There are a lot of VMware books out there, but few really make you want to reach for your wallet and buy the book. This is one book that will have a lot of people reaching for their wallets. Critical VMware Mistakes You Should Avoid is written by Larry Loucks who has his fair share of experience in the world of virtualization. Larry Loucks is a twenty-eight year veteran of the IT industry. His experience ranges from engineer to architect to consultant for international IT firms including VMware. Larry also serves as the lead corporate presenter for one of the largest software companies in the world, Quest software, and occasionally presents for other companies such as Dell. He is a recognized authority on many topics including virtualization, disaster recovery, network design and troubleshooting. What’s great about this book is that the author has most likely made some of the mistakes in that are covered in the book, and that’s okay, how else do we learn.

What’s Covered?
This book is the only manual that will deconstruct the common errors encountered firsthand in the IT industry with clear, succinct and illustrated methods of solving these problems. What’s great about this book is it will help the inexperienced VMware admin or users avoid some very critical mistakes. The thing that the book points out right off the bat is that you can make a mistake configuring your ESXi server or vCenter Server and not feel the full effects of your mistake until it’s too late. Also covered in this book is the items that should be taken into account when purchasing licensing. Are you going to scale out your virtual infrastructure or will it never change, most likely the latter is the case. You don’t want to get caught in a situation where you can’t grow with the equipment or licensing that you’ve spent money on.

Should I Buy It?
It really depends on your situation. Is it a good read and very informational? Yes. If you are thinking about venturing down the virtualization road with your IT infrastructure, you can’t miss this book. However, if you are a VMware admin, with technical certifications, you can take it or leave it. Most likely you’ve already made these mistakes and learned from them. If you are simply looking to add a great book to your virtualization library, yes, buy this book and add it to your collection. It’s a fairly short book, only 128 pages, and you can read it cover to cover in a day.

  1. I am a newbie to VMware and am just beginning to train and configure. The biggest mistake on a mininum budget is to not have enough horsepower/hardware on the server to build out my lab and wondering why things are not working or able to build and realize the host hardware will not support what you are trying to build.
    I am reading all I can to come up to speed but trying to avoid mistakes and a book like this would be a Great read for me.
    Thanks for the oppurtunity to get a copy!
    Where is it available from??


    1. Hi Mark, glad you visited my site and read the post. We all were newbies at one point in time, hang in there and you’ll be on top of your game in no time. If you click on the picture of the book or the name of the book in the post, it will take you to Amazon where you can buy it, that is if you don’t win it first.

      Thanks for reading,

    1. Thanks for reading Chris, we all make mistakes, glad you learned from it. Thanks for the compliment on the VCP5 post, hope it helps.


  2. I have made a very big mistake (not that long ago) on our vSphere environment. I thought that the HCL nonsense, and we have started production with our environment on a non supported SAN solution. The VM’s are/where running good, but I can’t move them to other storage anymore. This makes my old unsupported SAN crash. So there is no decent way to move the VM’s then to rebuild them on HCL supported storage.
    Lesson learned: stick to the HCL for production environments.

    I hope to receive a copy of the book, so this will be the last stupid mistake I have made one ouw vSphere environment.

  3. Greg,

    Someone just sent me an email regarding this post. I’d like to personally thank you for taking the time to review this book. I speak with over 3000 virtualization admins (both experienced and inexperienced) each year. My goal with this book was to help as many as I could avoid mistakes that I see week after week and improve the ROI of their investment in virtualization. Just yesterday I spoke with an admin with over 300 VMs (and growing fast) that had the exact problems described in the storage section here. I figure if even one chapter helps an administrator improve performance the benefit of that far outweighs the cost of the book

    So thank you again and thank you to all who have purchased this book! Hopefully one day our paths will cross.

    Have a great weekend,

    Larry Loucks

    1. Larry,
      No problem. It’s a great book, I love it and I’ve made my share of mistakes! Thanks for taking the time to write the book and share your expertise. I’m sure we’ll cross paths at some point, it’s a small world, an even smaller community.


    2. I have read Larry Loucks – Critical VMWare Mistakes you should avoid and would like to know where to locate CPU %READY in VMWARE 4.1/5.0

  4. Good job on the review, I hadn’t heard of this book yet but wan it!

    I made the dreaded mistake of not unplugging the fibers from an ESX box I was doing a re-install on. Laid ESX 3.5 down on top of what used to be a big Oracle server. Fortunately, I only destroyed one VM instead of 20!

  5. Congratulations Chris Coleman, the book is yours! Setting up thin provisioning without proper management and alerts surely caused you lots of headaches. That’s a decent mistake. Read the book, don’t make anymore critical mistakes! Thanks again Larry for writing such an original book on VMware.

    Shoot me an email with your shipping address and I’ll get the book in the mail. gregwstuart at gmail dot com.
