Now we will learn how to install Ubuntu Server 18.04 LTS in VirtualBox . Recall that VirtualBox is a platform available for architectures of 32 and 64 through which it will be possible to virtualize multiple systems and thus explore all its functionalities and features without affecting the productive environment or our physical machine..

VirtualBox can be installed on the following operating systems:

Microsoft systems
  • Windows Server 2008 (64-bit)
  • Windows Server 2008 R2 (64-bit)
  • Windows 7 (32-bit and 64-bit)

Click on the Download button located in the Ubuntu Server 18.04 LTS section to start the process of downloading the ISO image..


1. How to create Ubuntu Server 18.04 LTS virtual machine in VirtualBox

Step 1

When VirtualBox has been installed, we access the application and we will create our virtual machine, we have the following options:
  • Click on the New icon
  • Use the key combination Ctrl + N
  • Go to the Machine menu and there select the New option

image

Step 2

In the displayed window we will configure the following information:
  • Name of the virtual machine to create
  • Location where you will be staying
  • Type of operating system to use, in this case we select Linux
  • System version to use, in this case we select Ubuntu (64-bit)

image

Step 3

We click on the "Next" button and the next step is to allocate the virtual memory for the Ubuntu 18.04 LTS virtual machine, the default value will be 1024 MB, but this can be edited using the slider to set a new value :

Step 4

Again click on "Next", and now we find the options for the hard drive, there we have the following options:
Do not add a virtual hard disk
By selecting this option, it will be possible to add the hard disk later before the virtual machine is run.

Create a virtual hard drive now
With this option, by default, a hard disk will be created and its size will be subject to the selected operating system, in the case of Linux it will be 10 GB

Use an existing virtual hard disk file
Thanks to this option we can use a disk in VHD or VDI or VMDK format so that it is implemented in the Ubuntu Server 18.04 LTS virtual machine

Step 5

Select the most appropriate option and again click on "Next" and now select the type of disk to create:

Step 6

The type of disk is related in the way the virtual machine will be used, defined that click on "Next" and then define the way in which the administration of the created disk will work:
Dynamically reserved
This option allows the space on the physical hard disk to be filled as information is hosted on it, but if we delete some of that information, the space will not be recovered.

Fixed size
This option establishes and limits the use of information to the size that we have specified during the creation process

image

Step 7

Click on "Next" and now we will specify the following information:
  • Path where the Ubuntu Server 18.04 LTS virtual machine will be hosted
  • Size of the hard disk to create, the default value is 10 GB

Step 8

Click on the "Create" button to complete the process and we will see our machine created correctly: image
