Using Hyper-V with a Domain Controller

Building a new server. Are there any issues with using Hyper-V on a Domain Controller? I'm new to Hyper-V but have plenty of experience with VMWare. Thanks!

Are you asking if you can add the Hyper-V role to a domain controller or put a domain controller on Hyper-V?

It generally isn't recommended to install the Hyper-V role on a DC. It is possible but if you are looking for ideal security, performance, and other best practices it isn't recommended.

Running a DC virtual works however if you have your Hyper-V on the domain and your DC has issues then you could be in for a headache especially if you use another 2012 server as a shared storage space (like a VMware datastore. Server 2012 can even act as a cheap low-end SAN solution) for VM files and VHDs as authentication is needed for the VMs to access the shares and if the DC is down authentication won't work so the VM won't boot. It's a vicious circle. This is (in my opinion) the one major downside to Hyper-V.

Here's a couple things you may want to read for more info:

This is a new server I'll be building. I've been told that there could be problems having a domain controller on a hyper-v box.

My boss bought this client a server with Hyper-V on it but now is asking me to do all this research to find out if there are any problems creating hosts VM's as domain controllers on it.

If it is a small client I'd do it and leave Hyper-V out of the domain. From my previous link http://blogs.msdn.com/b/virtual_pc_guy/archive/2008/11/24/the-domain-controller-dilemma.aspx:


Keep the Hyper-V servers out of the domain

In small deployments you can consider just leaving the Hyper-V servers as part of a workgroup and then running all domain controllers inside virtual machines.  This approach has two problems.  First, you lose the security advantages of running in a domain environment and second, it is hard to have multiple administrators in such an environment (as local user accounts need to be created on each Hyper-V server).  Also, you cannot use all the functionality of SCVMM in such an environment.
