When you try to install the VirtualBox Guest Additions for a Linux guest system, this will fail due to some wired ‘features’ in the installation. This post is based on my experience with VirtualBox 3.0.6 but conceptually it is valid also with current 4.3.x releases.
To perform the installation do the following:
Choose Install Guest Additions... from the VirtualBox menu. Open a terminal window in your guest system. Do a
(the foldername will change depending on the VBox version). Proceed as described below.
1. Cannot execute .run file
When you try to execute the installation file (e.g. VBoxLinuxAdditions-amd64.run), you get an error message like this
[root@integration /]# cd /media/VBOXADDITIONS_3.0.6_52128/ [root@integration VBOXADDITIONS_3.0.6_52128]# ./VBoxLinuxAdditions-amd64.run -bash: ./VBoxLinuxAdditions-amd64.run: /bin/sh: bad interpreter: Permission denied
The solution is to use the command
instead (choosing the right architecture, it was 64bit in this case).
2. Installer complains about missing gcc and Linux kernel headers
The solution to this is to update your kernel to the latest version and install headers and sources for it. VirtualBox requires to compile some drivers when it installs.
yum update kernel
yum install gcc
yum install kernel-devel
Run the installer again and everything should be ok.
