  • Blog Post: Can you run Windows Server 2012 R2 on Windows Server 2008 R2?

    I have been asked this question a couple of times recently.  The odd thing, to me anyway, is that most of the people who have asked me have stated: I read this article: http://msdn.microsoft.com/en-us/library/cc794868(v=ws.10).aspx about supported guest operating systems for Windows Server 2008...
  • Blog Post: Understanding Maximum Dynamic Memory from inside a VM

    Dynamic memory is a great feature that allows Hyper-V administrators to get better utilization of their physical memory.  But it can be hard to tell what is going on from inside of a virtual machine.  There are, however, some things that you can do from inside a virtual machine. The first thing...
  • Blog Post: Why does Hyper-V create a snapshot every time I apply a snapshot?

    I was asked this question today.  My first response was: “It doesn’t”.  But after a bit of thought I realized what was going on for the user in question.  Whenever you take a snapshot of a Hyper-V virtual machine, we capture the point in time data about that virtual machine and then continue...
  • Blog Post: Configuring wide screen resolutions in a Hyper-V virtual machine

    I recently had to do some demonstrations on my laptop – which has a 1366 x 768 display.  This made it hard to use Hyper-V virtual machines, which default to 1024 x 768 and only allow you to configure 4 x 3 resolutions. Luckily, it is actually possible to setup a Hyper-V virtual machine with a widescreen...
  • Blog Post: Using PowerShell to configure live migration networks in a Hyper-V cluster

    A long time ago, Didier Van Hoye asked me how to configure the networks that should be used for live migration by a Hyper-V cluster using nothing but PowerShell.  Unfortunately, I never got around to getting an answer for him – until today. Didier – this one is for you. Now for a bit of background...
  • Blog Post: Dynamic Memory Pro Tip–be reasonable with your startup ram

    Hyper-V now allows you to configure a startup, minimum and maximum memory limit.  If you are like me – you probably leave the startup ram at the default of 512mb – but you should really consider changing it to better suit your environment.  Here is a quick screenshot from one of my Hyper-V...
  • Blog Post: Checking Out System Wide Disk Operations in Hyper-V

    Recently I was working on a Hyper-V server, and was about to restart it, when I remembered that I had logged in with a different user account earlier on in the day.  I had used this other user account to start the creation of a large fixed size virtual hard disk – and I did not know if this operation...

  • Blog Post: Why you should be using BitLocker on your servers

    In Windows Vista we introduced “BitLocker” to Windows – a native full disk encryption technology for Windows.  Most people immediately saw the potential for BitLocker on laptops.  Encrypting your laptop meant that if you were ever unfortunate enough to lose your laptop (through theft or forgetfulness...
