Since the Hyper-V role is very resource intensive, you must ensure that the computer system on which you are planning to install the role has sufficient amount of physical memory, processing power, and the motherboard supports the VT technology without which you will not be able to install the Hyper-V role and the virtual machines on the Windows Server 2012.
Once you have verified and you are sure that the target computer system has all the prerequisites in place, and it meets the minimum hardware requirements, here is how you can install the Hyper-V role on the Windows Server 2012 standalone computer or Active Directory domain controller:
- Log on to the computer with the Administrator account (in case of standalone server) or Enterprise Admin or Domain Admin account (in case of Active Directory domain controller).
- If not already started, initialize the Server Manager window by clicking its icon from the bottom left corner of the screen.
- On the opened Server Manager window, from the top right corner, go to the Manage menu from the menu bar.
- From the displayed list, click the Add Roles and Features option.

- On the Select destination server window, make sure that the Select a server from the server pool radio button is selected.

- On the Virtual Machine Migration window, leave everything default for now and click Next.
- On the Default Stores window, click the Browse button to change the default virtual hard disk and Hyper-V configuration files’ locations. (You can leave the default settings intact for the testing purposes, like it is in this demonstration.).
Note: It is important to store the virtual hard disk files to any location other than C:\ in order to prevent the system drive from getting overpopulated and over consumed, which may further result in decreased Windows Server 2012 performance.
- On the Confirm installation selections window, check the Restart the destination server automatically if required checkbox.
- Finally click Install to begin the Hyper-V role installation process on the Windows Server 2012 server.

- Once the installation process completes, and the system restarts, you can start creating the Hyper-V virtual machines on the server.
