Common CentOS installation problems in Virtual Box and how to solve them

VMs are a popular and efficient way to install multiple OSs in your computer, for whatever purpose it may be. From testing and developing platform specific applications to virtual networking, they are favored by all and their existence is based on popular choice.

In this walkthrough, we'll talk about VirtualBox, one such VM emulator developed by Oracle. This guide will assume that you have all the necessary pre-requisites already downloaded in your computer. If not, its also available at the end of this post.

With many of its charms, there are a certain set of quirks that can be easily fixed if you go through the following steps:

STEP-1:
The first and foremost step is to go to your BIOS settings and enable Virtualization technology and VT-d feature. Go to your BIOS and enable those two things.



STEP-2:
The second order of things is disabling your Hyper-V. Hyper-V is a microsoft proprietary service that is known to conflict with VirtualBox. If you are not using any Hyper-V applications then its is a good idea to disable this to minimize chances of conflict.
• Hit Windows-key+Q || or type in START(Windows-7 onwards)
• Type "Turn Windows features On or OFF"
• Find Hyper-V and deselect all
• Click OK
  
FINAL STEP:
The final order of things is correct setup. Often more than not, users already have the two pre-requisites given above and are only set-back by improper setup of the system.
• Open VirtualBox and Create a new VM
• Name it CentOS or anything you can identify it with
• Apply the following settings:
  • If your ISO is a 64-bit one, Configure CentOS with RedHat-64 bit
    (Note: This options will not be shown if you do not follow  Step-1. This is actually one of the most common reasons for not being able to install 64-bit systems in VirtualBox)
  • Next step is selecting and loading the correct ISO. For this example, CentOS Minimal ISO is used.
