Need for Virtualization
Most of us work on Windows OS. Using virtualization technique, you can install an image of Linux OS on your windows host machine. So your windows machine will become the host machine & we can install a guest linux OS on top of that. This way, you can install any necessary software (for DevOps) on linux virtual machine. You don’t have to disturb the setup on your host windows machine.
We would be installing Ubuntu OS image on our windows host machine. Ubuntu is a flavour of Linux. So let us start.
Install Oracle VM Virtual Box
We need to first install the Oracle VM Virtual box. Once we are done with this, we can then setup Ubuntu VM.
So, below are the steps to install Oracle Virtual Box.
Go to https://www.virtualbox.org/wiki/Downloads
Download the Windows hosts package
Just install the above package
After installation, click the desktop icon ‘Oracle VM VirtualBox’, below window would come up
Download Ubuntu desktop image
Next, we will download ‘Ubuntu Desktop’ image from https://ubuntu.com/download#download
Click 20.94 LTS to download image
Install Ubuntu image
Once the image gets downloaded, click ‘New’ icon that you see on Oracle virtual box
Provide name of your new Ubuntu machine (example Ubuntu1). The type automatically changes to Linux and Version changes to Ubuntu (64 bit)
Next
Memory size: 1024 MB
Next, Keep default as shown below
Create
Next
Next
Create
Select Ubuntu1 on the left hand side and click Settings
In the ‘Advanced’ tab, select ‘Bidirectional’ as the 2 dropdown values. This will allow to share files between host machine (windows) and Ubuntu VM and vice-versa
System > Processor tab, enter number of processors as 1
Storage > Select Empty > Click disc icon > Click ‘Choose a disk file’
Select the Ubuntu iso file you downloaded
You would now see the iso image name
Click Ok
Click Start 
to start the Ubuntu installation
Click 
to close the warnings that you see in the above screen
Similarly close other warnings
Finish all the remaining steps by setting up your user id, password etc (pretty straightforward). Once the steps are completed, you would see Ubuntu VM successfully installed
Click 
to show applications
Type ‘terminal’ and hit ‘Enter’, you would enter the terminal app, see below
Double click ‘Terminal’. A terminal session would open, see below
We can now execute any linux commands
So this is how we install an Ubuntu VM on windows host!
We would next see how to connect to Ubuntu virtual machine from our windows machine using SSH plus we will also study about important Linux concepts.
