VMWARE Matrix: Lesson 2: You Can Build a Matrix

A Quick guide to VMWare

The Machines have arrived

You are now going to face THE MACHINE! This is the heart of the VMWARE world. Don't panic. You do not have to go blind to acompish this task, nor does your significant other have to die. You just have to believe you can!

Techopedia explains VMware ESXi Server

VMware Inc. developed ESX and ESXi as bare metal embedded hypervisors, which means that they run directly on server hardware and do not require the installation of an additional underlying operating system. This virtualization software creates and runs its own kernel, which is run after a Linux kernel bootstraps the hardware. The resulting service is a micro kernel, which has three interfaces:

  • Hardware
  • Guest system
  • Console operating system (service console)

Some of the distinct features of VMware ESXi Server are:

The ESX architecture uses a service console for management tasks, including script execution and third-party agent installation. ESXi does not have this service console, which significantly reduces the hypervisor code-base footprint. By removing the service console, ESXi migrates the management functionality from a local command line interface to remote management tools.

ESXi's application programming interface-based partner integration model removes the requirement to install and control third-party management agents. This helps to automate routine tasks by using remote command line scripting environments, which include vCLI or PowerCLI.

ESXi includes an ultra-thin architecture, which is not dependent on a general-purpose operating system; however, it continues to deliver all the performance and functionality offered by VMware ESX. VMware ESXi is highly reliable because its smaller code-base presents a lesser attack area with less code to patch.

Due to its thinner architecture, the installation happens in just 10 minutes, with the server booting up in two to three minutes. Also, ESXi can be installed easily and booted even from a USB flash drive. ESXi Server is sold as a built-in hypervisor, which eliminates the need to install the ESXi Server on the hard drive.

ESXi Server has a simple security profile configuration when compared to ESX Server.

ESXi uses a small direct console user interface instead of a full server console.

Because of its more compact size and reduced number of components, ESXi needs considerably fewer patches when compared to ESX. This helps to shorten service windows and reduce security vulnerabilities.

Techopedia explains Hypervisor

The term hypervisor was first coined in 1956 by IBM to refer to software programs distributed with IBM RPQ for the IBM 360/65. The hypervisor program installed on the computer allowed the sharing of its memory.

The hypervisor installed on the server hardware controls the guest operating system running on the host machine. Its main job is to cater to the needs of the guest operating system and effectively manage it such that the instances of multiple operating systems do not interrupt one another.

Hypervisors can be divided into two types:

  • Type 1: Also known as native or bare-metal hypervisors, these run directly on the host computer’s hardware to control the hardware resources and to manage guest operating systems. Examples of Type 1 hypervisors include VMware ESXi, Citrix XenServer and Microsoft Hyper-V hypervisor.
  • Type 2: Also known as hosted hypervisors, these run within a formal operating system environment. In this type, the hypervisor runs as a distinct second layer while the operating system runs as a third layer above the hardware.

Buliding an ESXI Server

Boot the ESXI ISO image from the CD Rom.

Step 1: You will get the following screen once server started. Press Enter to Continue to boot from the CD Drive.

Next it will start to loading the ESXi installer.

The following screen shows the initialization of ACPI.

Step 2: Press Enter to Start the installation.

Step 3: Press F11 to accept the license and continue.

Step 4 : Select installation Drive and Enter to Continue.

Step 5:  Select the Keyboard Layout and Enter to Continue.

Step 6: Type the root password in the two fields, then press Enter to Continue.

Step 7: Press F11 to start the installation.

Now it is installing the VMware ESXi.

Step 8: Enter to reboot after the installation.

Step 9: Now the installation is over. You can find the following image displaying the ip address (IP address is DHCP)  for managing this host.

Go to your web browser and type the url according to the ip address,

You have installed ESXi on one of your machines, designated ESXi-A. After you finish the interactive installation of ESXi, use the direct console to configure your host. Assign the host a specific IP address and review the configuration options that the direct console provides.

As part of the Getting Started with ESXi scenario, you must configure your host with a specific IP address. The direct console lets you configure networking on individual hosts without using the vSphere Client.

After the host finishes the autoconfiguration phase, the direct console appears on the host monitor. Key operations available to you in the direct console include configuring hosts, setting up administrative access, and troubleshooting.


Start the direct console (DCUI) on the host ESXi-A.


Press F2 to access the configuration screen.


Type your administrative login credentials.


In the Login Name text box, type root.


In the Password text box, type my_esx_password.

You set the administrative password in Install ESXi Interactively.


Use the keyboard to select Configure Management Network and press Enter.


Select IP Configuration and press Enter.


Verify that Set static IP address and network configuration is selected, and type the network configuration details.

What happens if you encounter an Agent in ESXI

Hopefully this will not occur at this point in time. If you do encounter an agent, RUN!
