iso2class Reference - Overview

The iso2class utility makes it easy to create new OS distros for CA 3Tera AppLogic appliances. The iso2class utility is used to create a singleton class using an OS 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 OS install. The end 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.

Important!

• See the OS 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 Onerating systems and originally was not made for general OS usage. CA is working to make iso2class more generic to work with a wide variety of Onerating 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.
