我有一个在 Ubuntu 14.04LTS 上运行的 Windows 7 Professional 64 位虚拟机。我删除了这个 VM 的旧快照。删除花了 30 多分钟，而在该过程结束时，笔记本电脑意外关闭。重新启动笔记本电脑后，我尝试启动虚拟机并出现错误：
Failed to open a session for the virtual machine Main.
Could not open the medium '/home/user/VirtualBox VMs/Main/Snapshots/{eeeeeeeee-ffff-4144-b555-bbbbbb}.vmdk'.
VD: error VERR_FILE_NOT_FOUND opening image file '/home/user/VirtualBox VMs/Main/Snapshots/{eeeeeeeee-ffff-4144-b555-bbbbbb}.vmdk' (VERR_FILE_NOT_FOUND).
Result Code:
NS_ERROR_FAILURE (0x80004005)
Component: Medium
Interface: IMedium {555bbb-a3a6-4b9b9-4949-acacacac}
关于如何恢复它的任何想法？
