iso2class utility

The iso2class utility creates a singleton class using an OS installed from an ISO image.

You do not need to create an appliance prior to running iso2class. The iso2class utility creates a singleton appliance and places it in the application specified by the app_name= parameter.

iso2class creates and starts an application, then installs an operating system on the ISO image to a volume on the application. This application is generated from a template and contains a singleton named iso2class. The boot volume of the singleton is an ISO image. A second volume on the singleton is the target for the OS install.

The result is a singleton with a single volume which contains the installed OS. This singleton can be moved into a catalog and be used as the basis for creating new appliance classes.

Creating new appliances for specific operating systems requires the use of ISO images (cd-rom/DVD). The ISO is used to install the OS inside of an appliance using the iso2class utility. The ISO may be stored on the grid impex volume or a global volume, or from a remote website using HTTP.

You can access the ISO image for OS install from:

• Stored on the impex volume of the grid, if the ISO image was either copied to the impex volume by the maintainer or imported from a remote server
• Stored as a global volume on the grid if the ISO image was imported from a remote server
• Imported from a URL

For the additional information, including the iso2class commands, usage and operating system specific considerations, refer to the iso2class: Appliance Distro Creation Utility section of the Command Line Reference.

When you use the "3t util iso2class" if os= is not specified, a selection list of all supported Windows and Linux operating systems displays.
