If you’re a VMware user, you’re probably familiar with the “vMotion” capability; moving a live, running virtual machine from one host to another. Until recently, that move had to take place among and between clustered hosts, but recently Microsoft Hyper-V (and later VMware in vSphere 5) allowed the live moving of virtual machines without clusters.
Still, clustering is valuable for high availability. I want some mechanism to detect when a host is having problems, and have machines move or re-started on another virtualization host automagically.
In part 12 of March’s “20+ Days of Server Virtualization” series, my Milwaukeen friend Brian Lewis gives us a step-by-step on how to configure high availability using Windows Server 2012, Hyper-V, and NO ADDITIONAL COST*.
“Hey Kevin – you’re posting about articles that were released in March? It’s April. Where have you been?”
Ah, you caught that, did you? It’s been a crazy few weeks of travel, delivering IT Camps, a family vacation to Nashville, TN (which we loved!), and an Azure Bootcamp. So, I’ll be playing catch-up over the next week or two. You have been warned.
* Take that, VMware.
