# 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 appear on your console as you type, it means that the device has been correctly identified, and that you can <kbd>Ctrl+Z</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>
|
||
```
