QEMU模拟运行Zircon（原Magenta）

一 、下载源码：

    $ git clone https://github.com/fuchsia-mirror/zircon.git

or $ git clone https://fuchsia.googlesource.com/zircon

二、安装编译工具链：

    进入源码目录执行（需要科学上网）

    $ cd zircon

    $ ./scripts/download-toolchain

三、编译Zircon：

   $  make -j32 arm64

四、下载QEMU：

    $ cd ..

    $ git clone https://fuchsia.googlesource.com/buildtools

    $ cd buildtools

    $ vim fuchsia.ensure

    $ ./update.sh

    注意：需要下载Google定制的QEMU，亲测QEMU官网或者Ubuntu仓库的QEMU无法正常运行Zircon，会报qemu-system-aarch64: Property '.virtualization' not found错误。

    注意：可以节省下载时间，建议删除fuchsia.ensure中的其他内容，我们只需要下载qemu即可。

fuchsia.ensure最终的内容如下：

五、使用QEMU模拟运行Zircon：

    $ cd ../zircon

    $ ./scripts/run-zircon-arm64

    运行结果见附录。

    在终端中可以执行cd、ls、ps、top等命令，其他的需要进一步研究。

    

    注意：./scripts/run-zircon-arm64会自动识别到magenta/scripts/../../buildtools/linux-x64/qemu/bin/qemu-system-aarch64

或者可以qemu-system-aarch64所在目录添加到环境变量中。
