As part of the on-going VMware article series, earlier we discussed about VMware virtualization fundamentals, and how to install VMware Server 2.
In this article, let us discuss about how to install VMware ESXi.
VMware ESXi is free. However, the software comes with a 60 days evaluation mode. You should register on VMware website to get your free license key to come out of the evaluation mode. Once the ESXi is installed, you can either user vSphere Client on the Direct Console User Interface to administer the host.
VMware ESXi is based on hypervisor architecture that runs directly on top of a hardware as shown below.

1. Download ESXi server
Get the software from the VMware ESXi download page.
Following are the various download options available. Select “ESXi 4.0 Update 1 Installable (CD ISO) Binary (.iso)” and burn a CD.
- ESXi 4.0 Update 1 Installable (CD ISO)
- Upgrade package from ESXi Server 3.5 to ESXi Server 4.0 Update 1
- Upgrade package from ESXi Server 4.0 to ESXi Server 4.0 Update 1
- VMware vSphere Client and Host Update Utility
2. VMware VMvisor Boot Menu
Once you insert the ESXi CD and reboot the server, it will display a boot menu with an option to launch “ESXi Installer” as shown below.

3. VMware ESXi Installer Loading
While the installer is loading all the necessary modules, it will display the server configuration information at the top as shown below. In this example, I was installing VMware ESXi 4.0 on a Dell PowerEdge 2950 server.

4. New ESXi Install
Since this is a new installation of ESXi, select “Install” in the following screen.

5. Accept VMware EULA
Read and accept the EULA by pressing F11.

6. Select a Disk to Install VMware ESXi
VMware ESXi 4.0.0 Installer will display all available disk groups. Choose the Disk where you would like to install the ESXi. It is recommended to choose the Disk0.

7. Confirm ESXi Installation
Confirm that you are ready to start the install process.

8. Installation in Progress
The installation process takes few minutes. While the ESXi is getting installed, it will display a progress bar as shown below.

9. ESXi Installation Complete
You will get the following installation completed message that will prompt you to reboot the server.
10. ESXi Initial Screen
After the ESXi is installed, you’ll get the following screen where you can configure the system by pressing F2.

In the next article, let us review how to perform the initial ESXi configuration.

nice article, waiting for the next part, are you going to describe vSphere Client as well ? I heard that managing vmware ESXi is difficult from command line, so we need to use vSphare client which is not free.
Hi Ramesh,
Great article! Thanks.
I am just starting to learn abt ESXi and was wondering how you could take those screenshots without a client. I know, it may be silly question for those who are already using.
As I understand vSphere (client) comes with it, will that provide the functionality to take screenshots?
Thanks,
Suresh
Ramesh, I’ve been eagerly waiting for the next article on this topic.
Thank you. Great instructions and very simplified.
I understand there is a way to install using graphical mode so you can increase the block size. However, I don’t see anything on install options for GUI mode. Are you aware of this option and how to access? Many thanks!
Thanks Ramesh , very helpful…
