How to Install RHEL 9.x in Oracle VirtualBox: Step-by-Step Guide for Beginners
Introduction
- Red Hat Enterprise Linux (RHEL) 9.x is a powerful, stable, and enterprise-grade Linux operating system widely used in production environments.
- If you’re preparing for certifications like RHCSA, learning Linux administration, or setting up a local lab for practice, installing RHEL 9.x on a virtual machine is the best place to start.
- Oracle VirtualBox allows you to run RHEL 9.x on your existing Windows, macOS, or Linux system without modifying your host OS. In this blog, you’ll learn how to install RHEL 9.x in Oracle VirtualBox step by step, even if you’re a beginner.
- This guide focuses on clean installation, best practices, and clarity, making it ideal for learners, students, and Linux professionals.
Prerequisites
Before starting the installation, make sure you have the following:
Minimum 8 GB RAM
At least 40 GB free disk space
64-bit processor with virtualization enabled
- Oracle VirtualBox installed
Steps to Install RHEL 9.x in Oracle VirtualBox
Step 1: Download RHEL 9.x ISO
- Create or log in to your Red Hat Developer account
- Download the RHEL 9.x DVD ISO file.
- Scroll to the bottom of the download page to find all available RHEL versions.
- Save the ISO file to a known location on your host machine
Step 2: Create a New Virtual Machine in Oracle VirtualBox
- Open Oracle VirtualBox and click New.
- Enter the following details:
- VM Name: RHEL 9
- VM Folder: Choose the location where the VM files should be stored on the host machine
- ISO Image: Select the RHEL 9.x ISO file you downloaded
- Enter the username and password.
- This user account will be created automatically during installation.
- Configure virtual machine hardware:
- Memory: 4096 MB (minimum recommended)
- CPU: 2 cores (minimum requirement)
- Configure the virtual hard disk:
- Disk Size: At least 20 GB (40 GB recommended for practice)
- Click Finish.
- If you see an image checksum error, follow these steps:
- Power off the virtual machine by closing the window.
- Select the VM –> click Settings –> Storage.
- Under Controller: IDE, remove the existing ISO attachment.
- Click Add Attachment –> select Optical Drive.
-
- Click Add, choose the RHEL ISO file, and click OK.
- To enable SSH access and automatically assign an IP address:
- Select the VM → click Settings → Network.
- Change Attached to from NAT to Bridged Adapter.
- Click OK.
Step 3: Start the Virtual Machine and Install RHEL 9.x
- In Oracle VirtualBox, double-click the VM name to start it.
- Choose Install Red Hat Enterprise Linux 9.x and press Enter.
- Select English as the language and click Continue.
- On the Installation Summary screen:
- Click Installation Destination and click Done (default automatic partitioning is sufficient).
- Set the Root Password.
- Configure Language & Keyboard, Time & Date, if required.
- Under Software Selection, choose:
- Server with GUI or
- Minimal Install (recommended for learning Linux administration).
- Click Begin Installation.
Step 4: Complete Installation and First Boot
- Once the installation is completed, click Reboot System.
- After reboot:
- Click Start Setup → Next → Skip.
- When prompted for user creation:
- Use the same username created during VM creation or
- Create a new user and set a password.
- Click Next to complete the setup.
Step 5: Configure Local Repository
- By default, RHEL systems require access to official repositories to install, update, or manage packages using
yumordnf. - In lab or offline environments the repository manager is not available. So, package installation and updates will not work out of the box.
- To overcome this limitation, you can configure a local repository using the RHEL ISO image. This allows you to:
Install packages without internet access
Practice real-world Linux administration tasks
Prepare effectively for certifications like RHCSA
- Follow this step-by-step guide to configure a local repository: Configure Local Repository in RHEL 9 Using ISO
