Hyper-V R2: Building a Hyper-V R2 Cluster: The following video introduce you to some of the new capabilities in Hyper-V R2 (download) clustering and migration capabilities.

Making Highly Available VMs: In this video, we start the creation process on top of our freshly built cluster.  I go on to create 2 highly available VMs, utilising the newly integrated Failover Cluster MMC Hyper-V tools, which really simplifies the whole process of deploying HA VM workloads.  These 2 VMs have slightly different back-ends; the first, is a regular VHD based VM, with that VHD residing on it’s own LUN on the SAN.  The 2nd VM however, utilises Pass Through Disk capabilities, so the VM in this example, is reading/writing to a raw LUN on the SAN.

Introducing Cluster Shared Volumes: In this video, we enable CSV, but also go on to quickly create a couple of HA VMs, using CSV as their backend.

Failover & Live Migration: This video perform a number of Live Migrations, for the different VM types (VHD, Pass Through Disk and CSV), including using PowerShell for the migration and we wrap up with a failover of the workloads, when I cold-shutdown one of the physical servers, which just happened to have all 4 of our VMs on.  Needless to say, the technology kicked in, and within a minute or so, the VMs were up and running again.
