There are many ways to implement Windows Server Failover Clustering with Hyper-V. I could actually find five unique methods to do it. Some of them will actually not give you a fully fault-tolerant solution, but most of them actually make sense in specific scenarios (even if only for demonstrations). In any case, just trying to understand and differentiate them will probably be a good exercise.
1 – Parent-based Failover Clustering with two physical servers
In this first scenario, probably the most common one, you implement Windows Server 2008 Failover Clustering at the Hyper-V Parent (Host) level. You will need some shared storage, like a Fibre-Channel or iSCSI SAN.
