扩展名“VMAccessForLinux”启用失败

Question

最近，我从上传到Azure存储BLOB定制VHD文件开通一个Linux虚拟机（Centos的7 /资源管理器）。一切似乎但有两个问题，我下面观察罚款：

问题1：首先手动安装最新的VM Linux代理，但是不管我使用PowerShell命令或通过门户网站重新设置用户密码，它总是得到失败在扩展日志中找到下面的错误消息。

同时，VM无法通过门户 我试图删除扩展，然后再次运行此命令，但问题依然坚持重新启动。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，我猜它可能涉及自定义映像或任何代理或扩展无法正常运行，因为Azure图像库中的其他VM提供没有此类问题。请指教....谢谢！

Answer 1

后我手动复制OVF-env.xml从另一个Azure的VM（工作正常），以目前的一个问题1解决了，还需要修改OVF-env.xml诸如此类的主机名和用户名，以确保这些设置匹配电流VM环境。修复之后，“重新启动”按钮和“重置密码”功能将再次在Azure门户上发挥作用！但是现在我正在努力解决问题2，门户网站上的“计算机名称”为空。如果有任何进一步更新，将继续发布。如果您有任何好的想法或专业知识，请在此写下！谢谢！
