我才知道 host OS 和 guest OS 不能同时挂载一个 usb disk，但是大错已经酿成。 当时我正在 host OS 里从 host OS 的硬盘移动一些文件到 usb disk 上，然后又在虚拟机里加载 usb disk 给 guest OS，结果，usb disk 就自动从 host OS 里卸载了。卸载时一些文件正在移动，突如其来的卸载造成这些文件未成功写入 usb disk，但源文件却已经从 host OS 的硬盘上删除了。 Host OS 是 Fedora，这教训给我一个感觉，Fedora (或者说是 GNOME，我不清楚该责怪谁) 的文件操作机制不够可靠——移动文件时，应该在收到目的文件写入成功信号后才删除源文件。
