iso2class Reference - Overview

The iso2class utility makes it easy to create new Operating System distros for CA 3Tera AppLogic appliances. The iso2class utility is used to create a singleton class using an Operating System installed from an ISO image. iso2class creates and starts an application which is used to install an operating system from an ISO image onto a volume. 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 Operating System install. The end result is a singleton with a single volume which contains the installed Operating System. This singleton can be moved into a catalog and be used as the basis for creating new appliance classes.

Important!

• See the Operating System Support Limitations topic in the Appliance Developer Guide for important information about the operating systems that are supported in CA 3Tera AppLogic.
• iso2class has only been tested with very few Operating systems and originally was not made for general Operating System usage. CA is working to make iso2class more generic to work with a wide variety of Operating systems.
• iso2class requires that the servers in the grid contain either Intel VT or AMD-V for hardware virtualization support (HVM). If HVM is not available on the grid, iso2class cannot be used.
