Seeing the same problem as most here with this issue it seems.

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing

'/sbin/vboxconfig'

as root.


I have installed dkms, updated cache/refreshed dnf.
Deleted and re-added the repo, from the original DL repo.
Disable Secure-Boot, and made sure Virtualization was activated.
Ran sudo /sbin/vboxconfig/ only to receive this outcome :

There were problems setting up VirtualBox. To re-start the set-up process, run

When doing the yum installs neither worked, it says I have the kernel when I install it specifically and when I do yum install kernel-core-devel it says it's already installed so not sure... lol

My error log in var/log/vbox-installer.log comes back with :

Makefile:185: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop.


Can anyone please help, new to linux and still learning but not sure what else to try here. Thanks in advance.

Looking at this:
Are you missing build essentials and gcc?

Why are you using yum? It's depreciated. **Use "dnf" instead.***

To update run this first: (as root)
*-::-I had the same problem and it drove me nuts.-::-*

Run this cmd as 'root':

I meant to say dnf, my bad.
and it say no file/directory exists on (sudo /etc/init.d/vboxdrv setup)

dkms is no longer required by Virtualbox, and deprecated as of Virtualbox 5

Good to know, Here is all my outcomes.

Opening VirtualBox:

$ virtualbox
WARNING: The vboxdrv kernel module is not loaded. Either there is no module
available for the current kernel (4.9.7-201.fc25.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.

Then I try to open a new machine on virtual box and it reads:
Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver (vboxdrv) is either not loaded or there is a permission problem with /dev/vboxdrv. Please reinstall the kernel module by executing
/sbin/vboxconfig


so I run sudo /sbin/vboxconfig and it reads:

There were problems setting up VirtualBox. To re-start the set-up process, run
/sbin/vboxconfig
as root.

So i run dnf install kernel-core-devel and dnf install kernel-headers
then it says I already have kernel core 4.9.7-201 installed as well as others,
but I run dnf reinstall kernel-core-devel-4.9.7-201.fc25.x86_64 just incase
to which is says no such thing exists.

When I run sudo /etc/init.d/vboxdrv It says no file or directory, what am I missing. Please help lol

My log file reads back:
Makefile:185: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again. Stop

Secureboot is off, fastboot is off, windows faststartup is off, virtualization is on. I don't know what I'm missing. lol

I haven't installed VB into Fedora in quite awhile. However, with ubuntu, sometimes VB won't create the kernel modules with a particular kernel. For instance, ubuntu 14.04.5 came with kernel 4.4 (if I remember correctly) but VB couldn't create the modules unless I downgraded to kernel 4.3. I had also tried kernel 4.5 and 4.6 and neither of those worked with VB.

It would seem that modules (drivers) are missing and your system is not currently set up to build kernel modules.

You can run this all day long "/sbin/vboxconfig" and it's not going to work because the system isn't set up to do that. The kernel-devel package is required to build external modules.

The current version of VBox is 5.1.14:-

What version of VBox did you install?

If this were my machine this is what I'd try:
-Use dnf to remove VBox.

-Install kernel header and kernel-devel and reboot.

Than install Virtual Box.

Right but kernel headers and kernel-devel are required. I would install them first before installing VBox.

Is it possible Habitual that OP is missing build essentials?

That's good info.thanks-

Sounds like higher versions of the kernel don't have support for that yet.

Not sure why, how or what.
I looked into my modules folder and was missing a file modules.
Never discovered the issue with that kernel.
Fedora recently released a new kernel 4.9.9 I believe.
I built the kernel once the new one installed and to my surprise it worked without any issues.
Not sure why I had an issue with the last one or what the problem was....
Did however gain a little knowledge messing around trying to figure it out so I suppose all is good

Glad to hear that Virtual Box is working correctly now.
