HOW TO: Install and Configure VMware vSphere Hypervisor 5.1 (ESXi 5.1)

In my previous VMware Articles, most featured Intermediate VMware Topics, my next series of articles will concentrate on topics for the VMware Novice.

In these series of basic VMware articles, I’ll be showing you the basic skills required to install, configure and deploy virtual machines using VMware’s FREE VMware vSphere Hypervisor.

This article will show you how to install and configure the VMware vSphere Hypervisor 5.1 on a computer. VMware vSphere Hypervisor 5.1 is also known as ESXi 5.1.

The FREE version of ESXi 5.1 is limited to 32GB per server.

  • ESXi 5.1 requires a host machine with at least two cores.
  • ESXi 5.1 supports only LAHF and SAHF CPU instructions.
  • ESXi 5.1 requires the NX/XD bit to be enabled for the CPU in the BIOS.

A full list of the ESXi 5.1 Hardware Requirements can be found in the VMware ESXi 5.1 Install Guide

Check the VMware Hardware Compatability Lists (HCL), to discover if your computer is certified for use with ESXi 5.1.

If your computer is not listed on the VMware HCL, it may still be possible to install and run VMware ESXi 5.1 on your laptop, desktop, or server. The HCL exists because the server vendor and VMware have certified and tested ESXi 5.1 will function correctly, on the servers listed on the HCL.

Register with VMware.com and Download VMware vSphere Hypervisor 5.1

Pay special attention to the FREE License information which is displayed, and record this License Number, this will be required in a later article.

Click the download link for VMware ESXi 5.1 (CD ISO) Installable to download the software required to install ESXi 5.1 and also download the VMware vSphere Client 5.1. The VMware vSphere Client 5.1 software is the client software that allows us to connect and manage the ESXi 5.1 server, this will be required in a later article.

Either use the Download Manager or Manually Download button (which uses your web browser). The CD ISO is only 301MB so should not take too long to download. We have a very slow internet connection, at approx 350 kB/sec, and it takes us approximately 10 minutes to download.

Once the downloads have been completed using your favourite MD5 and SHA1 checksum utility, confirm the downloads have been downloaded correctly, using the published MD5 and SHA1 checksums from the VMware website.  We use the MD5 & SHA-1 Checksum Utiliy 1.1 from http://raylin.wordpress.com/downloads/md5-sha-1-checksum-utility/.

Many VMware vSphere Hypervisor 5.1 installations fail due to corrupt downloads.

Write (Burn) the VMware-VMvisor-Installer-5.1.0-799733.x86_64.iso downloaded in Step 1, to a blank CDROM, using your favourite CD writing software. We use ISO Recorder (http://alexfeinman.com/isorecorder.htm). If you are using remote server utilities, e.g. HP iLo or Dell iDRAC,. you can attach the virtual CDROM drive in the server to the VMware-VMvisor-Installer-5.1.0-799733.x86_64.iso ISO, so there is no requirement to write a CDROM.

This is a step which is often missed, ensure the BIOS BOOT order is set to BOOT from the CDROM Device or ATAPI device in the server, otherwise the computer will not BOOT from the CDROM.

Power on the Computer, the computer will BOOT from the CDROM, and the following BOOT screen will be displayed

The default option is to BOOT ESXi-5.1.0-799733-standard Installer after 10 seconds, hit any key will pause the BOOT process.

ESXi can be installed on a USB flash drive, SD card attached to the computer, local SATA, local RAID Array, or Fibre Channel or iSCSI LUN. All these are supported options. As the footprint for ESXi is very small only 1GB is required for the ESXi OS installation.

We have written an Article here on How to Backup an ESXi installation on an USB Flash Drive or SD card, for security or redundancy. After you have completed the ESXi 5.1 installation, shutdown the server, remove the USB flash drive or SD card, and duplicate it using our Article.

When prompted select a disk to install ESXi on, in the following example, we have two disks connected to this computer, a single 1GB disk, and a 40GB disk. We are going to use the small disk for the OS. The larger 40GB disk will be used later for the storage of virtual machines.
