[Virtualbox][Archlinux] Upgrade vboxdrv.ko after upgrade Linux kernel

1. search “virtualbox-modules gentoo” on google
2. Go to “Git repository browser”
   
   
   Find out the source code of virtualbox-modules
   
   
3. Download vbox-kernel-module-src-5.0.10.tar.xz from vbox-kernel-module-src
   
4. Method 1: pacman -S linux-headers
   Method 2: find out the kernel version
   uname -a
   Ex: my kernel version is 4.10.13.
   Download from internet.
   
   This is how to compiler kernel code
   Decompress the tarball to build.
   tar xvf linux-4.10.13.tar.gz /lib/modules/4.10.13-1-ARCH/build
   tar to above folder is very import, otherwise ko won't able to insert cause verimage.
   
   include/generated/autoconf.h is generated in the make prepare step.
   If you are trying to build a kernel module, you will also need the make scripts step:
   cd /lib/modules/4.10.13-1-ARCH/build/linux-4.10.13
   
   gunzip < /proc/config.gz > .config
   make oldconfig
   make prepare
   make scripts
   
   
   tar xvf vbox-kernel-module-src-5.0.10.tar.xz
   type "make" will produce vboxdrv.ko


5. After reboot will auto mount the kernel module.
   pacman -S virtualbox-host-dkms
   echo vboxdrv >> /etc/modules-load.d/virtualbox.conf
   echo vboxnetflt >> /etc/modules-load.d/virtualbox.conf
