+### GPU Passthrough
+
+**As prerequisite** you should make sure the onboard graphics is still enabled and is the primary display.
+
+I follow the suggestions from [proxmox passthrough guide][proxmox-pci-passthrough]:
+
+First you want to blacklist GPU drivers to prevent the host from loading the GPU (we want to use in the VM :D )
+
+``` bash
+echo "blacklist amdgpu" >> /etc/modprobe.d/blacklist.conf
+echo "blacklist radeon" >> /etc/modprobe.d/blacklist.conf
+
+echo "blacklist nouveau" >> /etc/modprobe.d/blacklist.conf 
+echo "blacklist nvidia*" >> /etc/modprobe.d/blacklist.conf
+
+echo "blacklist i915" >> /etc/modprobe.d/blacklist.conf
+```
+
+After setting this you have to update the `ramfs` and reboot the system.
+
+``` bash
+update-initramfs -u -k all
+```
+
+Find Vendor and Devide ID to use for the VM Device (vfio)
+
+``` shell
+echo "options vfio-pci ids=10de:1ff0 disable_vga=1" > /etc/modprobe.d/vfio.conf
+```
+
+Reboot and add raw device (select map all functions)
+
+
+``` shell
+hostpci0: 0000:01:00,pcie=1
+```
