===Part 2: Managing LVM Via Command Line & Adding Virtual Hard Drives===
[[Image:add_virtual_disk.png|thumb|500px400px|right|The You can add virtual hard disks for a VM by changing to the '''system-config-lvmDetails''' application allows section for the Linux administrator VM (as opposed to manage LVMs Graphically''console''), click '''Add Hardware''', fill information in the '''Add New Virtual Hardware''' dialog box and clicking '''Finish'''.]]
