So I've fixed the KVM_EXIT_HYPERV_SYNIC in hyperv-stub to do the same feature check as in the real hyperv.c Signed-off-by: Alex Bennée Cc: Vitaly Kuznetsov Cc: Paolo Bonzini Cc: Roman Kagan Message-Id: <20190624123835.28869-1-alex.bennee@linaro.org> Reviewed-by: Vitaly Kuznetsov Acked-by: Paolo Bonzini Reviewed-by: Roman Kagan Signed-off-by: Eduardo Habkost --- target/i386/hyperv-stub.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/target/i386/hyperv-stub.c b/target/i386/hyperv-stub.c index fe548cbae2..0028527e79 100644 --- a/target/i386/hyperv-stub.c +++ b/target/i386/hyperv-stub.c @@ -15,7 +15,7 @@ int kvm_hv_handle_exit(X86CPU *cpu, struct kvm_hyperv_exit *exit) { switch (exit->type) { case KVM_EXIT_HYPERV_SYNIC: - if (!cpu->hyperv_synic) { + if (!hyperv_feat_enabled(cpu, HYPERV_FEAT_SYNIC)) { return -1; }
