VM Image is the new and improved image entity and replaces OS Images. It includes the OS disk, and adds data disks. Capture a VM (running or shut down) to create a VM Image. The underlying operating system may be generalized (for example, sys prep has been run for Windows or `waagent –deprovision’ executed for Linux - like an OS Image today), or specialized (where the provisioning information remains intact). Once captured, use a VM Image to deploy new VMs. Think of the generalized VM Image as a model you can use to use to stamp out similar VMs, and the specialized VM Image as a snapshot of the disks used to deploy a VM to a known good point in time.
