Synthetic devices are high-performance software components that control access to physical hardware devices that are designed for optimal performance in virtualized environments. Additionally, because the emulated devices may not have been designed specifically for virtualization purposes, they could also experience performance issues. Emulated devices might experience performance issues because of the overhead of emulation. The advantage of emulated devices is that most operating systems usually have in-box drivers for them. Windows Server 2012 Hyper-V makes emulated and synthetic devices available to the virtual machines.Įmulated devices emulate an existing hardware device that exists as physical hardware. This article summarizes the specifications for supported emulated and synthetic hardware in a Windows Server 2012 environment.Īpplies to: Windows Server 2012 R2 Original KB number: 2844106 Summary
