VirtualBox Centos 6 problems installing VboxGuetsAditions

Today I have installed a Centos 6 in my VirtualBox machine and i tried to create a shared folder to interchange file between de host and guest machine.







I have tried to add the GuetsAditions "inserting" the CD and installing



When i tried to install the software executing the autorun.sh




I recived in the same window the next error:

Look at /var/log/vboxadd-install.log to find out what went wrong

When I opened the file the error is the next one:

Makefile:181: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop


The problem is that you not have installed all the linux headers properly in your machine.

I recommend two steps:

1 - yum update 

In order to update all your virual machine specially if have been recently installed.

2 - yum install kernel-devel 

This package provides kernel headers and makefiles sufficient to build modules against the kernel package.

Restart your Centos virtual machine and try to execute again the autorun.sh

Evething works!!!
