我在使用 Virtual Box 时遇到问题，无法访问 CentOS 虚拟机。我正在使用连接到网络的 openfiler 本地服务器。此外，我可以访问我在那里创建的所有其他 LUN 磁盘。在搬出旧家之前，我可以完美访问此虚拟机。在 virtualBox 配置中，存储似乎没问题。我已经尝试重置我的计算机，检查用户使用虚拟机的权限，重新安装 virtualbox 管理器，但没有任何效果。如果您知道如何克服这个问题，我将不胜感激。
我的 VIrtualBox 版本是 4.0.12 r72916 我的映射信息

日志文件的第 844 行最有帮助：
00:00:03.413 Guest Log: Could not read from the boot medium! System halted.
回头看，从第 709 行开始，您可以看到 VirtualBox 能够通过 iSCSI 与您导出的 LUN 通信，因此我认为这不是网络问题。我建议尝试将此驱动器连接到可以运行 fsck 并检查启动记录的正常工作的 VM。我猜想是该存储设备出现了问题。
如果您有备份，您也可以尝试将启动信息从好驱动器比较/复制到坏驱动器。
