### Keyboard/Mouse Passthrough
Modify libvirt configuration of your VM. Change first line to:
< table >
< tr >
< th >
virsh edit win10
< / th >
< / tr >
< tr >
< td >
```xml
< domain type = 'kvm' xmlns:qemu = 'http://libvirt.org/schemas/domain/qemu/1.0' >
```
< / td >
< / tr >
< / table >
Find your keyboard and mouse devices in ** */dev/input/by-id***. You'd generally use the devices ending with ** *event-kbd*** and ** *event-mouse***. And the devices in your configuration right before closing `</domain>` tag. \
Replace ** *MOUSE_NAME*** and ** *KEYBOARD_NAME*** with your device id.
< table >
< tr >
< th >
virsh edit win10

### **Audio Passthrough**
VM's audio can be routed to the host. You need ** *Pulseaudio***. \
Modify the libvirt configuration of your VM.

### Video card driver virtualisation detection
Video Card drivers refuse to run in Virtual Machine, so you need to spoof Hyper-V Vendor ID.

```xml

Nvidia guest drivers also require hiding the KVM CPU leaf:
