6.2.3. Cloning Virtual Machines from Existing Templates
You can clone a virtual machine from an existing template (either created by you, or one that came with the system). A template is a base virtual machine that is set with a unique configuration and settings. A virtual machine that is cloned from a particular template acquires the configurations and settings of the template. A virtual machine that has been provisioned as a clone includes a complete copy of the template's hard disk image, removing the requirement that the virtual machine stay in the same data domain as the template.
