2012 essentials r2: how to "manually" set up host and virtualized 2012e r2?

So 2012e r2 is supposed to make it easier to setup a virtualized server.

How do we set this up? Found this for OEM partners, but looking for "manual setup" directions:

Can one manually install hyper-v on essentials then setup VM, and then remove some roles to get back to a leaner host? I'd like to set this up manually and add particular drivers and Intel RST management, then remove roles

thanks
