'hv-vapic' is a prerequisite for some other Hyper-V features, e.g. Enlightened VMCS so disabling it may not be desired. Also, there's 'hv-apicv' (AKA 'hv-avic') feature which prevents AutoEOI advertisement (can't work with APICv and this KVM inhibits it with APICV_INHIBIT_REASON_HYPERV). AFAIR, newer Windows versions don't use AutoEOI either way but Win8/Win7 may. -- You may reply to this email to add a comment.
