MS Windows image builder for OpenStack Murano


This repository contains MS Windows templates, powershell scripts and bash scripted logic used to create qcow2 images for QEMU/KVM based virtual machines used in OpenStack.

MS Windows Versions

Supported by builder versions with en_US localization:

  • Windows 2012 R2
  • Windows 2012 R2 Core
  • Windows 2008 R2
  • Windows 2008 R2 Core

Getting Started

Trial versions of Windows 2008 R2 / 2012 R2 used by default. You could use these images for 180 days without activation. You could download evaluation versions from official Microsoft website:

System requirements

  • Debian based Linux distribution, like Ubuntu, Mint and so on.

  • Packages required: qemu-kvm virt-manager virt-goodies virtinst bridge-utils libvirt-bin uuid-runtime samba samba-common cifs-utils

  • User should be able to run sudo without password prompt!

    sudo echo "${USER}    ALL = NOPASSWD: ALL" > /etc/sudoers.d/${USER}
    sudo chmod 440 /etc/sudoers.d/${USER}
  • Free disk space > 50G on partition where script will spawn virtual machines because of 40G required by virtual machine HDD image.

  • Internet connectivity.

  • Samba shared resource.

Configuring builder

Configuration parameters to tweak:


  • workdir - place where script would prepare all software required by build scenarios. By default is not set, i.e. script directory would used as root of working space.
  • vmsworkdir - must contain valid path, this parameter tells script where it should spawn virtual machines.
  • runparallel - true of false, false set by default. This parameter describes how to start virtual machines, one by one or in launch them in background.


  • mode - local or remote. In local mode script would try to install and configure Samba server locally. If set to remote, you should also provide information about connection.
  • host - in local mode - is, otherwise set proper ip address.
  • user - set to guest by default in case of guest rw access.
  • domain - Samba server user domain, if not set host value used.
  • password - Samba server user password.
  • image-builder-share - Samba server remote directory.

MS Windows install preparation:

[win2k12r2] or [win2k8r2] - shortcuts for 2012 R2 and 2008 R2.

  • enabled - true of false, include or exclude release processing by script.
  • editions - standard, core or both(space used as delimiter).
  • iso - local path to iso file

By default [win2k8r2] - disabled, if you need you can enable this release in config.ini file.



Run chmod +x *.sh in builder directory to make script files executable.

Command line parameters: - the main script

  • --help - shows usage
  • --forceinstall-dependencies - Runs dependencies install.
  • --check-smb - Run checks or configuration of Samba server.
  • --download-requirements - Download all required and configures software except MS Windows ISO.
  • --show-configured - Shows configured and available to use MS Windows releases.
  • --run - normal run

Experimental options:

  • --config-file - Set configuration file location instead of default.

Use cases

All examples below describes changes in config.ini file

  1. I want to build one image for specific version and edition. For example: version - 2012 R2 and edition - standard. Steps to reach the goal:
  • Disable [win2k8r2] from script processing.

  • Update [win2k12r2] with desired edition(standard).

  • Execute --run
  1. I want to build two images for specific version with all supported by script editions. For example: 2012 R2 and editions - standard and core. Steps to reach the goal:
  • Disable [win2k8r2] from script processing.

  • Update [win2k12r2] with desired editions(standard and core).

    editions=standard core
  • Execute --run

  1. I want to build two images for all supported by script versions with specific editions. For example: versions - 2012 R2 and 2008 R2 and edition - core. Steps to reach the goal:
  • Update [win2k8r2] with desired edition(core).

  • Update [win2k12r2] with desired edition(core).

  • Execute --run
