VirtualBox Guest Additions for Windows OSE is a recompiled version of the Guest Additions component of VirtualBox OSE that doesnât require users to generate a new Windows virtual environment in order to successfully create a Guest Additions build.
This will install guest additions matching the Virtual Box version as obtained from the repositories. It is not recommended to install these in newer releases of Virtual Box as obtained from the Oracle repository (see below). Alternatively we can install the package virtualbox-guest-additions-iso in the host Ubuntu.The .iso file with an image of the OSE edition of the guest additions CD will install in the host directory /usr/share/virtualbox/VBoxGuestAdditions.iso.Mount this .iso file as a CD in your virtual machine's settings. In the guest you will then have access to a CD-ROM with the installer.n case something went wrong with installing the guest additions, or the guest OS can not boot after installing we may have to remove the additions. This can be done by running an uninstallation script located in the guest /opt directory.
