When it comes to optimizing virtualization performance, there's a long list of best practices that can squeeze the most value out of your servers. Microsoft's virtualization platform, Hyper-V, is no exception.
Hyper-V Integration Services: Let's start with a simple, common sense practice: Ensure that you use the latest version of Hyper-V's integration services. This simple setup program installs the latest available drivers for supported guest OSes (and some that are not officially supported). The result is improved performance when VMs make calls to hardware. This should generally be the first thing one does after installing a guest OS. Keep in mind that updated versions of integration services might be released to improve performance between major releases of Hyper-V.
