OpenNebula uses a method called contextualization to send information to the VM at boot time. Information is collected in the Template and is essential to configure the VM.

The VM template has a section called context where you can automate different configuration aspects.

Context section has 3 parts:

==='''''Configuration'''''===

[[File:Template-Configuration.png]]

This is the most basic context configuration, provided by OpenNebula, where you can:
* Enable '''SSH''' and '''Network''' contextualization
* Add '''SSH public keys'''. Keys will be added to USERNAME authorized_keys file or root in case USERNAME is not set.
* '''START_SCRIPT''' - Text of the script executed when the machine starts up. It can contain shebang in case it is not shell script. For example START_SCRIPT="yum upgrade".

==='''''Files'''''===

[[File:Template-Files.png]]

You can select files you want to include from the list and they will be automatically added in FILES_DS attribute.
Also you can define a space-separated list of scripts that will run at boot, using INIT_SCRIPTS attribute.

==='''''Custom Vars'''''===

[[File:Template-CustomVars.png]]

In this section you can setup a more advanced contextualization, the attributes available are:

*'''VARIABLE''' - Variables that store values related to this virtual machine or others . The name of the variable is arbitrary (in the example, we use hostname).

* '''SET_HOSTNAME''' - This parameter value will be the hostname of the VM.

* '''ETHx_MAC''' - Used to find the correct interface

* '''ETHx_IP''' - IPv4 address for the interface

* '''ETHx_NETWORK''' - Network address of the interface

* '''ETHx_MASK''' - Network mask

* '''ETHx_GATEWAY''' - Default IPv4 gateway for the interface

* '''ETHx_DNS''' - DNS for the network

* '''USERNAME''' - User to be created in the guest OS. If any password attribute is defined (see below) it will change this user (defaults to root).

* '''PASSWORD_BASE64''' - Password encoded in base64. To be set for the user USERNAME.

* '''PASSWORD''' - Password to be set for the user USERNAME. This parameter is not recommended, use PASSWORD_BASE64 instead.
