OpenStack Images can take several forms, but generally an image consists of a static copy of a virtual machine with an operating system with some amount of storage. Each project starts out with a few base Linux and Windows images from which instances can be created. Images can also be created or uploaded to OpenStack, and then used to launch instances.

Creating an Image

Note: You should not take a snapshot of a file system that's mounted. You will lose all the info that's still in Linux's write cache. So if you want to take a snapshot of the root file system, the OS cannot be running.
