Snapshots are a great way to revert a machine back to a known configuration so you can start again, but remember, ANY changes you've made since the snaphot was taken will be lost. If you have created any scripts or files on your virtual machines you want to keep, make sure you put a copy of them in the shared folder (/media/sf_shared) as this belongs to the host machine and it's contents will be saved when the snapshot is restored. |

Machine Administration
The machines are started automatically via the machine_setup script when you create them for the first time but after that you are on your own to look after them. Here's a few pointers to administer your Rep Attack environment.
...
Shutdown
Log out of any terminal sessions, then on the console, as root (password is root) issue the shutdown -h now command. This should perform an orderly shutdown of the database and machine.

The Rep Attack machines have been configured with the Advanced Configuration and Power Interface (ACPI) daemon running. This daemon will perform an orderly shutdown using the shutdown -h now command if it detects the (virtual) power button is pressed. You can press the virtual power button by selecting the ACPI Shutdown from the Machine menu on the machines console window.

...
Startup
Start each virtual machine by highlighting the machine in the VirtualBox Console GUI and selecting the Start icon, or right click and select Start from the menu.
Restoring
...
So you've had a good play around with Rep Attack and you've tried all sorts of things but now you want to revert the machines back to a known state to start again? No worries! The machines are running from an "Initial" snapshot that was taken when the were started for the very first time. To restore them back to this point, follow these steps (for both machines):
- Shutdown the machine.
- In the VirtualBox Console window, highlight the machine and near the top right-hand corner of the VirtualBox Console window you will see a Snapshots button.
- Click on the Snapshots button to show the snaphot panel for that machine.
- Right click on the Initial snapshot and select the Restore Snapshot from the menu.
- You will be asked if you want to save the current state of the machine before restoring the Initial snapshot. That's up to you but I would recommend you uncheck the box as you probably don't want to keep all the stuff you've done then click the Restore button.
- It may take a few moments to undo all the changes you have made and put the machine back the way you found it.
