CentOS 6.2: VirtualBox Guest Additions -> Error: unable to find the sources ...

Post by maui_muc » 2012/05/18 10:56:35

Hi there,

I am running CentOS 6.2 as guest OS on an Ubuntu 11.10 host using VirtualBox 4.1.2 from the Ubuntu repositories. I wanted to install the VB Guest Additions as described in the Wiki, http://wiki.centos.org/HowTos/Virtualization/VirtualBox/CentOSguest . Unfortunately, this does not work. The installation process fails and the log files are saying:
[code]tmp/vbox.0/Makefile.include.header:94: *** Error: unable to find the
sources of your current Linux kernel. Specify KERN_DIR=<directory> and
run Make again. Stop.[/code]
[code]Starting the VirtualBox Guest Additions ^[[60G[^[[0;31mFAILED^[[0;39m]^M
(modprobe vboxguest failed) Starting VirtualBox Guest Addition service VirtualBox
Additions module not loaded![/code]
However, the package kernel-devel - as described in the wiki - is installed properly.

Any suggestions what I did wrong?

Cheers, Stefan

You probably need to upgrade your kernel to match the kernel-devel and reboot.

I did a yum update and it installed a couple of new packages. Unfortunately, this does not help. at all. Installed is kernel-devel-2.6.32-220.17.1.el6.i686 and uname -r says 2.6.32-220.el6.i686 .

The log-file suggests defining $KERN_DIR. It is undefined. Where does it has to point at?

Your booted kernel and the kernel-devel are not the same version!

That should not be necessary. Have you rebooted after the update?

If still having problems please show
[code]rpm -qa | grep kernel | sort[/code]
or better yet, [url=http://www.centos.org/modules/newbb/viewtopic.php?topic_id=28723&forum=54]provide more information about your system[/url] by running "./getinfo.sh package" and showing us the output file, and
[code]cat /boot/grub/grub.conf[/code]

It is the same version just the ending is different. When selection the proper one in Grub everything works perfectly fine. Thanks you for your help!

Hello,
I found this year old post but assume that it should still be relevant for CentOS 6.4 and 6.5 (I'm getting the same error on both).

Followed the steps described in this post, but am still getting the "unable to find sources" error.

The output for the above commands are as follows(excluding additional lines I know aren't relevant)

Code: Select all

rpm -qa | grep kernel | sort
abrt-addon-kernelloops-2.0.8.21.el6.centos.x86_64
Dracut-kernel-004-335.el6.centos.noarch
kernel-2.6.32-431.el6.x86_64
kerneldevel-26.32-431.1.2.8.1.3l6.x86_64

Code: Select all

cat /boot/grub/grub.conf
title CentOS (2.6.32-431.el6.x86_64
kernel /vmlinuz-2.6.32-431.el6.x86
initrd /initramfs-2.6.32-431.el6.x86_64.img
As you can see from the above, the "minor" kernel versions are different for the kernel and kernel source, the kernel-devel is slightly different than the running kernel but I don't know that should make a difference, but if it does make a difference, how to modify either the command to compile the VBox Guest Additions or make the kernel and source versions consistent? Of course, I'm sure the correct source has been installed (I understand that in CentOS, there isn't a source package that matches every kernel, you only need to install kernel-devel for the main CentOS version).

TIA,
TSU

You need to have the exact same version numbers on both packages and you need to reboot into the kernel that has a version number that matches the one from kernel-devel. Running `yum update` should be enough to bring both to the same version numbers.

Cool!
As you suggested, "yum update" aligned the source and the running kernel.

After getting over that hump, I encountered the OpenGL module build error which was addressed by
https://community.oracle.com/message/11282251

After that, the VBox Guest Additions was installed successfully.

Thx, again

Is it too late to contribute to this thread? I found that gcc and kernel-devel was not included with the generic desktop install so also needed to do

Code: Select all

yum install -y gcc kernel-devel
after running the updates and rebooting.
