擴展名「VMAccessForLinux」啓用失敗

Question

最近，我從上傳到Azure存儲BLOB定製VHD文件開通一個Linux虛擬機（Centos的7 /資源管理器）。一切似乎但有兩個問題，我下面觀察罰款：

問題1：首先手動安裝最新的VM Linux代理，但是不管我使用PowerShell命令或通過門戶網站重新設置用戶密碼，它總是得到失敗在擴展日誌中找到下面的錯誤消息。

同時，VM無法通過門戶 我試圖刪除擴展，然後再次運行此命令，但問題依然堅持重新啓動。任何人都可以建議我如何解決這個問題？非常感謝！！

問題2：門戶網站上的計算機名稱爲空，我猜它可能涉及自定義映像或任何代理或擴展無法正常運行，因爲Azure圖像庫中的其他VM提供沒有此類問題。請指教....謝謝！

Answer 1

後我手動複製OVF-env.xml從另一個Azure的VM（工作正常），以目前的一個問題1解決了，還需要修改OVF-env.xml諸如此類的主機名和用戶名，以確保這些設置匹配電流VM環境。修復之後，「重新啓動」按鈕和「重置密碼」功能將再次在Azure門戶上發揮作用！但是現在我正在努力解決問題2，門戶網站上的「計算機名稱」爲空。如果有任何進一步更新，將繼續發佈。如果您有任何好的想法或專業知識，請在此寫下！謝謝！
