Virtual Domain Controllers with Hyper-V replica

I have two physical machines with Hyper-V roles installed on both.  I wanted to have two virtual DC's on one box and have it replica to the other physical box.  I had the domain set up and everything working fine, but when I do a planned failover, none of the AD snap-ins work.  I get the error that the domain controller does not exist.

Is it possible to have 2012 domain controller replica to another physical box?

Because AD is multi-master anyway and due to the possibility of journal wrap, using Replica with DCs is NOT recommended or supported.  Run Two DCs and let one reside on each Hyper-V server.  If the Hyper-V server fails, you still have the other.  If you want to be extra safe, you COULD replicate them, but DO NOT EVER start them unless BOTH active virtual DCs fail (which would be HIGHLY unlikely).

In that case could I only have one DC in my environment and replicate it.  Then if it fails, I can fire it up on the replica server?  Or is that not a good idea?

Always keep two alive domain controllers for failover and redundency.
Additionally you must backup System state of PDC server incase you require authoritattive restore.

> using Replica with DCs is NOT recommended or supported
Not quite. Read http://technet.microsoft.com/en-us/library/dn250021.aspx , it will prove quite the opposite.

I swear I read Hyper-V Replica was NOT recommended or supported for Exchange and DCs because of how they were designed to begin with.  Of course NOW I cannot find any trace of that article that I remember being on a Microsoft site.

So if I do this, why do I get the error?  From what I'm reading window server 2012 can handle replica....so why does it not work?....

You can build test lad with Windows 2012 Hyper-V to test Windows 2012 Virtual DC with replica.
Then demonstrate steps mentioned in article "http://technet.microsoft.com/en-us/library/dn250021.aspx"
Then check all Directory events and AD functionality for critical and warning events.
if everything is fine, you can go ahead and do it in production
