Windows Server 2008 R2 Live Migration: “Overview & Architecture” and “Step-by-Step Guide” Documents Released

Microsoft released in the last days two new more documents about one of the most expected technologies on Windows Server 2008 R2: Live Migration. This new technology will allow you to move any running virtual machine using Hyper-V from Windows Server 2008 R2 or Hyper-V Server 2008 R2 (the free hypervisor offered by Microsoft) to another machine with any of those operating systems, without any downtime or disruption of the service. Here are the two links for the new articles: Windows Server 2008 R2 & Microsoft Hyper-V Server 2008 R2 – Hyper-V Live Migration Overview & Architecture Step-by-Step Guide to Using Live Migration in Windows Server 2008 R2 Here’s an example graphic of how Live Migration setup handles Configuration Files of the virtual machines: It is important for you to notice that Live Migration requires Failover Clustering to be configured on all hosts, access to a shared storage (like in NAS or SAN environments) and a special network configured between them to be used only for Live Migration feature. For more information about Hyper-V Failover Clustering check this guide:Hyper-V Step-by-Step Guide: Hyper-V and Failover Clustering Complete list of requirements for Live Migration: Windows Server 2008 R2 x64 Enterprise Edition Windows Server 2008 R2 x64 Datacenter Edition Live migration is also supported on Microsoft® Hyper-V™ Server 2008 R2. Microsoft Failover Clustering must be configured on all physical hosts that will use live migration Failover Clustering supports up to 16 nodes per […]

Hyper-V Server 2008 R2 Beta Available for Download!

Did you get the chance to try on the free Hyper-Visor released by Microsoft a few months ago, Hyper-V Server 2008?. Don’t get confused, this is not a version of Windows Server 2008, it’s just the hyper-visor released as a "bare-metal" operating system, based significantly on remote administration (nothing much to do locally), but the great feature is that is completely free. Now they’ve also released the R2 version of this operating system, and you can download it from here (~1.2gb). The main improvements from the previous versions: Hyper-V clustering supported! Live Migration. Processor and memory upgrades (up to 32 cores and 1TB of RAM). Includes an Hyper-V configuration utility. I had the chance to work with the first version and it’s been a great experience. Since it’s just an hyper-visor with a really small footprint, has an awesome performance on their virtual machines, including a small attack surface design. One of the significant drawbacks that I found on the first version is that Hyper-V clustering/failover was not supported, but this new release sounded like a great news when I saw that is going to support this feature. Making this free operating system with a great performance, high-available and scalable design. Give this one a chance to test it, you won’t regret it. Check a previous guide I’ve made regarding Hyper-V Server 2008 (applies as well for the R2 version): “Hyper-V Server: Installing, Configuring and Troubleshooting” Cheers!

Hyper-V Server: Installing, configuring and troubleshooting

It’s been a few weeks since its release but I finally managed to put my hands on to Hyper-V Server. I was very curious about it: A free operating system released by Microsoft working only as an HyperVisor it makes wonder about a lot of things. Also recently I’ve been working with VMWare ESX Server 3i, that is also the hypervisor working directly on the machine, and I had a good experience (I really loved the monitoring and reporting features that you can use). From the moment I started using Hyper-V Server few troubleshooting tasks needed to be done. Installing Hyper-V Server If you ever installed any operating system, ever, you should not have any problem with this. You’ll of course see that the process is identical from Vista and Windows 2008. To get started with Hyper-V Server there’s available the Hyper-V Server 2008 Configuration Guide. If you want to avoid almost any command line to be executed from now on, Hyper-V Server has a simple tool where you’ll load a menu to access most of the configurations you will need. You can access it using this cmd: C:windowssystem32hvconfig.cmd But I’ll execute the next steps using the command line features, so this procedure will apply as well for Windows 2008 Server Core. Managing Remotely To start using Hyper-V Server you will need Hyper-V Console on your Vista SP1 (remember: there’s no other option for an Hyper-V Server to be managed […]
