Towards the end of last year, I went to a technet event which was billed as a must see Virtualisation event. We’ll be showing how you can get virtual servers to failover with just Microsoft technologies they said.
And they did, with Virtual Server and Windows 2003 Clustering. It was a very big let down and it wasn’t even automatic. Most people had left before then end of the day, especially as we all thought they were going to show us Hyper-V. In fact, the Vista after hours event afterwards was by far the best part of the day.
Anyway, a few months later and Windows 2008 is out, Hyper-V is at RC and, well, Microsoft are still flogging the horse over clustering as being the solution:-
Yes, Windows 2008 clustering is much easier to configure, but I think the key point is towards the end – “all of the virtual machines will automatically restart to another node without user intervention”. Restart? I want them to carry on running, with, perhaps a small pause. It’s not live migration if the server’s not live!
