+In this lab, you will create 3 virtual machines using a virtualization program called **KVM** that will run in your debhost system. These VMs will be used throughout the remainder of this course to learn how to administer them (installing software, managing services, networking, etc).
 
 While you are performing this lab, it is recommended to generally note the major differences in the different installation methods, and which method you prefer to use if you were a Linux system administrator in charge of installing many Linux distributions for an organization.

-- Installing additional Virtualisation Software on your **debhost** machine (**KVM**)

-At the end of Lab 2, your hypervisor (VirtualBox or VMWare) application will contain **4 virtual machines** (**debhost** in your hypervisor application, and **deb1, deb2, deb3 VMs** in your **KVM** application). You will now have the option to run one virtual machine at a time, or run all machines simultaneously to learn about networking (covered in later labs)
