SP2013 DEV environment VM creation - AD machine setup

I'm creating a dev environment, Server 2012 R2 + SP 2013, as a separate virtual machine. My main OS is Win 8.1 Pro. Now, I would like to dual boot to this dev environment. I already know how to achieve that, but the problem lies with AD controller, which needs to be a separate machine. How can I run system from vhd, and simultanously have AD VM running? Can I run another virtual machine inside this SP DEV machine?
