Measures reported by QVDDiskImageTest

A Disk Image (DI) is a qcow2 image that has been created as a virtual disk containing an installed operating system.

QVD uses DIs to serve groups of users that make use of a common set of applications. By using a single image to cater to a number of users, it becomes easier to administer desktop environments for all of your users. It also improves overall security, since a policy can be applied to each group of users.

In this way, if a group of users require a particular application, you can install it once and the change will apply to all of the users that share the same DI. Equally, you can remove an application from an entire group's desktop environment.

DIs can easily be duplicated, so that you can quickly create additional environments for different subsets of users. By copying a base image, you can edit the copy and provide additional applications or other customizations to a second set of users without having to repeat a full operating system installation.

This test reports the number of disk images that are available in the Shared Storage of the QVD Server Node.
