Before you attempt to install the Hyper-V role, make sure that you have the following:
A computer running Windows Server 2012.
Enough memory to run all the virtual machines that you plan to run at the same time.
Software for the virtual machine. For example, to test a particular workload, you will need installation media for the operating system and the workload. If you want to test certain features of Windows Server 2012, you can use the same installation media in the virtual machine that you used to install Windows Server 2012 on the physical computer.
Hyper-V requires a 64-bit processor that includes the following:
Hardware-assisted virtualization. This is available in processors that include a virtualization option—specifically processors with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
Hardware-enforced Data Execution Prevention (DEP) must be available and enabled. Specifically, you must enable Intel XD bit (execute disable bit) or AMD NX bit (no execute bit).
