qemu-system-i386：无法为 qcow2 header 和 refcount table 分配集群：地址错误

Question

无法在 Mac 10.12.6 上启动 Android 模拟器。我注意到一个输出可能是原因： qemu-system-i386：无法为 qcow2 header 和 refcount table 分配集群：错误地址

下面是使用 -verbose 和 -debug all 选项的更多输出：

emulator: Starting QT main loop

emulator: Android qemu version 27.1.7.0 (build_id 4581633) (CL:b5ec07662db0f9d8644e5fbda7040053a8741bfd)

我用谷歌搜索了一下，没有找到任何相关信息。每个代码在这里：https://github.com/qemu/qemu/blob/master/block/qcow2.c 好像打开图片失败了。

更新：创建了一个新图像并收到相同的错误消息。这次模拟器崩溃了，下面是问题报告：

似乎是 qemu 问题？

Answer 1

我的第一个猜测是您的 QCOW2 来宾磁盘映像已损坏。尝试使用 known-good 磁盘映像？

Answer 2

原来qemu被我们合作的安全软件Cylance屏蔽了，因为它检测到敏感的内存读取操作。需要与 IT 团队联系以更改政策以解除阻止。
