Continua na mesma: quando tento iniciar a vm, retorna o erro:
=============================
RTR3Init failed with rc=-1912 (rc=-1912)
The VirtualBox kernel modules do not match this version of VirtualBox.
The installation of VirtualBox was apparently not successful. Executing
'/etc/init.d/vboxdrv setup'
may correct this. Make sure that you do not mix the OSE version and
the PUEL version of VirtualBox.
============================================
De qualquer forma, grato pela ajuda. Continuo tentando.
