Itt kell állítani?
Amikor elindítom a telepítést ezt a hibaüzenetet írja:

A virtuális gép munkamenetének megnyitása sikertelen: windows 7.
The virtual machine 'windows 7' has terminated unexpectedly during startup with exit code 1.

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.
