## Abstract

A plurality of virtual disk images are established on a virtual machine. The virtual machine identifies corresponding network address translations for a plurality of disks, each having a corresponding plurality of data sets. The virtual machine installs the corresponding plurality of data sets to the plurality of virtual disks using the corresponding network address translations. An image of the plurality of disks is created, wherein the image contains the plurality of virtual disks with the plurality of data sets.
