adding a pci device. Check everything (Primary GPU, All functions, Rom-bar, Pci express)

You can start your vm, connect it with the remote software that you have chosen, and install the nvidia drivers.

To make sure that your NVIDIA card is working, you can open Nvidia Control Panel, go to 'adjust image settings with preview' and check if the 3D rendering is working.
