GPU Pass-through On Linux/Virt-Manager like qemu/kvm09.02.24

# Check if you have an extra GPU available with
```console
neofetch
```

# If you have at least 2 GPUs, then find out the IDs you like to use
with the command below
```console
lspci -nn
```
## write down the IDs, in my case I took the IDs from my build in graphic card and its audio
```text
00:02.0 Display controller [0380]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor Integrated Graphics Controller [8086:0412] (rev 06)
00:03.0 Audio device [0403]: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor HD Audio Controller [8086:0c0c] (rev 06)

```

# After you found your ids, add them to the grub file /etc/default/grub 
with "intel_iommu=on vfio-pci.ids=8086:0412,8086:0c0c"
The line will look like:
```txt 
GRUB_CMDLINE_LINUX_DEFAULT="intel_iommu=on vfio-pci.ids=8086:0412,8086:0c0c"
```

# rebuild grub and reboot
```console
sudo grub-mkconfig -o /boot/grub/grub.cfg
```
#find out how is using your device
```console
lspci -k
```
it shows that my card was in use by i915,
so I have to overwrite the preference below

# create the file /etc/modprobe.d/vfio.conf

```text
options vfio-pci ids=8086:0412,8086:0c0c
softdep  pre: vfio-pci
```
# update the kernel loading with one of 2 below commands(depends on your system) 
```console
sudo mkinitcpio -p linux
sudo update-initramfs -u
```

# reboot and add the hardware "PCI Host Device" in your QEMU manager
