HOW TO: Create an ISO CD-ROM/DVD-ROM image (*.iso), and MD5 checksum signature, for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1)

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

In this article we will show you HOW TO: Upload an ISO CD-ROM/DVD-ROM image to a VMware datastore for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client, and checking its MD5 checksum signature is correct. There are other third party tools, that can be used to upload ISO image files, these include:-

The above applications, require additional installation and configuration, in this article we will use the VMware vSphere Client.

1

Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) or vSphere vCenter Server using the vSphere Client

Confirming the upload of the ISO image file has been transferred successfully using the MD5 checksum signature

To complete the following step SSH must be enabled and running on your VMware vSphere Hypervisor 5.1 (ESXi 5.1) host server, if SSH is not running you will receive a connection refused message.

To Enable SSH on your VMware vSphere Hypervisor 5.1 (ESXi 5.1) host server, please see my Andysworld! article HOW TO: Enable SSH Remote Access to a VMware vSphere Hypervisor 5.1 (ESXi 5.1)

Connect to the VMware Hypervisor ESXi server via SSH. Using PuTTY a free telnet and SSH client or another SSH client Login and Connect to the VMware Hypervisor ESXi server, using IP address or hostname of the VMware Hypervisor ESXi server, using root username and password credentials. This can also be performed if you have access to the console.

  • PuTTY SSH terminal session

PuTTY SSH terminal session

  • logged in as root to ssh terminal session

logged in as root to ssh terminal session

You will need to change folder or directories to the location of the iso image file. The VMware VMFS datastores are mapped here /vmfs/volumes. Use the following command to change to the datastore1 datastore and isos folder.
cd /vmfs/volume/<datastore name>/<folder name>
  • change folders

change folders

example :- cd /vmfs/volumes/datastore1/isos
type cd /vmfs/volumes/datastore1/isos in the SSH session window.
  • md5sum

md5sum

When you have successfully changed folders to the location of the isos image file which has been uploaded, use the following command to check the MD5 checksum signature.
md5sum <filename>
example md5sum Ubuntu 12.10 amd.iso
  • MD5 Checksum Signature

MD5 Checksum Signature

type md5sum Ubuntu 12.10 amd.iso in the SSH session window. After several minutes, and the time taken, depends on the size of the ISO image file, and speed of host processor and storage, a MD5 checksum signature will be displayed. The number displayed next to the filename – 7ad57cadae955bd04019389d4b

9c1dcb – is the MD5 checksum signature. Compare this number with the original number computed before the ISO image file was uploaded, if they match, the transfer was successful. If they do not match, repeat Step 2 above.Congratulations, you have successfully uploaded an ISO CD-ROM/DVD-ROM image to a VMware datastore for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client, and checked its MD5 checksum signature is correct.

HOW TO: Connect to the VMware vSphere Hypervisor 5.1 (ESXi 5.1) using the vSphere Client

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

This article will show you how to create an ISO CD-ROM/DVD-ROM image (*.iso), and MD5 checksum signature, for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1).

What is an ISO? (Andy’s Laymen Definition)
An ISO is an image or bit copy of a CD-ROM/DVD-ROM, the ISO is a file, similar to a compressed archived file, this *.iso file contains the data from a CD-ROM/DVD-ROM. The ISO file is a virtual CD-ROM/DVD-ROM. Using an *.iso file has many advantages, some are listed below:-

  • The original CDROM/DVD-ROM can be stored securely, and is no longer required, after an ISO image has been created.
  • Multiple virtual machines can use the same *.iso concurrently.
  • Computers without a CD-ROM/DVD-ROM reader can use the data stored on the *.iso file.
  • Installing OS (operating systems) or transferring data is faster.

Prerequisites

  • An original operating system CD-ROM/DVD-ROM
2

Install ISO Recorder

Download ISO Recorder from http://alexfeinman.co/isorecorder.htm We like to use ISO Recorder, because it is a small lightweight application, which integrates into the shell of your OS (operating system). e.g. you right click the CD-ROM/DVD-ROM reader and the option is there to create an ISO.

There are several versions of ISO Recorder to download, ensure you download the correct version for your OS, and the correct version for your processor, as there are 32-bit and 64-bit versions available.

After you have downloaded the correct version, Double-Click the installer program (*.msi) you have download, we will install the Windows 7 64 bit version, which has the filename ISORecorder31x64.msi

  • Welcome to the ISO Recorder Setup Wizard

Welcome to the ISO Recorder Setup Wizard

At the Welcome to the ISO Recorder Setup Wizard dialogue page, Click Next and continue
  • Select Installation Folder.jpg

Insert an original operating system CD-ROM/DVD-ROM into your optical media device.  In this example, we are using an Ubuntu 12.10 DVD-ROM.
  • Right Click the CD-ROM/DVD-ROM

Right Click the CD-ROM/DVD-ROM

Right-Click the CD-ROM/DVD-ROM, and select Create image from CD/DVD.
  • Select Destination for ISO image file

Select Destination for ISO image file

Select a filename and destination folder on your computers hard drive to store the ISO image file and Click Next to continue, this will create an ISO image file.
  • 22 percent complete …

22 percent complete ...

  • 51 percent complete…

51 percent complete...

  • 83 percent complete…

83 percent complete...

The data will be copied from the CD-ROM/DVD-ROM, and the ISO image will be created. This can take several minutes to complete.
  • Completed – Finish

Completed - Finish

Select Finish to complete the operation. The ISO image file has been created.

4

Creating a MD5 checksum signature of the ISO image file

We will use the MD5 & SHA-1 Checksum Utility to create a MD5 checksum signature for our freshly created ISO image file. This is important, so we can compare these signatures, once we have completed the transfer to our VMware host servers, and confirm the ISO image file has not been corrupted in transfer.

  • MD5 SHA-1 Checksum Utility

MD5 SHA-1 Checksum Utility

Double-Click and start the MD5 & SHA-1 Checksum Utility application. Click browse and select your freshly created ISO image file.
  • MD5

MD5

Shortly after selecting the ISO file, the application will start calculating the MD5 and SHA-1 checksums for the file, this can take a few minutes depending upon the size of the ISO image file, which needs to be read.

The MD5 checksum for my Ubuntu 12.10 amd.iso is:-

MD5 Checksum: 7AD57CADAE955BD04019389D4B9C1DCB
SHA-1 Checksum: 8618058554FFD11E317356EC25885BCB8C1D0B36

Generated by MD5 & SHA-1 Checksum Utility @ http://raylin.wordpress.com/downloads/md5-sha-1-checksum-utility

Please note the MD5 checksum value for use with the  VMware vSphere Hypervisor 5.1 (ESXi 5.1)

Congratulations you have successfully created your first ISO (*.iso), and created a MD5 checksum signature for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1).

In my next Article in this series, we will show you HOW TO: Upload and Check the MD5 signature of an ISO CD/DVD image to a VMware datastore using the vSphere Client, for use with VMware vSphere Hypervisor 5.1 (ESXi 5.1)

How to boot a Server or Workstation from a USB Flash drive or USB External Hard disk

Sunday, August 28th, 2011

All the HP ProLiant MicroServers I’ve purchased without CDROM/DVDROM drives, so how did I manage to install all the operating systems, Microsoft Windows Server 2008 R2, Oracle Solaris 11 Express, FreeNAS, VMware ESXi 4.0 and ESXi 5.0 quickly and easily onto the servers.

Well quite simply, I made  my USB External Hard Disk bootable, and copied the ISOs onto the USB External Hard Disk, connected to the HP ProLiant MicroServers, and booted the ISO CDROM from the USB External Hard Disk.

This has the following advantages

1. The read time is much faster than conventional CDROM/DVDROM and USB flash drive.

2. No requirement to burn an ISO image to a CDROM.

3. Keeps all your ISOs in one place.

If you’ve downloaded the software already from the internet, as a download, you already have the ISO ready to configure, otherwise download and install ISORecorder, a brilliant little application, which just creates an ISO image.

Next you’ll need one of the follow applications, and these applications will do the rest, just make sure you set the computer’s BIOS to boot from USB!
