Before we can complete this recipe, we have to get make sure we have the correct virtual machine running. Perform the following steps to do that:

1. Start VirtualBox, if it's not already started, and make sure to use the 64-bit Ubuntu virtual machine we created in Chapter 1, Setting up the Lab.
2. Once the virtual machine has started, run the Terminal application. Open a total of three Terminal tabs by pressing the Ctrl + Shift + T keys on your keyboard.
