这几天鸿蒙电脑的应用市场上架了一款融合开发引擎应用，根据应用描述，它可以运行一个虚拟化的Linux环境，满足开发和调试的需求。

接下来我就使用MateBook Pro简单体验一下这款应用。
首次启动应用，会有一个配置环境的过程，很快。
配置完成后，就可以看到有一个OpenEuler的环境已经准备就绪了。

在这里可以配置磁盘容量、内存大小、CPU核心数量和网络模式，其中内存大小最大是16G，CPU核心数最大是7核（嗯？好像不太对），网络模式有NAT和host-only两种模式。
关于左侧的附加功能：快照备份就不用多说了，用过虚拟机的应该都明白。文件共享可以选择一个鸿蒙电脑本机的目录映射到Linux环境中，实现文件的双向互传。

配置好之后，原神林神，启动！
点击启动之后会弹出一个终端窗口，如果不小心关掉了这个窗口，可以回到融合开发引擎界面里点击打开终端按钮重新打开终端。
因为这只是一个轻量级的虚拟环境，它是不带图形界面的，终端就是我们与它交互的唯一方式。

首先看一下uname -a，可以看到内核版本是6.6.0，这与openEuler 24.03 LTS SP2的内核版本是一致的。
[user@localhost ~]$ uname -a
Linux localhost 6.6.0 #1 SMP Wed Mar 4 04:04:43 UTC 2026 aarch64 aarch64 aarch64 GNU/Linux
既然是欧拉系统，那么欧拉能用的yum和dnf，它自然也可以用：
[user@localhost ~]$ sudo yum makecache
OS 12 kB/s | 1.9 kB 00:00
everything 22 kB/s | 2.0 kB 00:00
EPOL 25 kB/s | 2.0 kB 00:00
debuginfo 19 kB/s | 2.0 kB 00:00
source 19 kB/s | 1.9 kB 00:00
update 22 kB/s | 1.8 kB 00:00
update-source 17 kB/s | 1.8 kB 00:00
Metadata cache created.
我先安装上code-server和node.js，这样我就可以使用codex执行后续的任务了。

首先让codex配置一下开发环境，没有问题，而且sudo默认是没有密码的，它可以直接执行。

对于运维人员来说，docker这类容器引擎是很常用的，但是我遗憾地发现，它是不能安装容器引擎的，因为这个虚拟环境里没有systemd，而是用hsl_init来完成环境初始化的（类似wsl 1？）。
[user@localhost ~]$ ps -aux
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
user 1 0.0 0.0 2040 860 ? Ss 22:03 0:00 /usr/bin/hsl_init
user 2 0.0 0.2 9776 8824 pts/0 Ss 22:03 0:00 /bin/bash
这样的话，即使在上面部署了一些服务，也没法做到开机自启，需要每次手动启动，有些麻烦。
接下来我试着安装了qemu，并在上面跑一台Alpine Linux虚拟机，引导成功了：

先写这么多，后续我再跑一下性能测试啥的。有什么想法也可以说出来，我试一试。
