Microsoft (MS) Hyper-V is a native hypervisor that enables platform virtualization on x86-64 systems. It is a microkernelized hypervisor where a host operating system provides the drivers for the hardware. This approach leverages MS Hyper-V to support enlightenments (the Microsoft name for Paravirtualization) in addition to the hardware emulation virtualization technique. This paper provides a quantitative performance comparison, using different tests and scenarios, between enlightened and emulated Virtual Machines (VMs) hosted by MS Hyper-V server 2012. The experimental results show that MS enlightenments improve performance by a factor of more than two.
