旧笔记本Android Studio模拟器闪退（VCPU shutdown request）求助

在搭载Core i7 Q720处理器的旧笔记本上，将系统从Win8.1重装为Win10 Pro后，运行Android Studio模拟器时仅短暂显示就闪退，日志中出现「VCPU shutdown request」提示。

已完成的检查：

• Hyper-V处于禁用状态
• CPU支持虚拟化与64位
• HAXM 7.6.5版本已安装可用
• 尝试过卸载重装HAXM
• BlueStacks可正常运行，但VirtualBox无法使用

请求提供问题排查方向。

排查方向建议 #

• 降低AVD系统镜像版本
  Core i7 Q720属于第一代酷睿处理器，不支持EPT和UG虚拟化特性，而API 34的系统镜像对硬件要求较高。建议创建API 28及以下版本的x86/x86_64 AVD，旧版本镜像对虚拟化特性依赖更低，兼容性更好。

• 强制禁用Vulkan渲染
  日志中出现cannot add library vulkan-1.dll: failed，说明当前环境Vulkan支持存在问题。可以：

  1. 编辑AVD配置文件（路径：C:\Users\[你的用户名]\.android\avd\[AVD名称]\config.ini），添加或修改：

     hw.gpu.mode=software
     

  2. 启动模拟器时添加参数：.\emulator.exe -avd [你的AVD名称] -gpu swiftshader_indirect，强制使用软件渲染。

• 关闭系统隐藏虚拟化组件
  虽然Hyper-V已禁用，但Win10可能还有Device Guard、Credential Guard等后台虚拟化组件与HAXM冲突：

  1. 以管理员身份打开命令提示符，执行：

     bcdedit /set hypervisorlaunchtype off
     

  2. 运行gpedit.msc打开本地组策略编辑器，依次进入「计算机配置」→「管理模板」→「系统」→「Device Guard」，启用「关闭基于虚拟化的安全」。
  3. 重启电脑后重试。

• 降级HAXM版本
  HAXM 7.6.5对旧CPU兼容性可能不佳，尝试降级到HAXM 7.5.1或更早版本，旧版本对第一代酷睿CPU的支持更完善。

• 检查BIOS虚拟化设置
  重装系统后BIOS中的虚拟化选项可能被意外关闭：

  1. 重启电脑进入BIOS，找到「Intel Virtualization Technology（VT-x）」选项并确保开启。
  2. 若存在「VT-d」选项，尝试关闭（部分旧主板VT-d会与HAXM冲突）。
