Virtualbox on centos 7 - Kernel driver not installed (rc=-1908)

Error :
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 :

'/sbin/vboxconfig'

as root.
