How to run a Domain Controller within your Hyper-V cluster

Here is a great post showing a new feature in Windows 2012.  Now you can run a Domain Controller within your Hyper-V cluster.  Previously this was a problem as the cluster could not start up without a Domain Controller being available.  Although this situation should be avoided if possible, it is technically possible.

Hyper-V Cluster replication

By -Aaron Whittaker

Here are the short steps to configure Hyper-V Cluster replication, all virtual!:

Create a Domain Controller, x2 Hyper-V hosts in a cluster [production site](only 1 needs to be one to actually work), x2 additional Hyper-V hosts [disaster recovery site].

As this is just a test lab you may wish to do this all from the one Hyper-V host.

Add the 4 hosts to the domain.

To enable Hyper-V on a virtual machine you will need to run the follow commands on each host in powershell.  You cannot add the Hyper-V roles from Server Manager.

DISM /Online /Enable-Feature /all /FeatureName:Microsoft-Hyper-V

DISM /Online /Enable-Feature /all /FeatureName:Microsoft-Hyper-V-Management-Clients


Create a cluster with the default settings (you will need to install the failover clustering role).  Add x2 servers to each cluster.

Go to Windows firewall on the DR Hyper-V hosts.  Find the inbound rule called Hyper-V Replica HTTP Listener rule. Right click ‘enable’ it.

On each cluster create a Hyper-v Replica Broker, as in the screen shot.

Once it is configured wait for it to be running (automatic).

If you go back to the Hyper-V replication settings, you will see they are now greyed out due to the host being in a cluster.

You can configure the cluster replication settings if you wish.  In my demonstration we wont, we will be automatically prompted to do this.  Go failover cluster manager create a basic vm.  Mine cannot be turned on as it is a virtual in a virtual.  Right click the VM, select Replication, Enable Replication.

You get an error asking to configure replica settings.

Configure the settings, I am just using Kerberos with no certificates. This is why you need a domain controller.

Select the appropriate recovery points (remember replication occurs every 5 mins and cant be modified)

All configured, as you can see the VM now appears on both servers.  I can’t turn it on my test VM due to it being a VM inside another VM.

Please leave any comments/sugguestions.
