OS-DCF:diskConfig

The disk configuration value.

Valid values are:

• AUTO: The server is built with a single partition the size of the target flavor disk. The file system is automatically adjusted to fit the entire partition. This keeps things simple and automated. AUTO is valid only for images and servers with a single partition that use the EXT3 file system. This is the default setting for applicable Rackspace base images.

• MANUAL: The server is built using whatever partition scheme and file system is in the source image. If the target flavor disk is larger, the remaining disk space is left unpartitioned. This enables images to have non-EXT3 file systems, multiple partitions, and so on, and enables you to manage the disk configuration.

The result is :
