+
+## Blacklist GPU
+
+```bash

+> blacklist snd_hda_intel
+> ```
+
+## Load VFIO
+
+> ### Arch
+> ```bash
+> sudo vim /etc/mkinitcpio.conf
+> ```
+> ```
+> MODULES=(vfio vfio_iommu_type1 vfio_pci)
+> ```
+> ```
+> sudo mkinitcpio -P

+> ```
+> ```bash
+> sudo dracut -f
+> ```
+> ```bash
+> sudo reboot
+> ```
+
+### 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

+> ```
+
+> ### 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.

+# Windows VM Setup
+
+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">

+```
+```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
+```
+
+```ini
+[win]
+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
