  1. Just tried today with 4.3.26 and it did not work. The development tools installed fine, but the VBoxLinuxAdditions.run failed.

  2. Thanks, work great. You have to insert one line:

    sudo mount /dev/cdrom /media/cdrom/

    cd /media/cdrom

    Greetings Frank

  3. My CentOS 7 server with no UI wouldn’t auto-mount the CD, so I had to do that manually:

    $ sudo su –
    # mount /dev/sr0 /mnt
    # cd /mnt
    # ./VBoxLinuxAdditions.run

    Umounting is unnecessary because you want to reboot after installation anyway …
