=== Part 1: Manage LVM GraphicallyManaging File System Size with Existing Hard Drive ===
[[Image:lvm1.png|thumb|500px|right|The '''system-config-lvm''' application allows the Linux system administrator to manage LVMs Graphically. Your LVM information for '''centos2''' VM should be similarly displayed.]]
===Part 2: Managing LVM Via Command Line & Adding Additional Virtual Hard Drives===
[[Image:add_virtual_disk.png|thumb|400px|right|You can add virtual hard disks for a VM by changing to the '''Details''' section for the VM (as opposed to ''console''), click '''Add Hardware''', fill information in the '''Add New Virtual Hardware''' dialog box and clicking '''Finish'''.]]
Let's say that you have run out of disk space on your '''centos3''' VM, and you need more space on the root file-system in order to host more web-pages, or to support a larger database. What are your options? Getting a replacement hard-drive would probably require re-installation of the operating system and/or backing up and restoring data on the old hard disk.
