QEMU vhost-user-input - Input emulation | ||
======================================= | ||
|
||
This document describes the setup and usage of the Virtio input device. | ||
The Virtio input device is a paravirtualized device for input events. | ||
|
||
Description | ||
----------- | ||
|
||
The vhost-user-input device implementation was designed to work with a daemon | ||
polling on input devices and passes input events to the guest. | ||
|
||
QEMU provides a backend implementation in contrib/vhost-user-input. | ||
|
||
Linux kernel support | ||
-------------------- | ||
|
||
Virtio input requires a guest Linux kernel built with the | ||
``CONFIG_VIRTIO_INPUT`` option. | ||
|
||
Examples | ||
-------- | ||
|
||
The backend daemon should be started first: | ||
|
||
:: | ||
|
||
host# vhost-user-input --socket-path=input.sock \ | ||
--evdev-path=/dev/input/event17 | ||
|
||
The QEMU invocation needs to create a chardev socket to communicate with the | ||
backend daemon and access the VirtIO queues with the guest over the | ||
:ref:`shared memory <shared_memory_object>`. | ||
|
||
:: | ||
|
||
host# qemu-system \ | ||
-chardev socket,path=/tmp/input.sock,id=mouse0 \ | ||
-device vhost-user-input-pci,chardev=mouse0 \ | ||
-m 4096 \ | ||
-object memory-backend-file,id=mem,size=4G,mem-path=/dev/shm,share=on \ | ||
-numa node,memdev=mem \ | ||
