Install VirtualBox Guest Additions

To install VirtualBox Guest Additions, follow these steps:

• Stop the virtual machine.

• Edit the virtual machine settings and from the “System” tab, add a new CD-ROM device to the machine.

• Restart the virtual machine.

• Check the current kernel version:

    $ uname -a
  

• Install some needed dependencies as shown below. Remember to replace the VERSION placeholder with the kernel version from the previous command. packages with the proper kernel_version shown by the previous command:

    $ sudo apt-get -y install dkms build-essential linux-headers-VERSION
  

• Restart the virtual machine:

    $ sudo reboot
  

• From the virtual machine menu, select the “Devices -> CD/DVD Devices -> Choose a virtual CD/DVD disk file” option. Select the VBoxGuestAdditions.iso file. This action simulates inserting a CD-ROM that includes the tools.

  The VBoxGuestAdditions.iso file is usually located in the /usr/share/virtualbox/ directory on Linux, in the C:\Program Files\Oracle\VirtualBox directory on Windows and the Contents/MacOS directory of the VirtualBox package on Mac OS X.

• Mount the CD-ROM and install the VirtualBox Guest Additions:

    $ sudo mkdir /mnt/cdrom
    $ sudo mount /dev/cdrom /mnt/cdrom
    $ cd /mnt/cdrom
    $ sudo sh ./VBoxLinuxAdditions.run --nox11
  

  You can safely ignore the error below if it appears during the installation process:

    Installing the Window System drivers ...fail!
    (Could not find the X.Org or XFree86 Window System.)
  

• Once the process is complete, check that the output resembles that shown below. If it does, the VirtualBox Guest Additions have been successfully installed.
