VirtualBox 無法創建新的虛擬機！

我正在嘗試製作一個新的虛擬機，但是 VirtualBox 出現此錯誤然後關閉：

Failed to create a new session.
Callee RC: 
NS_ERROR_FACTORY_NOT_REGISTERED (0x80040154)

在終端中，這顯示給我：

$ virtualbox 
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
        available for the current kernel (3.16.3-1-ARCH) or it failed to
        load. Please reinstall the kernel module virtualbox-host-modules or
        if you don't use our stock kernel compile the modules with

          sudo dkms autoinstall

        You will not be able to start VMs until this problem is fixed.

看來您還沒有載入核心模組“vboxdrv”。使用“modprobe”載入模組，然後嘗試。如果出現問題，請嘗試再次安裝所需的軟體包。arch linux上有一個非常好的文件。
