Installation of RedHat-8 on Oracal Virtual Box.
Oracle VM VirtualBox is a cross-platform virtualization application. What does that mean? For one thing, it installs on your existing Intel or AMD-based computers, whether they are running Windows, Mac OS X, Linux, or Oracle Solaris operating systems (OSes). Secondly, it extends the capabilities of your existing computer so that it can run multiple OSes, inside multiple virtual machines, at the same time. As an example, you can run Windows and Linux on your Mac, run Windows Server 2016 on your Linux server, run Linux on your Windows PC, and so on, all alongside your existing applications. You can install and run as many virtual machines as you like. The only practical limits are disk space and memory.
Red Hat Enterprise Linux is the world’s leading enterprise Linux platform, now optimized for development. With new developer-centric features like container tools, advanced language support, and application streams, Red Hat Enterprise Linux 8 (RHEL) is the most developer friendly Linux ever.
for installing any OS on the top of the virtual box first we have to download and install the oracle virtual box.
Here is the link to downloading & install Oracle Virtual Box.
After the successful installation of the Virtual Box now we can start creating the virtual machine. for creating any virtual OS we required ISO file of a particular OS.
So here we are going to install RHEL-8 on the top of Oracle Virtual Box.
for that, we required iso file of RedHat-8
here is the link for the download ISO file. or you can download ISO file on the official RedHat website.

Here is the process of yum configuration:
first, open the Terminal:
& then go to etc/yum.repos.d/ location & create a file with any name but the extension should be .repo
In RedHat-8 software located in two folders 1) AppStream 2) BaseOS . so we have to give the location of these 2 folders.
[AppStream]
baseurl file:///run/media/root/RHEL-8–0–0-Base05s-x86 64/AppStream
gpgcheck=0
[BaseOS]
baseurl-file:///run/media/root/RHEL 8.0–0-Baseos nG 64/Baseos
