非常突然，打开VirtualBox时，发现工具栏里面之前创建的虚拟机都不见了，自己又没有删，咋回事呢，有些慌，之前的撸力全没有了👿。。。之前有关注过存储文件路径，去找了一下发现*.vdi和*.vbox文件都在啊，网上找了一些资料说是从工具栏“控制”->“注册”里面找回。

网上资源说是用户文件损坏，目录在C:\Users\wenchun001\.VirtualBox\VirtualBox.xml

里面虚拟主机配置节点。。。一个都没有了(⊙o⊙)…

第一种方式

先找到工具栏菜单

查找之前的主机vbox文件

选择.vbox文件打开

第二种方式

重新建主机

跟之前的一样，这里步骤略过。。。

 配置存储->控制器：SATA

删除默认的vdi，选择之前需要恢复的vdi文件。

 配置网络

跟之前的一样，这里步骤略过。。。

 启动主机

这时网络IP和之前一样只是不过多了一组文件。

配置完后

.VirtualBox\VirtualBox.xml文件有数据了

看来是有软件破坏了这个文件，可恶啊
