From 55a1d80a41032d6133adec041c0096820beaa1b7 Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Tue, 1 Apr 2014 10:06:29 +0200 Subject: virtio-input: emulated devices [device] This patch adds the virtio-input-hid base class and virtio-{keyboard,mouse,tablet} subclasses building on the base class. They are hooked up to the qemu input core and deliver input events to the guest like all other hid devices (ps/2 kbd, usb tablet, ...). Using them is as simple as adding "-device virtio-tablet-device" to your command line, for use all transports except pci. virtio-pci support comes as separate patch, once virtio-pci got virtio 1.0 support.
