Let’s just focus on Hyper-V on either 2008 R2 SP1, or Hyper-V on Server 2012. The guests are all modern versions of Windows themselves, either Windows 7 or 8, or 2008 R2 or Server 2012.
Do I really need to install the Hyper-V Integration Services on my guests? Everything seems to work just fine without them. And I understand why they may be necessary on older versions of Windows or of course non-Windows OSes…
I read a bit about what the Integration Services are for, but I could not find any information that was specific enough to convince me that I need to worry about installing them on Win7,Win8,2008R2,etc., guest OSes.
It “works fine” but the performance is going to be much poorer than if you installed Integration Services. This is because it provides paravirtualized drivers for performance-critical virtual disks, network adapter, etc.
