I attempted to install Windows Server 2012 on a Dell PowerEdge 2850 and found out that the server may not support Server 2012. Is there any downside to running a Windows Server 2012 domain controller from a virtual machine on a Windows Server 2008 R2 server? I know this is possible but I am looking at best practices. I also want to note that this is an additional domain controller as I already have another Windows Server 2012 domain controller on a physical machine (non-virtualized)

The bug I seen in the past was if the DC die, my hyper-v console refused to open. So, like they told try to not create a single point of failure.
