表现

系统升级后AndroID模拟器无法运行，通过命令行启动模拟器运行报错如下：

% emulator -feature HVF -avd Pixel_2_API_29       handlecpuacceleration: feature check for hvfemulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByname: No matching signal for on_new_posture_requested(int) ((null):0, (null))emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByname: No matching signal for on_dismiss_posture_selection_dialog() ((null):0, (null))cannot add library /Users/zhangzhenli/library/AndroID/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libvulkan.dylib: Failedadded library ./lib64/vulkan/libvulkan.dylibcannot add library /Users/zhangzhenli/library/AndroID/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libmoltenVK.dylib: FailedHVF error: HV_ERRORqemu-system-x86_64: Failed to initialize HVF: InvalID argumentHAX is working and emulator runs in fast virt mode.qemu-system-x86_64: Back to HAX acceleratoradded library ./lib64/vulkan/libmoltenVK.dylibemulator: INFO: GrpcServices.cpp:301: Started GRPC server at 127.0.0.1:8554, security: Local

问题原因

谷歌爬了一些发现了大概，简单说就是Big Sur 11.3针对安全性做了升级，现有的qemu没有及时适配。

解决方法

要解决此问题，我们要做的就是为qemu-system-x86_64二进制添加新的权限声明。

创建一个enTitlements.xml文件，内容如下：

<?xml version="1.0" enCoding="UTF-8"?><!DOCTYPE pList PUBliC "-//Apple//DTD PList 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><pList version="1.0">    <dict>        <key>com.apple.security.hypervisor</key>        <true/>    </dict></pList>

签名qemu二进制文件：

 ~ % cd ~/library/AndroID/sdk/emulator/ emulator % codesign -s - --enTitlements enTitlements.xml --force ~/library/AndroID/sdk/emulator/qemu/darwin-x86_64/qemu-system-x86_64

再次启动

 emulator % ./emulator -List-avds                                Pixel_2_API_29emulator %./emulator -feature HVF -avd Pixel_2_API_29handlecpuacceleration: feature check for hvfemulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByname: No matching signal for on_new_posture_requested(int) ((null):0, (null))emulator: INFO: QtLogger.cpp:68: Warning: QMetaObject::connectSlotsByname: No matching signal for on_dismiss_posture_selection_dialog() ((null):0, (null))cannot add library /Users/zhangzhenli/library/AndroID/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libvulkan.dylib: Failedadded library ./lib64/vulkan/libvulkan.dylibcannot add library /Users/zhangzhenli/library/AndroID/sdk/emulator/qemu/darwin-x86_64/lib64/vulkan/libmoltenVK.dylib: Failedadded library ./lib64/vulkan/libmoltenVK.dylibemulator: INFO: GrpcServices.cpp:301: Started GRPC server at 127.0.0.1:8554, security: Local

以上HVF error: HV_ERROR错误消除，成功启动了。
