# Release Note 发布注记

欢迎使用 openEuler 25.09 RISC-V 架构 RVA23 尝鲜版本。

此版本为尝鲜版本，建议作为开发或评估使用。

此版本面向 `QEMU` 等 1 个平台。

## QEMU 镜像使用方式

此版本镜像默认需要 10.0 或更新的 QEMU。
> 将启动脚本 `start_vm.sh` 中的 `-cpu rva23s64` 改为 `-cpu max` 后，稍旧版本（9.0+）的 QEMU 可能也可以启动。

> 此处提供的启动脚本适用于 Linux。

> 若需在 macOS 或 Windows 上运行可能需要修改，如遇到问题可移步 SIG 组社群内讨论。

- 使用 Zstd 解压 .zst 镜像压缩包
  - 注意不是 .tar.zst 不需要 tar
- 执行 QEMU 目录下的 start_vm.sh 启动
- 可通过 SSH 连入，默认端口为 12055
  - 相关配置在启动脚本中，如有冲突可自行修改
- 镜像支持 shutdown 与 reboot，也可通过 `pkill qemu-system-ris` 手动结束运行

## 已知问题

- 已绕过：sd-`journald` 启动失败，挂载文件系统依赖不满足使系统进入紧急模式
    - 日志

        (中略)

        You are in emergency mode. After logging in, type "journalctl -xb" to view
        system logs, "systemctl reboot" to reboot, or "exit"
        to continue bootup.
        Give root password for maintenance
        (or press Control-D to continue): 
        ```

    - 绕过措施：在对应服务的 override.conf 中添加如下内容
        ```
        [Service]
        MemoryDenyWriteExecute=no
        RestrictAddressFamilies=
        SystemCallFilter=
        PrivateMounts=no
        ```
