<p>前面已经编译了magenta内核</p>
<p>并且准备好了qemu模拟器</p>
<p><br> </p>
<p>进入magenta目录</p>
<p>看下脚本./scripts/run-magenta-x86-64</p>

exec $DIR/run-magenta -a x86-64 "$@"</code></pre>
<br> 以参数-a x86-64执行run-magenta脚本
<br>
<p></p>
<p>先看下帮助信息</p>
<p></p>
<pre class="blockcode"><code class="language-plain">~/fuchsia/magenta$ ./scripts/run-magenta -h
help:
-a <arch> : arm32, arm64, or x86-64
-b : build first
-c : add item to kernel commandline
-d : run with emulated disk
-g : use graphical console
-k : use KVM
-m <memory in MB> : default 512MB
-n : run with emulated nic
-N : run with emulated nic via tun/tap
-o <dir> : build directory
-r : run release build
-u : use uniprocessor
-v : use vnc based display
-x <bootfs> : add eXtra bootfs
-h for help
all arguments after -- are passed to qemu directly</code></pre>
<br> 脚本run-magenta主要是根据平台选择qemu及设置参数
<p></p>
<p>执行./scripts/run-magenta-x86-64</p>
<p>可以看到脚本最终执行的命令</p>
<p></p>
