• sudo pacman -S qemu-full virt-manager virt-viewer dnsmasq vde2 bridge-utils openbsd-netcat ebtables iptables

• Enable libvirtd

• sudo systemctl enable libvirtd

• Add you to the libvirt groups

• sudo usermod -aG libvirt $USER

• Restart your system

• sudo reboot now

• sudo virsh net-start default
• sudo virsh net-autostart default

• TPM Dependency

• sudo pacman -S swtpm
• Open virt-manager
• Open your VM
• Show virtual hardware details
• Add Hardware
• TPM

• Download Fedora available secure boot for linux

• auracle clone edk2-ovmf-fedora-bin

• If the secure boot is not auto enabled in your machine, go to xml and find for:

<os firmware="efi">
    <type arch="x86_64" machine="pc-q35-10.1">hvm</type>
    <firmware>
      <feature enabled="no" name="enrolled-keys"/> <!-- ADD THIS -->
      <feature enabled="yes" name="secure-boot"/> <!-- ADD THIS -->
    </firmware>
    <loader readonly="yes" secure="yes" type="pflash" format="raw">/usr/share/edk2/x64/OVMF_CODE.secboot.4m.fd</loader> <!-- ADD THIS -->
    <nvram template="/usr/share/edk2/x64/OVMF_VARS.4m.fd" templateFormat="raw" format="raw">/var/lib/libvirt/qemu/nvram/VIRTUALMACHINENAME!!!!!!_VARS.fd</nvram> <!-- ADD THIS -->
  </os>

• Don't forget to add the machine name in !

This methods creates a virtual GPU for the VM (slow performance also not support nvidia gpus)

• Open virt-manager
• Open your VM
• Show virtual hardware details
• Display Spice
• 
• Add Hardware
• Video
• Model = Virtio
• 
• If your VM uses Windows consider installing: VirtIO Drivers

This methods completly remove your gpu from the main host machine, and put it on VM Unfortunately to this works you will need a secondary gpu

• go to BIOS in your system
• enable virtualization
• enable IOMMU

Get the GPU id and GPU audio id, find than and save it, this is the gpu used for the main linux

• lspci -nn / NVIDIA simple: lspci -nn | grep "NVIDIA"

ID Example

[0030]: NVIDIA Corporation GP102 [GeForce GTX 1080 Ti] [10de:1b06] <-- this is the graphics id
[0030]: NVIDIA Corporation GP102 HDMI Audio Controller [10de:10ef] <-- this is the audio id

Enabling IOMMU in grub

• sudo vim /etc/default/grub

#AMD for AMD intel for intel..., change the id by the one you get from previous section
GRUB_CMDLINE_LINUX_DEFAULT="amd/intel_iommu=on vfio-pci.ids=graphicsId,audioId"

• sudo update-grub
• reboot

Now pickup the id from your integrated gpu or secondary gpu, this is the gpu used for virtual machine Add the ids in vfio

• sudo vim /etc/modprobe.d/vfio.conf

options vfio-pci ids=graphicsId,audioId
#This is not necessary but if you having problems try this, i dont know what this does but maybe your games outside the VM stop working
softdep nvidia pre: vfio-pci

Rebuilt init

• sudo mkinitcpio -p linux
• reboot

Open your virtual manager and check somethings

• chipset: Q35
• firmware: UEFI

Add new PCI Host device

Graphics

• 0000:001:... [NVIDIA]...

Audio

• 0000:002:... [NVIDIA]...
• have fun
