VM replication between two Hyper-V clusters?

Question

Virtualization

Let me explain the situation, there are two buildings connected by a 10 gigabit network.
There are two clusters of two hyper-v servers and a shared storage for each cluster (fiber channel).
Actually, one cluster is in one building, the second in another. The configurations are identical.
The question is, how to replicate (mirror) virtual machines between two buildings? The task costs in that at shutdown (fall) of one cluster. Virtual machines continued to work on another.

Answer 1

"The next question is how to do replication" - just set up replication, there is nothing complicated there.
"The task is to ensure that when one cluster is disconnected (falling), the virtual machines continue to work on another." - using HYPER-V, automatic start is not possible during replication (switching manually).
