vhost-device-input

Synopsis

vhost-device-input --socket-path <SOCKET_PATH> --event-list <EVENT_LIST>

Description

This program is a vhost-user backend that emulates a VirtIO input event. It polls on a host's input event device (/dev/input/eventX) and passes the input event data to guests.

This program is tested with QEMU's vhost-user-input-pci. The implemenation is based on the vhost-user protocol and as such should be interoperable with other virtual machine managers. Please see below for working examples.

Options

    -h, --help
        Print help.

    -s, --socket-path <SOCKET_PATH>
        Location of vhost-user Unix domain sockets, this path will be suffixed with
        0,1,2..event_count-1.

    -e, --event-list <EVENT_LIST>
        Input event device list in the format: event_device1,event_device2,...
        Example: --event-list /dev/input/event14,/dev/input/event15

Examples

The daemon should be started first:

host# vhost-device-input --socket-path /some/path/input.sock    \
      --event-list /dev/input/event14,/dev/input/event15

Note that from the above command the socket path "/some/path/input.sock0" and "/some/path/input.sock1" will be created for input events "event14" and "event15" respectively. This in turn needs to be communicated as chardev sockets to QEMU in order for the backend daemon and access the Virtio queues with the guest over the shared memory.

host# qemu-system -M virt                                                   \
      -object memory-backend-file,id=mem,size=4G,mem-path=/dev/shm,share=on \
      -chardev socket,path=/some/path/input.sock0,id=kbd0                   \
      -device vhost-user-input-pci,chardev=kdb0                             \
      -chardev socket,path=/some/path/input.sock1,id=mouse0                 \
      -device vhost-user-input-pci,chardev=mouse0                           \
      -numa node,memdev=mem                                                 \
      ...
