Bob+Dylanv

As Bob Dylan’s song says, “The Times They Are A-Changin’“. It was not all that long ago that Microsoft Hyper-V was consistently disparaged, spoken of as a second rate virtualization environment.

One example is Elias Khnaser’s December 16, 2009 Information Week commentary titled 9 Reasons Enterprises Shouldn’t Switch To Hyper-V. Reasons included poor memory management, slow Live Migration, lack of VM priority restart, etc. You get the idea. Khnaser spelled it out clearly; he did not feel Microsoft Hyper-V was a hypervisor that met the standards an enterprise required.
This past week, Khnaser posted a follow-up column and his opinion has changed. In his commentary, 9 Reasons Microsoft Hyper-V 3 Is Enterprise-Class, Khnaser presents reasons Hyper-V should be given a serious look.

I am sure Microsoft proponents are feeling good when the features Khnaser examined are listed; Storage Live Migration, Concurrent Live Migrations, Dynamic Memory, Continuous Availability, Network Virutalization and more. Khnaser’s summary is Hyper-V 3 will be the first real challenger to VMware vSphere 5.
Unitrends agrees. When Unitrends Enterprise Backup is soon released, you will see our commitment to supporting Hyper-V. Free and licensed versions will both provide enterprise level backup and recovery. When any size company decides they are ready to deploy Hyper-V, Unitrends will be ready to provide best in the industry protection. What is cool is that we will also be there to protect your physical servers and VMware environment.
Regardless if you make the move from VMware to Hyper-V, just knowing VMware will be feeling heat is a great thing. As Khnaser writes, competition drives innovation and customers ultimately win.

  1. that to me few months back. Though vieruss & spyware are a real threat in Windows 2008 Hyper-V. We had 10 Windows 2008 Server core servers running Hyper-V. They had been running around 100 production virtual machines for the past 2 and half months beautifully. We were very happy with it as we did not have to pay for it due to the fact plenty of the virtual machines are running Windows 2008 & we had Microsoft Premium support in place. The problem that came up 10 days ago, one virus were able to hit our Windows 2008 Server core servers & render them useless with automatic restart every few minutes. We had antigen in place, but somehow the virus were able to render that useless as well. Though after a hard work for 12 hours with MS Support engineers online we were able to bring our infrastructure back from backup. Though that was 12 hours unplanned downtime (not too long for bringing 100 machines back if compared to physical machines, but still a full setup is down for that long is madness), which our management is not accepting and to be honest it risked our jobs for a moment. If it happen again, then you should expect to see my CV. I believe MS Hyper-V is a beautiful product, though a special kernel not running windows & not being affected by vieruss will be great. I am sure VMware & Xen are still affected by some threats , but they are totally immune against vieruss, spyware, & trojans. In addition, it seems VMware reduced size version is even had the smallest surface attack. To be honest our management at the moment is considering if VMware cost is reasonable for at least critical virtual machines to avoid further downtime. Please don’t get me wrong, I really like Hyper-V & agree being free for Microsoft Shops like us is great. Though the virus scenario we had, I can call it a disaster and would be scared of it being repeated. We are considering a change of anti-virus solution as well. If you are going the Hyper-V route, then get my 2 cents advice of securing your Domain 0 machine as much as possible. Don’t connect it to internet. Keep it updated. Ensure that your antivirus solution is the best that you can get. Maybe even put your critical virtual machines on VMware or Xen & the rest on Hyper-V if that is affordable.Good luck & I appreciate ITComparison pointing the security point into their comparison. Its good to have people warned before hand. Although I might still disagree with them on few other points, I will rather e-mail that to them directly.
