    Commands needed after Guest Additions ISO has been downloaded, mounted and the appropriate file copied to desktop.
    cd /home/usr/Desktop
    chmod +x
    chmod +x
    sudo ./

    All I had to do was change the settings of the guest OS. In my Lubuntu guest, it was Preferences > LXQT Settings > Monitor Settings. Then I could use scaled mode to make it fill my host screen. It took me so much time to figure this out. I had been severely limited by the default res, since applications used larger window sizes than the screen res. This video really didn't help.

    You don't say what the command is to change the resolution or provide it in the description

    Works like charm.
    For Windows 10 hosts, no need to execute the last command. Just restart the VM.

    The last command was not recognized for me, I went desperate until I realized my resolution is fixed already lmao.

    Just go to setting and look for display and change the scale. It will change the guest. No need to go thru this elaborate procedure

    For those who are using Windows 8/8.1 as host machine, there is no need to enter that last command anywhere. Just shutdown your guest OS machine and start it up again... it automatically switches to a proper resolution!

      My host is Windows 10 and I got the guest additions CD installed, but I can't seem to make anything work in MS-DOS. Do I still need to do that part or does copying the file to the desktop finish it up?

    After installing Guest Additions and quitting VirtualBox, the command to enter into the host computer's terminal is:
    VBoxManage setextradata global GUI/MaxGuestResolution 1272,920
    or some other resolution instead of 1272,920

    What is the url for the terminal? I cannot use the hotkey ctrl+alt+t, also it doesn't appear when im searching for it in the Computer map. I can also not navigate through a menu, which I would blame the low resolution.

    just right click or double click for mac users and then you change the screen resolution according to your will. Simple and fast!

    OSX -> For those that are experiencing "Insert Guest Additions CD/DVD" (and nothing happens). You can locate the Guest Additions ISO from here -> Right click on the VirtualBox icon in OSX Finder and choose Show Package Contents. There it is located in the Contents/MacOS folder. Your looking for the VBGuestAdditions.ISO' - Copy it to your VB machine (desktop for ease), then mount it, run it. This will fix the restraint resolution issues.

    I used virtual box setup a windows 7 vm on my linux computer and actually after I clicked on mount, it took me through a wizard. After the wizard was done all I had to do was hit the resize button and I was done.

  • InterlinkKnight

    Thanks for info, but why it has to be so complicated? Is like linux stay in the 80s, like when we use MS-DOS. Make a simple mouse-click way. I suppose is not the fault of the person that make the video. Maybe is the only way. In that case I blame linux developers. They think everybody must type commands to do stuffs.

    • InterlinkKnight

      @Andrés Schwartz nevertheless, linux is only for geeks. Nothing wrong about that, but that exclude the majority of users to use linux.
      By the way, installing a program or plugin don't seem as advanced task to be force use commands

    • Andrés Schwartz

      Eso es porque hacer aplicaciones visuales sale 'caro'. Y como esto es voluntario, no a todos les gusta hacerlas.
      Igualmente empresas como Canonical sí lo hacen.
      Pero para un usuario desarrollador de linux es muy fácil, cómodo y rápido usar comandos. Es como hablar con alguien diciéndole qué hacer, en cambio hacer clics es lento y limitado, si lo anterior es como decirle a alguien qué hacer, esto último sería como hacerlo tu mismo (obviamente hay menos ganas jaja, mejor que lo haga otro). Depende el caso, pero muchas cosas se pueden hacer con comandos flexiblemente pero pocas se pueden hacer visualmente con clics, excepto si es para diseño, videojuegos, mover elementos gráficos, representación o simulación gráfica, pero para configurar y programar es más práctico y cómodo escribir con un teclado órdenes.

    When I go to DEVICES > drop down menu I do not have the option to "Install Guest Additions"
    The only option I have at the bottom is to "Insert Guest Additions CD Image…"
    Did I install it wrong or something? Im running Mac OSX and the Guest VM is Windows Vista. This entire process has just been frustrating beyond belief!

  • Andrew Jones

    The magic command typed at the host O/S at 2:21 was
    VBoxManage setextradata global GUI/MaxGuestResolution 1272,920
    It looks like it is even simpler now. The installer autoran when I mounted the ISO.
    When I followed the instructions to chmod and run the installer it just uninistalled and reinstalled itself.
    Thanks - very useful.

    I had this error on Lubunt:
    Unable to mount the CD/DVD image /usr/share/virtualbox/VBoxGuestAdditions.iso and
    Could not mount the media/drive /usr/share/virtualbox/VBoxGuestAdditions.iso
    It asked if I wanted to force mount, but the only buttons available were 'Force Unmount' and 'Cancel'.
    The solution to this was to do
    sudo apt-get install virtualbox-guest-x11
    After that I rebooted my machine.

    I'm running Windows 7 Home Premium as Host, and Fedora 18 as my Guest. I am able to install Guest additions, but nothing happens at all, whereas, when i installed Windows 8 beta, and did the same thing, it installed, and I restarted with 1920x1080 without having to make any changes.

  • 00meat Plays
    00meat Plays 6 years ago

    Soooooo... if you go into the virtualbox.xml with a text editor, I used notepad++ and REMOVE the line that spesifies max resolution, turns out it will dynamically adjust to whatever window size you set it to. What moron at Oracle set this as a default? You shouldn't have to go in and remove code to magically make it better.
