virtualbox manjaro error /sbin/vboxconfig solved kernel 4.14

first check to version kernel

uname -a 

my kernel is 4.14.* for this, i install

sudo pacman -S linux414-virtualbox-host-modules

now activate modprobe

sudo modprobe vboxdrv

sudo adduser your_home_user vboxusers

sudo usermod -aG vboxusers your_home_user

that's all
