How-to: Guest Additions for VirtualBox 4.3 - Debian 7

Back to installing the Guest Additions for VirtualBox on Debian 7.0 ("Wheezy"). We've moved up some versions and the Debian 7.2 guest inside VirtualBox 4.3 once again requires Guest Additions for more than just mouse integration.

I'm running the Oracle VirtualBox, not the OSE version that's in the repos, just to add some spice.

Debian will run, but you have to run the guest VM under Gnome Classic since the 3D Acceleration or, more importantly, screen resizing, doesn't work natively. It's Gnome Shell - what did we expect?

Guest Additions is picky about dkms and wanting to build kernel modules. Open the Root Terminal:
apt-get install build-essential module-assistant

Once installed, the module-assistant can fetch the Linux headers:
m-a prepare

Have the Guest Additions CD image loaded in your virtual CD drive (VirtualBox "Devices" menu), but don't expect Autorun to work, it only returns "Error autorunning software. Cannot find the autorun program." Don't ask. Instead, still in the Root Terminal, run:
sh /media/cdrom/ 

and follow the installation prompts. You can then reboot with the 3D Acceleration, display resize and auto-resolution working again.The output in the terminal should look something like this:

root@localhost:/media/cdrom0# ./
Verifying archive integrity... All good.

VirtualBox Guest Additions installer
You appear to have a version of the VBoxGuestAdditions software
on your system which was installed from a different source or using a
different type of installer.  If you installed it from a package from your
Linux distribution or if it is a default part of the system then we strongly
recommend that you cancel this installation and remove it properly before
installing this version.  If this is simply an older or a damaged
installation you may safely proceed.

Do you wish to continue anyway? [yes or no]

Back in business. Why am I running a Debian guest under a Debian host? LaMp stack, but more on that later. RC
