My Experience Migrating Hyper-V Clusters Using System Center Orchestrator 2012

Back in August / September last year, I spent sometime designed a set of Orchestrator runbooks to migrate Window Server 2008 R2 Hyper-V clusters to Windows Server 2012. I wasn’t going to blog this because it was designed to only cater for my company’s environment, not something that’s generic enough for everyone to use. I also wasn’t sure how well I can explain and document these runbooks in a blog post. Few of my colleagues and friends actually encouraged me to blog this one so I’ll give it a try (and not to disclose company related sensitive information). Background My

Missing Virtual Machines After An Unexpected Shutdown of Hyper-V Host

I’m not having any luck with computers lately. This is why all my recent posts are related to my troubleshooting experience. Yesterday morning, there were some tradies working in my house fixing a leakage in my shower. I was just about to get in the car leaving home for the MS 70-246 exam, they connected some tools to a powerpoint and popped the safety switch. Therefore all my computers got shutdown unexpectly. I quickly switch the safety switch back on and left home. After I came home few hours later, I turned all the computers back on and made sure

My Home Test Lab – Part 2

This is the part 2 of my 2-part series on how my home test lab is configured. Part 1 can be found here. In this second part, I’m going to talk about my previous experience with vyatta virtual router appliance and how I replaced vyatta with CentOS. Disclaimer: The content of this article is purely based on my personal experience and opinions. I have absolutely no intentions to criticise vyatta. To be honest, I still think it’s a great product, however, it just does not suit my needs in my lab environment. About Vyatta: Stefan Stranger has written a great

My Home Test Lab – Part 1

Background I started a lab environment at home around 2 years ago and I’ve been keep investing in this lab environment over the time. I often get asked how was my lab setup. And most of the time when I tried to answer the question and explain how it was setup, I often forget some components. I have been wanting to properly document it for a long time but never got around to it. Until 2 weeks ago, I had 2 machines with 24GB RAM each running bare-metal Hyper-V 2008 R2 and another desktop with 8GB RAM running Windows 7

Hyper-V virtual machines with “Missing” status

I’m currently running Hyper-V R2 on a machine with 24GB of memory at home. It hosts most of my test machines such as SCCM, SCOM, Exchange, etc. System Center Virtual Machine Manager 2008 R2 (VMM) is installed on a separate box to manage this Hyper-V Host. Few days ago the Hyper-V machine was powered off unexpectly and when it powered back online, in VMM, the status of 2 virtual machines showed as “Missing”. I checked the location where virtual machines are stored and without doubt, the vhd, xml and other files for each virtual machine are still there. I Checked
