    Subject[FYI PATCH 14/20] kvm/x86: Hyper-V HV_X64_MSR_VP_INDEX export for QEMU.
    Date
    From: Andrey Smetanin <asmetanin@virtuozzo.com>

    Insert Hyper-V HV_X64_MSR_VP_INDEX into msr's emulated list,
    so QEMU can set Hyper-V features cpuid HV_X64_MSR_VP_INDEX_AVAILABLE
    bit correctly. KVM emulation part is in place already.

    Necessary to support loading of winhv.sys in guest, which in turn is
    required to support Windows VMBus.
