Have you enabled multiple cores in your VBox configuration, as per the
manual?

        On the "Processor" tab, you can set how many virtual CPU cores
        the guest operating systems should see. Starting with version
        3.0, VirtualBox supports symmetrical multiprocessing (SMP) and
        can present up to 32 virtual CPU cores to each virtual machine.
        
        You should not, however, configure virtual machines to use more
        CPU cores than you have available physically.
