最近我从上传到Azure存储blob的自定义VHD文件中配置了一个Linux虚拟机（Centos 7 / Resource Manager）。除了我在下面观察到的两个问题外，一切看起来都很好：
问题1：首先手动为linux安装最新的VM代理，但无论我使用powershell命令还是通过门户重置用户密码，它总是会失败，并在扩展日志中找到以下错误消息。

同时VM无法通过门户重启 我试图删除扩展然后再次运行命令，但问题仍然存在。任何人都可以建议我如何解决这个问题？非常感谢!!
问题2：门户网站上的计算机名称为空白，我想这可能涉及自定义映像或任何代理或扩展程序无法正常工作，因为Azure图像库中的其他VM配置没有此类问题。请指教....谢谢！
答案 0 :(得分：0)
我将ovf-env.xml从另一个Azure VM（Working Fine）手动复制到当前版本后解决了问题1，还需要修改ovf-env.xml，如hostname和username，以确保此设置与当前VM匹配环境。修复完成后，“重新启动”按钮和“重置密码”功能将重新开始在Azure门户上运行！但是现在我正在努力解决第2个问题，即“计算机名称”在门户网站上是空的。如果有任何进一步的更新，将继续发布。如果您有任何好主意或专业知识，请在这里写下来！谢谢！
