Buongiorno!
ho una cpu q9400 con 4GB ddr2 con una Debian 9 64bit
Linux q9400 4.9.0-4-686-pae #1 SMP Debian 4.9.65-3+deb9u1 (2017-12-23) i686 GNU/Linux
uso Virtualbox da sempre su Debian ora dopo l'ultimo aggiornamento, Virtualbox parte ma tutte le macchine vanno in errore
Kernel driver not installed (rc=-1908)
The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
'/etc/init.d/vboxdrv setup'
as root. If it is available in your distribution, you should install the DKMS package first. This package keeps track of Linux kernel changes and recompiles the vboxdrv kernel module if necessary.
