Just to add to above. After removing the old version as stefano mentioned, I did this:
sudo dkms build -m vboxdrv -v 3.0.6 -k 2.6.31-11-generic sudo dkms install -m vboxdrv -v 3.0.6 -k 2.6.31-11-generic This rebuilt the module (which was needed for me because of the kernel upgrade), then installed it. Checking the status shows I've got everything correct now, and DKMS should setup everything fine on the reboot. dkms status vboxnetadp, 3.0.6, 2.6.31-11-generic, i686: installed vboxnetadp, 3.0.6, 2.6.31-10-generic, i686: installed vboxnetflt, 3.0.6, 2.6.31-11-generic, i686: installed vboxnetflt, 3.0.6, 2.6.31-10-generic, i686: installed vboxdrv, 3.0.6, 2.6.31-11-generic, i686: installed vboxdrv, 3.0.6, 2.6.31-10-generic, i686: installed -- vboxnetflt: Multiple versions in DKMS.
