Step by Step Install Linux 8 (OEL) along with Guest Addition


In this article, we are going to perform step by step install Oracle Enterprise Linux 8.3 along with Oracle VM VirtualBox 6.1.22 install, configure require hardware, network, memory, etc. on VM, and enable guest edition.

To complete this demonstration, we will perform in the below four parts:


1. Install Oracle VM

2. Configure and install Linux 8
3. Enable guest addition
4. Post validations


1. Install Oracle VM

In this section, we will install Oracle VM VirtualBox 6.1.22 on a windows machine to fulfill Linux 8 installation. Click here to download Oracle VM VirtualBox and follow the below step for VirtualBox installation.


1.1. Download software Oracle VM VirtualBox:
Double click on executable (VirtualBox-6.1.22-144080-Win) file to start the installation.

1.6. Click on Install to begin the installation.

 

1.7. Monitor the progress of the installation.


1.8. Check the box to launch VM and click on Finish.


2. Configure and install Linux 8

In this section, we will create a new machine (VM) where we will configure require Hardware, Memory, Network, etc. to install Linux 8. Click here to download OEL ISO  image file. Foll0w the below steps and refer each image and marked in Green Border which are require attention for successful configuration/installation.

3. Enable guest addition

To enable guest addition on OS is one more way for better performance along with copy & paste text, enable shared folder between guest to host vice versa, release the cursor, etc.


3.1 Enable Guest Addition:
Click on Device > Insert Guest Addition CD image.


3.2. Click on Run.

3.3. Authenticate: Provide root password.

As you can see, guest addition failed due to a mismatch of kernel-release. To resolve this issue, we will follow a workaround.


3.4 Workaround: 

3.4.1. Install/upgrade correct gcc and make.

[root@DBsGuruN3 VBox_GAs_6.1.22]# yum -y install gcc make

4. Post validations


Congratulations! The machine is ready to use. We will perform basic validation after successful installation.

4.3 Directory & partition validation: While installation we allocated 500GB harddisk with an auto partition which is divided into 3 partitions, one is used as the root partition, the second is used as /home, and the third used as a boot partition. The root partition is using LVM.
