# Input devices
Input devices such as keyboards and mice are a must to directly interact with a virtual machine. There are multiple ways to share an input device with your virtual machine.
## Summary
* *to-be done. Add table here*.
## Methods
### Evdev
Event devices (evdev) is a generic input event interface available in the [Linux](https://www.kernel.org/doc/Documentation/input/input.txt) and FreeBDS kernels.
* Identify available input devices under `/dev/input/by-path/` or `/dev/input/by-id/` and look for devices that contains the string *event* in their name.
```
ls /dev/input/*
```
```
/dev/input/by-path:
pci-0000:07:00.0-event-mouse
pci-0000:09:00.0-mouse
pci-0000:07:00.0-mouse platform-i8042-serio-0-event-kbd
pci-0000:08:00.0-event-kbd platform-i8042-serio-1-event-mouse
pci-0000:09:00.0-event-mouse platform-i8042-serio-1-mouse
```
* Check if it's the correct device using the following command and typing or clicking on your device
```
sudo cat /dev/input/by-path/pci-0000:08:00.0-event-kbd
```
* If gibberish symbols should appear on your console as you type, it means that the device has been correctly identified, and that you can <kbd>Ctrl+Y</kbd>

<EFBFBD><EFBFBD>b<EFBFBD>y
<EFBFBD><EFBFBD>b<EFBFBD>y
```
Edit the virtual machine's definition and replace `MOUSE_NAME` and `KEYBOARD_NAME` with the previously identified devices.
```
<input type="evdev">
<source dev="/dev/input/by-path/MOUSE_NAME"/>
</input>
<input type="evdev">
<source dev="/dev/input/by-path/KEYBOARD_NAME" grab="all" repeat="on"/>
</input>
```
