- * '''Hardware assisted virtualization''' - Processors with support for hardware assisted virtualization provide an additional privilege mode above ring 0 (referred to ring -1) in which the hypervisor can operate , essentially leaving ring 0 available for guest operating systems to run. Processors with Intel VT or AMD-V support include hardware assisted virtualization.
- * '''Hardware based Data Execution Prevention''' - Hardware based Data Execution Prevention (DEP) allows the processor to mark sections of memory as non-executable. This feature is available in processors with AMD NX and Intel XD support.

Microsoft's Hyper-V virtualization technology has a number of very strict requirements in terms both operating system and hardware in order to run. In this chapter, an overview of these requirements will be covered in detail.
As indicated in the previous section, a 64-bit CPU is required by Hyper-V. 64-bit processors from both Intel and AMD are supported (excluding Itanium), although the processors must support a number of key virtualization features in order for Hyper-V to run.
Details of the CPU type installed in a system can be obtained from the hardware vendor. Specific CPU features are available in the specification provided by the CPU manufacturer.
== Hyper-V Memory Requirements ==
In order to deploy Hyper-V virtualization on a server it is essential that the system have sufficient memory to host both the parent partition (which requires a miniumum minimum of 1GB of RAM) and the guest virtual machines. The precise requirements will depend on the number of virtual machines that will be run concurrently, further taking into consideration the memory needs of each specific virtual machine.
== Networking Requirements ==
Virtual machines will use the physical network adapters installed into the host system to communicate with the external network. If the host system is to be managed remotely, an additional network adapter will need to be installed for this purpose.
