如何處理VirtualBox啟動錯誤訊息：The vboxdrv kernel module is not loaded

我在啟動minikube時，遇到如下錯誤訊息：

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. Please recompile the kernel module and install it by sudo /sbin/vboxconfig You will not be able to start VMs until this problem is fixed. 5.2.18r124319". Please upgrade at  .

Retrying.

核心是這個錯：

The vboxdrv kernel module is not loaded.

執行命令列：

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檔案。參考：

3. 執行命令列：

rcvboxdrv setup

確保看到訊息：

vboxdrv.sh: Building VirtualBox kernel modules.

這個vboxdrv的作用，VirtualBox的幫助文件寫的很清楚：

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：

為了在宿主機裡以虛擬機器的方式執行其他型別的作業系統，VirtualBox需要和宿主機作業系統的Kernel互動，進行互動的模組就稱為vboxdrv驅動，它本身也是作業系統的一部分，負責控制作業系統的CPU和其他硬體資源。如果沒有vboxdrv驅動，我們雖然仍舊可以使用VirtualBox manager來管理虛擬機器，但無法在宿主系統上啟動這些虛擬機器。

rcvboxdrv setup執行後問題解決。
