Vbox 4.2.12

May you help me ?

Solution 1:

Try loading the kernel module (network filter driver) manually :

sudo modprobe vboxnetflt

Solution 2:

There seems to be a problem with VirtualBox 4.2 and newer kernels. You could install 4.3 from the .deb or by adding their repo from https://www.virtualbox.org/wiki/Linux_Downloads .
