Intro

Manjaro Linux is one of Linux distros based on Arch Linux.
This is my favorite one because of its flexible user interface and powerful package management.

I have failed in running a virtual machine using VirtualBox, however, not few times.
This has been found to be simply because of my way to install VirtualBox.
Thus I decided to write and record how to fix it in order to escape from failing again.

* note: The official document is here.

Problem

An error occurs when trying to run a virtual machine:

Error messages #1:

Error messages #2:

It says:

• "Kernel driver not installed (rc=-1908)"
• "VERR_VM_DRIVER_NOT_INSTALLED"
• "The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv."

But, to my confusion, there is no '/sbin/vboxconfig' in my Manjaro machine.
I know now this is a problem that some modules in /lib/modules/extramodules-[kernel version]-MANJARO/ such as vboxdrv and vboxpci are missing.

Solution

Preparation

1. Get kernel version

For example, use uname -r command:

$ uname -r

4.14.71-1-MANJARO

Procedure

1. Run Pamac installer.

2. Search "virtualbox".

3. Select "Oracle VM VirtualBox (virtualbox)" and install it.

   

4. When the below modal opens, select NOT "virtualbox-host-modules" BUT "linux[kernel version]-virtualbox-host-modules":

   NOT:

   

   BUT:
   (The version is up to the host machine.)

   

5. Run vboxreload command if there is still an error.

$ sudo vboxreload 

Loading modules: vboxnetadp vboxnetflt vboxpci vboxdrv
