我想用qemu和kvm在我的jetson nano(arm64(上模拟谷歌紫红色操作系统。这是我正在阅读的指南：

下面你可以看到完整的日志，包括我发出的所有命令和我得到的回复，直到最后一个我无法修复的错误：

错误无法执行忍者。我正试图执行"/opt/fuchsia/pre-buildedthird_party/ninja/linux-arm64/ninja">
我将从源代码指南中指出这一点：
此时，飞行前工具仅作为x64预构建提供。Fuchsia目前不能保证在其他主机架构上成功构建。
因此，这不是官方支持的路径，可能存在尖锐的边缘。每当你在日志中看到Exec format error弹出时，它都与预构建没有在正确的体系结构上运行这一事实有关。这可能是因为预构建的arm64不存在，或者可能是未正确获取。
对于ffx platform preflight，当前没有上载arm64二进制文件(您复制的命令提取了x64二进制文件(。但是，此步骤只帮助验证先决条件。。。不需要完成构建。我已经提交了可能添加对此支持的fxbug.dev/80517。
来自fuchsia/prebuilt的后续错误与引导期间下载的linux-arm64二进制文件的问题有关。我建议将此问题作为功能请求提交到公共问题跟踪器中。
