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:

Download the "virtual" type aarch64 ISO file from https://www.alpinelinux.org/downloads/ with wget
Execute sudo dd if=alpine.iso of=/dev/sda
On the Oracle Cloud panel, setup a console connection and connect to the serial console.
Execute sudo reboot
When Alpine is launched and you are logged in as root, execute these commands in the serial console:

Creating new/overwriting existing stubs & proxy configs

The motivation is: ssh to remote computer without port forwading, dynamic DNS and so on, the only thing needed is that the remote is connected to the Internet.

On remote get tmate, put it in /usr/local/bin (apt version as of 18.04LTS is too old):

curl -L https://github.com/tmate-io/tmate/releases/download/2.4.0/tmate-2.4.0-static-linux-amd64.tar.xz|tar xJv
sudo mv tmate-2.4.0-static-linux-amd/tmate /usr/local/bin
