Comment 18 for bug 1016165

To get vbox working (meaning "running my existing VMs) in a clean 12.10 installation (previous OS was 12.04) i had to do the following (as root):

# apt-get install build-essential linux-headers-$(uname -r)
# cd /usr/src/virtualbox-4.1.18/vboxdrv
# make
# modprobe vboxdrv
