It has always been our recommendation that Hyper-V be installed on Windows Server Core in production environments (for performance and security reasons). In Windows Server 2012 we have done a lot of work to make Hyper-V on Windows Server Core an easier option for people to use, through improved PowerShell support and continued investments in remote management.
During my recent presentations at TechED I used a number of different configurations for my various demonstrations. Some of my demos were done using Windows Server Core systems that I managed remotely from a installation of Windows Server with a GUI. Other demos were done using a Windows Server Minimal Server Installation:
In this configuration you do not have Windows Explorer (and many other graphical elements) but you do have access to the graphical server management tools. To open the Hyper-V Manager you just need to type in virtmgmt.msc at the command prompt. You can read more about how to configure a Minimal Server installation over at the Server Core Blog.
