A template is a copy of a virtual machine for the purpose of reproducing the virtual machine. Virtual machines created from a template are identical to the model virtual machine from which the template was taken, eliminating the need to configure each one individually.
When creating a template, select a model virtual machine that is general enough for mass production. A virtual machine that is too specific to a particular user or group is not practical for use as a template.
Note
Before a Windows template is ready for application, you must first run
Sysprep (or a similar tool) to seal the virtual machine and remove "specific" personalization. Failure to do so will cause conflicts when running multiple virtual machines from an unsealed Windows template. In general, templates of Linux virtual machines do not require sealing.
