Re: [libvirt] [PATCH v4 3/4] qemu: add support for Direct Mode for Hyper-V Synthetic timers

QEMU-4.1 supports 'Direct Mode' for Hyper-V synthetic timers (hv-stimer-direct CPU flag): Windows guests can request that timer expiration notifications are delivered as normal interrupts (and not VMBus messages). This is used by Hyper-V on KVM.
