Thing is, some Hyper-V enlightenments benefit both Windows and Hyper-V and some are specific to Hyper-V. Out of top of my head, 'direct synthetic timers', 'Enlightened VMCS', and 'Enlightened MSR-Bitmap' features are Hyper-V specific. Patch list is pretty long, see for example $ git log --author vkuznets@xxxxxxxxxx --oneline -i --grep 'enlightened.*vmcs' arch/x86/kvm/ and $ git log --author vkuznets@xxxxxxxxxx --oneline -i --grep 'direct.*syn' arch/x86/kvm/ Enlightened MSR-Bitmap is only in kvm/master: ceef7d10dfb6 KVM: x86: VMX: hyper-v: Enlightened MSR-Bitmap support The list is likely incomplete as there are pre-requisites for these patches which may not have the required keywords. There were fixes in other parts of KVM for nested Hyper-V as well but I don't know an easy way to find them (grepping for 'Hyper-V/hyperv' in the log would be a good start but we'll certainly miss something). Please let me know if that's what you're looking for and I'll try to give you more precise information. -- Vitaly
