Red Hat Training

A Red Hat training course is available for Red Hat CloudForms

Chapter 13. Instances and Images

Images are the static templates containing the software configuration from which you provision a running Instance - a virtual machine, with which you can interact - on your cloud provider.

The Instance and Images containers, combined with the ability to analyze information inside each instance or image, provides in-depth information across the cloud environment. This rich set of information enables Red Hat CloudForms users to improve problem resolution times and effectively manage instances and images in their cloud environment.

The Instances and Images pages display all instances and images the server discovered from your cloud providers. The taskbar on each page is a menu driven set of buttons that provide access to functions related to instances and images.
