guest additions

Are installed in the VirtualBox guest to make the guest work more smootly with VirtualBox
must be install from withing the guest machine
it takes care of features such as  automatic resize of the guest screen and the like

menu > devices > install
it will use an iso , which is located in the virtualbox app binaries location , as a dvd drive

you need to mount the additions iso to the guest os dvd, so the machine can install it
( uitleg install : https://docs.oracle.com/cd/E36500_01/E36502/html/qs-guest-additions.html )

  • download corresponding iso : https://download.virtualbox.org/virtualbox/6.1.32/ , moet matchen per VirtualBox versie
    move the iso to install folder
    UPDATE niet altijd op VirtualBox site te vinden , dan op andere sites zoeken , bijvb. :
    https://www.oracle.com/virtualization/technologies/vm/downloads/virtualbox-downloads.html

  • then mount it
    EITHER
    copy the iso to /usr/share/virtualbox/ (root required) which is the location where vbx expects it to be
    however to mount it , via vbx settings this location can not be browsed to, because /var/share folder is not visible in the wizzard
    probarly because vbx was not started as root
    => start vitrualbox as root (i know)
    OR
    ==copy the iso to /mnt/data/VirtualBox-VMs , where there are no permission isuues==

  • install is always done inside the guest machine
    do nou use autoplay , install the VirtualBox Guest Additions from the command line to get all the features we need.
