Prepare to Deploy Hyper-V Replica

https://technet.microsoft.com/en-us/library/jj134153.aspx

Hyper-V Replica is a feature of Hyper-V, so you must enable the Hyper-V server role

If you plan to use a failover cluster with Hyper-V Replica and haven’t already set up the cluster, see http://go.microsoft.com/fwlink/?LinkId=253006

Each node of the failover cluster that is involved in Replica must have the Hyper-V server role installed. If you haven’t already done so, refer to Step 1.2 in this topic and install the Hyper-V role on each cluster node.
