Virtual machine disk image installation

Abstract

A processor copies first and second installable binary files into first and second disk images of first and second virtual machines, respectively, before instantiating the images. The processor can copy first installation parameters and second installation parameters into the first image. The processor copies additional first installation parameters and additional second installation parameters into the second image. The processor at least partially executes a first installation process, based on the first installation parameters, to install the first installable binary files, and a second installation process, based on the additional second installation parameters, to install the second installable binary files. The processor at least partially executes the installation processes in an interleaved manner in relation to one another, based on dependencies. After instantiating the images, the processor can execute scripts based on the second installation parameters and the additional second installation parameters to complete installation.
