Create vSphere image customization specifications to use with your vRealize Automation IaaS Servers and Proxy Agent deployments. The customization specification you create customizes the guest operating systems of the virtual machines that host the vRealize Automation IaaS Web Server and IaaS Manager Services.
About this task
Customization specifications are XML files that contain guest operating system settings for virtual machines. You create customization specifications with the Guest Customization wizard, and manage specifications using the Customization Specification Manager. vCenter Server saves the customized configuration parameters in the vCenter Server database. When you clone a virtual machine or deploy a virtual machine from a template, you can customize the guest operating system of the virtual machine to change properties such as the computer name, network settings, and license settings. When you apply an image customization specification to the 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.
