The patch implements userspace exit 'KVM_EXIT_HYPERV' for Hyper-V VMBus hypercalls(postmsg, signalevent) to handle these hypercalls by QEMU.
Changes v3: * use vcpu->arch.complete_userspace_io to setup hypercall result * rebase for 'next-20160211' Changes v2: * use KVM_EXIT_HYPERV for hypercalls Signed-off-by: Andrey Smetanin <asmeta...@virtuozzo.com> Reviewed-by: Roman Kagan <rka...@virtuozzo.com> CC: Gleb Natapov <g...@kernel.org> CC: Paolo Bonzini <pbonz...@redhat.com> CC: Joerg Roedel <j...@8bytes.org> CC: "K.
