VirtualBox 关于将快照复制为虚拟磁盘以减少磁盘占用的方法。

[午夜芭蕾]

有一个windows虚拟机，现在有一个虚拟磁盘和一个快照：

win2008 副本-disk1.vdi
Snapshots\{86322544-3e23-44b5-8bd7-1cefe99a4d9a}.vdi

系统启动后更新的是快照文件，现在希望把快照复制为win2008 副本-disk1.vdi并删除快照，节省硬盘空间。该如何做？

下面是部分配置：

[win2008 副本.vbox]

<HardDisks>
<HardDisk uuid="{0b6b791b-d07d-4a4a-829d-7fe214992df2}" location="win2008 副本-disk1.vdi" format="VDI" type="Normal">
<HardDisk uuid="{86322544-3e23-44b5-8bd7-1cefe99a4d9a}" location="Snapshots/{86322544-3e23-44b5-8bd7-1cefe99a4d9a}.vdi" format="VDI"/>
</HardDisk>
</HardDisks>

这个我也不是很明白

已解决，方法： 管理-虚拟介质管理，将快照复制为一个虚拟磁盘。此时这个新虚拟磁盘已经是独立文件了。 选择虚拟机，控制-工具-备份，删除快照备份。此时原始的虚拟磁盘和快照就删除了。（不放心就i先做备份） 管理-虚拟介质管理，将新虚拟磁盘文件注册，挂载在虚拟机里。此时用新的虚拟磁盘启动，不再使用旧的虚拟磁盘和快照。
