Warning

Warning: Not recommend!

  • Weakens security in general as per [Security Guide] (Harden Virtualbox).
  • Also see article, The VirtualBox Kernel Driver Is Tainted Craparchive.org iconarchive.today icon (w).
  • Additionally they give the Virtual Machine access the the host's (built-in) microphone. Many notebooks have a built-in microphone. In case you install Guest Additions anyway, better cover it up or remove your microphone.
  • Disable clipboard sharing! It is already disabled by default since Whonix 0.5.5. Enable it only temporarily in case you really need it. Go to Virtual Box machine settings -> General -> Advanced -> Shared Clipboard -> Disable -> ok.

Installing VirtualBox Guest Additions

New Instructions for Debian Wheezy

Very simple.

Searchingarchive.org iconarchive.today icon for Debian packages containing Virtual Box was a wise thing. In past it was sometimes a real pain to install the guest additions. The search brought up, that honorable people created a debian package with the tools. Simply do: 

sudo apt-get update && sudo apt-get dist-upgrade

Followed by. 

## If you only want Shared Folder, for improved security,
## you can try using only the next line, but not the line after next.
sudo apt-get install --no-install-recommends virtualbox-guest-dkms virtualbox-guest-utils

## If you want all features, such as dynamic resolution
## and mouse integration.
sudo apt-get install virtualbox-guest-x11

Reboot. And you're done.

Alternatively, if this fails, you could also refer to the upstream documentation, Virtual Box: Chapter 4. Guest Additionsarchive.org iconarchive.today icon.

Old instructions for Ubuntu Precise

Moved to Ubuntu.

Shared Folder

And if you want to use the shared folder read ahead... Go to VirtualBox -> machine -> change -> shared folder -> choose a folder -> use folder name shared. Choose mount automatically and create permanently. Press ok. Use the following commands to mount to folder. 

sudo mkdir -p /mnt/shared
sudo chmod 777 /mnt/shared
sudo mount -t vboxsf -o uid=1000,gid=1000 shared /mnt/shared
If you run into a Protocol Error try using a different name, do not use share, use something else, anything, for example, shared.

Permanently mount Shared Folder

After reboot, you have to repeat the mount command. If you want to mount the folder automatically, have a look at the sourcearchive.org iconarchive.today icon of that information or simply add before exit 0 in your /etc/rc.local: 

sudo mount -t vboxsf -o uid=1000,gid=1000 shared /mnt/shared

Temporary disable Guest Additions

This solution is incomplete! In case you want to temporarily disable Virtual Box guest additions, you can try this. A safer solution would be to uninstall them.

Find out which Virtual box kernel modules are load. 

cat /proc/modules | grep vbox

Create a new config file for module blacklisting. 

sudo nano /etc/modprobe.d/vbox.conf

And add: 

blacklist vboxvideo
blacklist vboxsf
blacklist vboxguest

Safe and reboot. Done.
