I have been running virtualbox on an Ubuntu 12.04 laptop for a while and it has all worked smooth, but suddenly, probably after a kernel upgrade, the vbox* modules are not loading at boot, if I manually modprobe them, it all works fine, but that should not be needed ...
Looking at the /etc/init.d/virtualbox
, it seems as I should add LOAD_VBOXDRV_MODULE=1
to /etc/default/virtualbox
, but for other machines it works without that line...
Any clues?
