Server Core is an excellent platform for running Hyper-V. Because of its minimal installed code, you will have greatly reduced maintenance and reduced attack footprint on the host system. Since Server Core is a minimal installation of Windows Server 2008, you will be working with a text based environment similar to Unix. Also with the minimal code, more of the servers resources can be dedicated to the VMs, and less to the parent OS.
Log into your Server Core with an account that has local administrative rights.
Let’s get a listing of what roles and features have been installed on this server
Type Dism /online /get-features /Format:table and press Enter.
We will see a nicely formatted table of what is on installed, and what is not.
If you scroll down the list you will see Microsoft-Hyper-V is disabled. Let’s enable it.
Type Dism /online /enable-feature /featurename:Microsoft-Hyper-V and press Enter. This command is case sensitive.
Once it has completed, click Y to restart the server.
The Hyper-V role has now been installed.
