Kernel driver not installed (rc=-1908 )Every time a virtualbox was initialised after rebooting. This would require the command given to be run with sudo privileges every single time, a lengthy and irritating wait.
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Re-setup the kernel module by executing
This can be simply solved by adding the line "vboxdrv" to /etc/modules
So, in the terminal:
sudo gedit /etc/modules
Copy paste "vboxdrv" (without quotes) onto a line at the bottom of the file
Save and exit
Voila, hopefully problem solved!
