Windows Server 2008 is in the RTM process so for all practical purposes, it's shipped. Inside is a beta of Hyper-V. Hyper-V will be setting the stage for a whole new wave of technologies so with that in mind, I thought I'd give you a quick peek at the product via a screencast video I created. I actually published this in September but have re-encoded it for Silverlight streaming.
Hypervisor: I love that name. It's catchy and kewl. It sounds like a supervisor for hyper space or something. It does of course refer to the new thin layer that is installed on Windows Server 2008 also know at the virtualization parent partition. It's also a a term used industry wide so when you hear the term, it doesn't just refer to the Microsoft implementation.
Our hypervisor, code named "Viridian" and now called Hyper-V, is an installable Windows Server 2008 role. After installation of this role, you can start installing one or more child partitions in which to run your virtualization workloads. Installation of those virtual machines is fairly straight forward although there are some things you need to be aware of.
Virtual Machine Additions: In order to use the new high speed VMBUS, you'll want to uninstall any previous additions from Virtual PC or Virtual Server, then install the integration components for Hyper-V. We're looking at making that transition as painless as possible, but you'll have to work through some of this manually until we get that work done.
Snapshots: You'll notice when you start looking at the CTP (and the screencast demo below), that we've added the ability to take snapshots of your virtual machines in either an online or offline state. This gives you a look into the VSS capabilities that are coming. This is going to offer much more flexibility in your high availability and disaster recovery planning.
