AOSP 模拟器图像未运行

问：

我正在尝试从 AOSP 源代码创建一个 AVD 模拟器映像，我可以在 M1 Macbook （arm64） 上使用标准 Android 模拟器运行该映像。

我遵循了从 https://source.android.com/docs/setup/start/initializing 开始的所有标准步骤，其中包括：

• 设置构建环境
• 克隆源
• 选择此处提到的午餐目标（https://source.android.com/docs/setup/create/avdsdk_phone_arm64
• 创建构建方式m
• 使用（在 Android 13 / 14 上）和（在 Android 11 / 12 上）创建模拟器映像，如此处所述 https://source.android.com/docs/setup/create/avdmake emu_img_zipmake sdk sdk_repo
• 使用生成的系统映像文件创建 AVD

到目前为止，只有 Android 12 版本（从这里 https://android.googlesource.com/platform/manifest/+refs 的 android12-release 分支）给了我一个实际启动且可用的模拟器。

android11-release，，都生成了良好的构建，但模拟器从未启动并且似乎处于循环中，以下是 Android 13 构建的内核日志，这似乎是内核崩溃的相关位置：android13-releaseandroid14-release

从一开始就不确定这些模拟器日志是否相关，但可能会有所帮助

我没有更改 AOSP 源代码上的任何内容，并且所有构建都通过相同的步骤成功。如何获取有效的 Android 13 / 14 模拟器映像？

通过 Android Studio 下载的库存 arm64 模拟器映像工作正常。

我无法在我正在构建的计算机上运行该命令，因为它是在不支持虚拟化的云 Linux 计算机上。emulator
