VirtualBox Guest Addition Installation

Post by femio » 2019/05/14 19:47:29

New to CentOS. Can't workout why i can't get full screen
Seems to have to do with ...Kernel headers not found for target headers
Please install them and execute /sbin/rcvboxadd setup
modprobe vboxguest failed

I apologise if this makes no sense or is completely basic, but i hope some will understand my inexperience and help with instructions for a complete beginner.

In addition if i click on Devices > Insert guest additions cd image. I get the following Unable to insert the virtual optical disk c:\program files\oracle\virtualbox\vboxguestadditions.iso into the machine centos

First, you need to install kernel headers:

Code: Select all

yum install kernel-headers
Then, you need to make VirtualBox attach the guest additions DVD and install from there.

Thank you

I successfully installed kernel headers with the yum install kernel-headers as suggested, but still getting the same error. I have attached some shots with the hope they will help.
Can't copy from guest to host until I've installed guest additions hence the screenshots.

What is the content of the setup log (in your last screenshot)?
You can use pastebin.com to paste it there.

The version of kernel-devel needs to match the version of the running kernel exactly. If you run uname -r then that is the version of the kernel-devel package that needs to be installed so to check if it is, run rpm -q kernel-devel-$(uname -r). Now reboot into the latest kernel and try that again and see if it gives output now?
