Creating and Uploading Glance Images
This section describes the process to prepare a special-purpose logical domain for use as the source of a “golden OS image.” This process is deliberately destructive to the domain's configuration. This process unconfigures system components such as network addresses, routes, host names, DNS entries, and so on.
After you install the simple-init tool and complete the following task, relevant portions of the domain's unique configuration are removed so that the golden image can be captured and re-deployed as an OpenStack guest domain. The simple-init tool starts automatically on the initial boot and configures the guest domain. simple-init uses metadata provided by OpenStack to configure the logical domain's host name, IP addresses, subnet masks, default gateways, DNS name servers and so on.
 | Caution - Do not use this process on live, active, or production systems. This process is destructive to OS configuration because it clears information such as IP addresses, routes, host names, and so on. After you perform this process on a guest domain, you cannot use that guest domain for general purposes. |
