Click to enlarge

The Image Management page contains a list of all available images in Moab. Here, you can create and manage your images (which map to actual xCat image files) so that you can make them available to users through service templates. On this page, you can do the following:

Search for images (see Searching, sorting, and filtering images).
View an image's details (see Viewing image details).
Create a new image (see Creating a new image).
Modify an existing image (see Modifying existing images).
Delete images you no longer need (see Deleting an image).

Search bar (contains)

Lets you specify a term to search in the field (for example, a term that would appear in an image Type or OS Type). For more information, see Searching, sorting, and filtering images.

You should not use the ampersand (&) character in your search.

Search filter drop-down

Lets you narrow your search to a specific field (one of Name, Type, or OS Type).

Filter by

Displays the filters applied to the images that appear in the list.

When you search on a specific field, the field value you selected is noted at the top of the Filter by section. For example, if you search by Type and enter "full_clone," the following appears:

To remove the filter on individual selected field values, click the remove icon () next to the filter you want to remove. To remove all filters so that all images appear in the list, choose Clear all filters.

Tip: To save a set of filters and specific sorting order for easy reuse, bookmark the Image Management page in your browser once you finish creating your filters.

List of available images

Displays a summary of all the images that exist in Moab. The following fields are displayed:

Field	Description
Name	Name of the image.
Type	One of the following: Stateful — Stateful images are deployed with a distribution-specific installation mechanism (for example, Anaconda or Kickstart for RHEL, WIM or WinPE for Windows Server, AutoYAST for SLES, etc.). Stateless — Stateless images are diskless images that boot from a network. When the machine boots, it downloads a compressed root image and expands it into memory; the machine continues booting from the contents of the image. Stateless images will not allow for changes made to the machine's main filesystem to persist across reboots. Statelite — A statelite image boots with a layered filesystem consisting of a shared read-only portion and a guest-specific read-write portion. These two portions are combined using a union filesystem. Linked Clone — A linked clone image is a single disk image that serves as the basis for cloning. When the new machine is created, disks are made that are read-write layers on top of the original (rather than copies from the original disk). In this way, part of the disk presented to the guest is shared between all clones of the image, and part is individual to each clone. Full Clone — A full clone image makes a full copy of the entire disk corresponding to the base image.
OS Type	The type of operating system
