OpenNebula Windows VM Contextualization


This addon provides contextualization package for the Windows guest virtual machines running in the OpenNebula cloud. Based on the provided contextualization parameters, the packages prepare the networking in the running guest virt. machine, set passwords, run custom start scripts, and many others.


Latest versions can be downloaded from the release page. Check the supported OpenNebula versions for each release.


Documentation on packages installation and guest contextualization can be found in the latest stable OpenNebula Operation Guide. For beta releases, refer to the latest development documentation.

Build own package


On RHEL (CentOS) and Fedora systems, the required binary rhsrvany.exe is distributed as part of the package virt-v2v and placed into /usr/share/virt-tools/rhsrvany.exe. Please copy the EXE into your local repository clone before creating the MSI.


Script builds the MSI package. It's a wrapper around the wixl command from msitools. It reads the package.wxs, a package definition in the WiX-like XML format. Package name or version can be overridden by env. variables NAME and VERSION. For example:

$ TARGET=msi ./
$ NAME=one-context TARGET=msi ./
$ VERSION=1.0.0 TARGET=msi ./

New package is created as ${NAME}-${VERSION}.msi, e.g. one-context-1.0.0.msi in the out/ directory.

Please ignore following assertion on package build, which is caused by skipping the attribute Start in tag ServiceControl. The parameter is optional in WiX specification, but the msitools still counts with it. Despite that, the package is built.

(wixl:22764): wixl-CRITICAL **: wixl_wix_builder_install_mode_to_event: assertion 'modeString != NULL' failed


This addon is largely based upon the work by André Monteiro and Tiago Batista in the DETI/IEETA Universidade de Aveiro. The original guide is available here: OpenNebula - IEETA
