Here's how to set up a Windows 10 virtual machine in KVM with PCI passthrough. The VM will have access to an NVIDIA graphics card while the host machine (running Debian Buster) uses Intel integrated graphics. This is mostly for my own reference so I don't forget how I did it.

Hardware

Intel i5 (an old one) with integrated graphics: this will be used as the graphics card for the host machine running Debian Buster
NVIDIA Geforce 1070: this will be used as the graphics card for the Windows 10 VM

Step 1: Enable IOMMU

In order to do hardware passthrough with KVM at all, you need to enable the Intel Vt-d virtualization extensions. Edit /etc/default/grub and edit the GRUB_CMDLINE_LINUX_DEFAULT line so that it reads like:

	#!/bin/bash
	# Sample usage is as follows;
	# ./signapk myapp.apk debug.keystore android androiddebugkey
	#
	# param1, APK file: Calculator_debug.apk
	# param2, keystore location: ~/.android/debug.keystore
	# param3, key storepass: android
	# param4, key alias: androiddebugkey

	USER_HOME=$(eval echo ~${SUDO_USER})
