如何處理VirtualBox啟動錯誤消息：The vboxdrv kernel module is not loaded
我在啟動minikube時，遇到如下錯誤消息：
Starting local Kubernetes v1.10.0 cluster...
Starting VM...
E1010 03:27:37.920050 4827 start.go:174] Error starting host: Error creating host: Error executing step: Running precreate checks.
: We support Virtualbox starting with version 5. Your VirtualBox install is "WARNING: The vboxdrv kernel module is not loaded. Either there is no module available for the current kernel (3.10.0-862.11.6.el7.x86_64) or it failed to load.

Retrying.

核心是這個錯：
The vboxdrv kernel module is not loaded.
執行命令行：
rcvboxdrv setup
結果：
vboxdrv.sh: Stopping VirtualBox services.
vboxdrv.sh: Starting VirtualBox services.
vboxdrv.sh: Building VirtualBox kernel modules.
This system is currently not set up to build kernel modules.
Please install the gcc make perl packages from your distribution.
Please install the Linux kernel "header" files matching the current kernel
for adding new hardware support to the system.
The distribution packages containing the headers are probably:
kernel-devel kernel-devel-3.10.0-862.11.6.el7.x86_64
解決方案：
1. 按照這篇文章的介紹安裝gcc make perl package：
2. 安裝kernel header文件。參考：
3. 執行命令行：
rcvboxdrv setup
確保看到消息：
vboxdrv.sh: Building VirtualBox kernel modules.
這個vboxdrv的作用，VirtualBox的幫助文檔寫的很清楚：
In order to run other operating systems in virtual machines alongside your main operating system, VirtualBox needs to integrate very tightly into the system. To do this it installs a "driver" module called vboxdrv which does a lot of that work into the system kernel, which is the part of the operating system which controls your processor and physical hardware. Without this kernel module, you can still use the VirtualBox manager to configure virtual machines, but they will not start.
我簡單翻譯一下：
為了在宿主機裏以虛擬機的方式運行其他類型的操作系統，VirtualBox需要和宿主機操作系統的Kernel交互，進行交互的模塊就稱為vboxdrv驅動，它本身也是操作系統的一部分，負責控制操作系統的CPU和其他硬件資源。如果沒有vboxdrv驅動，我們雖然仍舊可以使用VirtualBox manager來管理虛擬機，但無法在宿主系統上啟動這些虛擬機。
rcvboxdrv setup執行後問題解決。
