Chapter 15 is dedicated to Virtual PC and MED-V. Server virtualization Figure 1.2 is a simple depiction of how to get the most from your server hardware with Hyper-V. Building a Hyper-V virtual environment begins with a hardware platform designed for Windows compatibility. It must be capable of 64-bit operation and be virtual technology enabled. Installed on top of the hardware layer, and abstracting it from future virtual machines (VMs), is the hypervisor. The hypervisor "decouples" hardware from the production operating sys- tems running in the VMs. Configured and managed via the parent VM, it oversees hardware resources by n n Warning Not all processors are compatible with Microsoft Hyper-V. Processors must support hardware-assisted virtualization (i.e., Intel VT or AMD-V technology).
