But doesn't qemu allow for evdev passthrough? Well yes, but from my experience it's complete trash. It works for simple cases like a usb mouse or a keyboard. But anything else doesn't work properly.
This post shows a way to pass any input device (available in evdev) to a guest system. The devices will behave the same as they behave on the host machine. This method also allows switching between guest and host machine control with a simple keyboard shortcut (NOT IMPLEMENTED YET).

To find a event for a device you can cat the event files in /dev/input, /dev/input/by-path and /dev/input/by-id.

If you need to you can also switch the server and client roles around ("--server" and "--client"). But you'll also need to modify the ip addresses (probably 192.168.122.1 for the guest client and 0.0.0.0 for the host server).
