Yo estoy teniendo problemas con Virtualización. Se me queda colgado y no llega a arrancar.
Para reproducir el error:
Arrancar el SO en Virtualbox
Instalarlo en HD
Reiniciar a HD e instalar VirtualBox Guest Additions
Reiniciar
Lo curioso es que los primeros reinicios funciona bien, pero después no hay forma de que arranque. Se queda en esta pantalla sin que pueda hacer nada:
