Every time you update manually the kernel of your Linux distro you have to rebuild the modules used by VirtualBox: this process can be made automatic.
Let’s see how.
First of all look for VirtualBox source code on you machine, i will assume /usr/src/virtualbox to be the right directory name.
After that make sure to have all the necessary to build software, but if you have just compiled your kernel i doubt you need something you don’t already have.
Finally edit your “local boot scripts” file (/etc/rc.local or /etc/rc.d/rc.local … i leave to you finding which one is already present on your system) and append to it the following code:
|
1 2 3 4 5 6 7 8 |
VBOXDIR="/usr/src/virtualbox" VBOXOK=$(find /lib/modules/$(uname -r)/ -name 'vboxdrv.ko') if [ "$VBOXOK" = "" ]; then cd $VBOXDIR && \ make clean && \ make && \ make install fi |
Now every time you system boot it will check if the kernel modules for VirtualBox are present and build them if it has to.
