As part of the Region B scenario implementation you create two customization specifications for use on the virtual machines you deploy from vRealize Automation. One specification is for a Linux guest operating system and one is for a Windows guest operating system. When you apply a specification to a guest operating system during virtual machine cloning or deployment, you prevent conflicts that might result if you deploy virtual machines with identical settings, such as duplicate computer names.

About this task

You later use the customization specifications when you create blueprints for use with vRealize Automation.
