Trevor, Thanks for your response. Reason to go with CentOS5.5 Our current production server is running CentOS 5.5 and the plan is to have another server with the same OS level, so later we can copy the data from the current Prod to the new server and have the secondary server as a stand by server in case of catastrophic situation. CentOS Live CD is an open source project that provides users with a multitude of ISO images designed from the ground up to be used by people who want to just test the CentOS operating system, without installing anything on their computers.

VirtualBox on CentOS 7 or 6 or 5 Linux can be used to create different virtual machines for testing and learning purpose. The usage of open source VirtualBox will be the same for Windows, macOS or Linux, the only discrepancies you will find is in the installation process. Thus, here is the step by step guide to install Virtualbox software latest version on CentOS or RedHat Linux.
