Domain Controller on Cluster??

Hi Everyone,

I doing Active Directory performance testing running on VMware virtual environment, for that i need to put my DC on Active:Active Cluster configuration, now my question to community is that can we put DC on Cluster because as far as i know you can't add domain Controller on windows  2012 cluster? correct me if i am wrong, my second Question is if "yes" what are the other ways to put DC on Cluster/HA.....

Thanks in Advance..
