# GPU Passthrough on Linux
|
||||
|
||||
## Enable IOMMU
|
||||
|
||||
```bash
|
||||
sudo vim /etc/default/grub
|
||||
```
|
||||
|
||||
Add amd_iommu=on iommu=pt
|
||||
|
||||
`GRUB_CMDLINE_LINUX_DEFAULT="... amd_iommu=on iommu=pt"`
|
||||
|
||||
```bash
|
||||
sudo grub-mkconfig -o /boot/grub/grub.cfg
|
||||
sudo reboot
|
||||
```
|
||||
|
||||
Verify
|
||||
|
||||
```bash
|
||||
sudo dmesg | grep -i iommu
|
||||
```
|
||||
|
||||
## Find GPU IDs
|
||||
|
||||
```bash
|
||||
lspci -nn | grep -E "VGA|Audio"
|
||||
```
|
||||
|
||||
In my case, I get
|
||||
|
||||
- `10de:28a0`
|
||||
- `10de:22be`
|
||||
|
||||
## VFIO Module Options
|
||||
|
||||
```bash
|
||||
sudo vim /etc/modprobe.d/vfio.conf
|
||||
```
|
||||
|
||||
> ### Arch
|
||||
> ```bash
|
||||
> options vfio-pci ids=10de:28a0,10de:22be
|
||||
> ```
|
||||
|
||||
> ### Fedora
|
||||
> ```bash
|
||||
> options vfio-pci ids=10de:28a0,10de:22be disable_vga=1
|
||||
> softdep nvidia pre: vfio-pci
|
||||
> softdep nouveau pre: vfio-pci
|
||||
> ```
|
||||
|
||||
## Blacklist GPU
|
||||
|
||||
```bash
|
||||
sudo vim /etc/modprobe.d/blacklist-gpu.conf
|
||||
```
|
||||
|
||||
> ### Arch
|
||||
> ```
|
||||
> blacklist nouveau
|
||||
> blacklist nvidia
|
||||
> blacklist nvidia_drm
|
||||
> blacklist nvidia_modeset
|
||||
> ```
|
||||
|
||||
> ### Fedora
|
||||
> ```
|
||||
> blacklist nouveau
|
||||
> blacklist nvidia
|
||||
> blacklist nvidia_drm
|
||||
> blacklist nvidia_modeset
|
||||
> blacklist nvidia_uvm
|
||||
> blacklist rivafb
|
||||
> blacklist nvidiafb
|
||||
> blacklist snd_hda_intel
|
||||
> ```
|
||||
|
||||
## Load VFIO
|
||||
|
||||
> ### Arch
|
||||
> ```bash
|
||||
> sudo vim /etc/mkinitcpio.conf
|
||||
> ```
|
||||
> ```
|
||||
> MODULES=(vfio vfio_iommu_type1 vfio_pci)
|
||||
> ```
|
||||
> ```
|
||||
> sudo mkinitcpio -P
|
||||
> sudo reboot
|
||||
> ```
|
||||
|
||||
> ### Fedora
|
||||
> ```bash
|
||||
> sudo vim /etc/dracut.conf.d/10-vfio.conf
|
||||
> ```
|
||||
> ```
|
||||
> force_drivers+=" vfio vfio_iommu_type1 vfio_pci "
|
||||
> ```
|
||||
> ```bash
|
||||
> sudo dracut -f
|
||||
> ```
|
||||
> ```bash
|
||||

|
||||

|
||||
|
||||
### Confirm Kernel Driver
|
||||
|
||||
```bash
|
||||
lspci -nnk -d 10de:28a0
|
||||
```
|
||||
|
||||
```bash
|
||||
lspci -nnk -d 10de:22be
|
||||
```
|
||||
|
||||
## Install Virtualization Stack
|
||||
|
||||
> ### Arch
|
||||
> ```bash
|
||||
> sudo pacman -S --needed virt-manager qemu-full libvirt dnsmasq ovmf swtpm
|
||||
> ```
|
||||
|
||||
> ### Fedora
|
||||
> ```bash
|
||||
> sudo dnf install @virtualization virt-manager qemu-kvm libvirt-daemon-config-network libvirt-daemon-kvm bridge-utils edk2-ovmf swtpm
|
||||
> ```
|
||||
|
||||
## User Groups and Permissions
|
||||
|
||||
> ### Arch
|
||||
> ```bash
|
||||
> sudo usermod -aG libvirt,kvm,input,render,libvirt-qemu $USER
|
||||
> ```
|
||||
|
||||
> ### Fedora
|
||||
> ```bash
|
||||
> sudo usermod -aG libvirt,kvm,input,render $USER
|
||||
> ```
|
||||
|
||||
Reboot the system.
|
||||
|
||||
And now verify:
|
||||
|
||||
```bash
|
||||
virsh list --all
|
||||
```
|
||||
|
||||
If it doesn't error, you're good.
|
||||
|
||||
# Create the VM
|
||||
|
||||
Start virt-manager
|
||||
|
||||
```bash
|
||||
virt-manager
|
||||
```
|
||||
|
||||
When creating VM:
|
||||
|
||||
- Local ISO
|
||||
- Windows 11 ISO
|
||||
- Firmware: UEFI (OVMF)
|
||||
- Chipset: Q35
|
||||
- TPM: emulated
|
||||
|
||||
Before you start the VM:
|
||||
|
||||
```bash
|
||||
sudo vim /etc/default/ufw
|
||||
```
|
||||
|
||||
Find `DEFAULT_FORWARD_POLICY="DROP"` and change it to `DEFAULT_FORWARD_POLICY="ACCEPT"`
|
||||
|
||||
Now boot the VM.
|
||||
|
||||
## Network Issues
|
||||
|
||||
If the network is being wonky, or if you want to bypass updates... Shift-F10
|
||||
|
||||
```
|
||||
OOBE\BYPASSNRO
|
||||
```
|
||||
|
||||
Now add the PCI devices in virt-manager.
|
||||
|
||||
```bash
|
||||
yay -S looking-glass
|
||||
```
|
||||
|
||||
On Windows, download the host from https://looking-glass.io/downloads
|
||||
|
||||
```bash
|
||||
sudo virsh edit win11
|
||||
```
|
||||
|
||||
Inside `<devices>`
|
||||
|
||||
```xml
|
||||
<shmem name="looking-glass">
|
||||
<model type="ivshmem-plain"/>
|
||||
<size unit="M">128</size>
|
||||
</shmem>
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo vim /etc/tmpfiles.d/10-looking-glass.conf
|
||||
```
|
||||
|
||||
```
|
||||
# Type Path Mode UID GID Age Argument
|
||||
f /dev/shm/looking-glass 0660 YOURUSER kvm -
|
||||
```
|
||||
|
||||
```bash
|
||||
sudo rm -f /dev/shm/looking-glass
|
||||
```
|
||||
```bash
|
||||
sudo systemd-tmpfiles --create /etc/tmpfiles.d/10-looking-glass.conf
|
||||
```
|
||||
```bash
|
||||
ls -l /dev/shm/looking-glass
|
||||
```
|
||||
|
||||
Should be owned by my user.
|
||||
|
||||
## Install Virtual Display Driver on Windows.
|
||||
|
||||
## Configure Looking Glass
|
||||
|
||||
```bash
|
||||
vim ~/.looking-glass-client.ini

||||
fullscreen=yes
|
||||
size=2880x18900
|
||||
dontUpscale=yes

```
|
||||
|
||||
```bash
|
||||
env -u WAYLAND_DISPLAY looking-glass-client
|
||||
```
|
||||
|
||||
## Audio
|
||||
|
||||
Edit XML. Inside `<devices>`
|
||||
|
||||
```xml
|
||||
<sound model="ich9"/>
|
||||
<audio id="1" type="spice"/>
|
||||
```
|
||||
|
||||
## Clipboard
|
||||
|
||||
Edit XML. Inside `<devices>`
|
||||
|
||||
```xml
|
||||
<channel type="spicevmc">
|
||||
<target type="virtio" name="com.redhat.spice.0"/>
|
||||
</channel>
|
||||
```
|
||||
|
||||
## File Sharing
|
||||
|
||||
Enable Memory → Shared in the virt-manager
|
||||
|
||||
```bash
|
||||
sudo pacman -S virtiofsd
|
||||
```
|
||||
|
||||
```bash
|
||||
mkdir -p ~/vmshare
|
||||
```
|
||||
|
||||
Edit XML. Inside `<devices>`
|
||||
|
||||
```xml
|
||||
<filesystem type="mount" accessmode="passthrough">
|
||||
<driver type="virtiofs"/>
|
||||
<source dir="/home/USERNAME/vmshare"/>
|
||||
<target dir="vmshare"/>
|
||||
</filesystem>
|
||||
```
|
||||
|
||||
Install virtio-guest-tools. Hey guess what, this also seems to make the windows key work.
|
||||
|
||||
Also install winfsp
