VirtualBox guest additions installation on CentOS 8

Here's what I did:

1. Disabling SELinux

sudo nano /etc/selinux/config

- change this line:

SELINUX=enforcing

to:

SELINUX=disabled

2. Reboot.


3. Install the required packages

yum install tar bzip2 make automake gcc gcc-c++ kernel-devel elfutils-libelf-devel

4. Reboot.


5. Insert guest additions from the virtual machine's menu: Devices >> Install Guest Additions and follow the installation steps.
