Great instructions!
I remember trying this in the past, and coming across Virtual Box
problems with the virtual box shared directories (shared host OS
directory, with client).
I tested and didn't come across those problems this time around.
note: mine was sudo apt-get install linux-headers-2.6.32-37-generic
I was running the VMDK 0.8 image on Virtual box 3.1.6 .
I did notice that after the apt-get update/upgrade, the ubuntu package
manager and aptitude, were still informing me of updates, including a
kernel image.
After installing those updates...
The kernal image updated me from 2.6.32-37 to 2.6.32-38, and must have
disabled some of the Virtual Box the kernel modules.
Installing the new kernel headers, and re-installing the Virtual box
add-ons worked. (after reboot).
I find it odd that apt-get and aptitude would get a different update
list, but based on what I've seen, I'd mildly revise your
instructions...
1. sudo aptitude update
2. sudo aptitude upgrade
Thanks again for this,
Joseph
