Abstract
A system, program product, and method are provided for copying a virtual machine image. An image library comprising a plurality of system images is provided by a target data processing system. A source image selection is received at the target data processing system. A given image from the image library is selected by the target system based on the received source image. The selected given image is transformed into a copy of the virtual machine image by receiving blocks from a source system that are part of the virtual machine image but not a part of the selected given image, such that only the blocks missing from the selected given image are transferred from the source system to the target system in order to form the copy of the virtual machine image. The source image is preferably a virtual data processing system image.
