You can import an existing specification using the Customization Specification Manager, and use the specification to customize the guest operating system of a virtual machine.

Before you begin, you must have at least one customization specification saved as an xml file located on a file system accessible from the vSphere Web Client.


From the vSphere Web Client Home inventory page, select Policies and Profiles > Customization Specification Manager.


Click the Import specification from a file icon.


From the Open dialog, browse to the .xml to import and click Open.

The imported specification is added to the list of customization specifications.
