I don't want guest additions.

I have Virtualbox on a Windows host running Ubuntu 16.04 LTS as a guest. How do I make sure that all the guest additions are removed from the Ubuntu guest? I so far have run, in Terminal, these:

dpkg -l | grep virtualbox

Which returned: unity-scope-virtualbox

lsmod | grep -io vboxguest

Which returned: vboxguest

Although it doesn't show up as having the typical virtualbox guest additions, the Ubuntu screen size still resizes to the virtual machine's window. Is that actually a part of Ubuntu or from guest additions?

When first installed as a virtual machine, Ubuntu supports mouse pointer integration and screen (virtual machine window) resizing, which are typically from guest additions being installed.

Is there a way to remove the vboxguest kernel module as well?

Thank you.

  • How did you install them ? Did you reboot ? See unix.stackexchange.com/questions/31899/… – Panther Sep 10 '17 at 1:00

    Obvious question... why do you want to remove guest additions? VB won't run correctly without them. – heynnema Sep 10 '17 at 1:14
  • I did not install them. I am looking to remove the ones that come with the initial install of Ubuntu. I'm trying to remove them for security, as I've heard it is better to have them removed for that. – Smiith Sep 10 '17 at 1:20

    So you could update VIrtualBox Guest Additions. It's better. – Redbob Sep 10 '17 at 1:28

From using the commands:

dpkg -l | grep virtualbox
ii  unity-scope-virtualbox      0.1+13.10.20130723-0ubuntu1      all    VirtualBox scope for Unity


lsmod | grep vboxguest
vboxguest   282624  6 vboxsf,vboxvideo

Since you want to remove these packages do as follows:

  1. modules vboxguest:

    • Change into /opt/VBoxGuestAdditions-<version_number> folder

      cd /opt/VBoxGuestAdditions-<version_number>
    • In there run:

      sudo ./uninstall.sh        
  2. For the guest additions unity-scope-virtualbox:

    sudo dpkg-query -s unity-scope-virtualbox
    Package: unity-scope-virtualbox

    • This is used by unity for search and probably be left alone.
  • If the module (vboxguest) is in use, how is it best to remove it? (Prevented from removing it because it was in use. Is there a way to stop it from running so it can be removed? – Smiith Sep 10 '17 at 15:49
  • @Smiith see updated answer for how to... – George Udosen Sep 10 '17 at 17:46
  • I went into /opt/VBox... folder and ran the uninstall.sh to uninstalled the vboxguestadditions. My problem is I opened the ova file in vmware and saw this "vbox kernel service is not running" warning at the start – JCQian May 17 '19 at 18:01
  • @jcqian can you ask a new question? – George Udosen May 17 '19 at 18:29
  • This answer solved my problem. I was able to uninstall the vbox guest additions. – JCQian May 22 '19 at 15:18
