+# 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>
+
+```
+��b����b����b�!��b���b�� ��b����b����b����b����b��fdsa��b�( ��b�(��b!��b��bR��bR��bW��bW��b�!��b�f��b4 ��b4��bV��bV��bX��bXdsa��b!:	!��b!:	��b>:	 ��b>:	��b�
+��b�
+��b�y
+��b�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>
+```
