Once installed, the extensions are placed in:
- _The power template folder for MAAS_: this is usually /etc/maas/templates/power.
- _The VBox_extensions folder in the MAAS default user_: this is usually maas, therefore some scripts are placed in /home/maas/VBox_extensions or /var/lib/maas/VBox_extensions.
- _The Vbox_host_extensions folder in the VirtualBox default user_: this is usually a standard user, for example IvanZoratti, therefore some scripts are placed in OS X in /Users/IvanZoratti/Vbox_host_extensions and in Ubuntu in /home/IvanZoratti/Vbox_host_extensions.

Each request (a Power ON request) follows this flow:
1. The request is activated by an admn action, for example "Commission Node"
2. MAAS calls the script generated by a power template, in this case "/etc/maas/templates/power/ether_wake.template"
3. The power template calls a script in the VBox_extension folder, in this case "power_on"
4. The power script checks the incoming request and sends a request to all the available VirtualBox hosts machines via SSH. The request calls a script in the VBox_host_extension folder, in this case "startvm"
