vbox创建虚拟机，选择的VDI  固定大小的磁盘，后来发现空间不够，得扩容，请问如何实现？

你好，克隆后是将old删掉吗？我删掉后进不了系统了

可以通过clone方式修改：

While there is no way to actually switch a VDI between fixed-size and dynamic, you can clone the existing VDI into a new one with different settings with VBoxManage.

VBoxManage clonehd [old-VDI] [new-VDI] --variant Standard
VBoxManage clonehd [old-VDI] [new-VDI] --variant Fixed

If you want to expand the capacity of a VDI, you can do so with

VBoxManage modifyhd [VDI] --resize [megabytes]

Resizing only works for dynamic VDI images. However, you can combine the resize information with the conversion information to expand fixed-size VDIs. (E.g., convert a fixed-size image to dynamic, expand it, and then convert the dynamic image back to a fixed-size image.)

If you want to compact the image as much a possibly, be sure to zero out the free space. This can be done in Linux by using the dd command to write endless zeros to a file and then deleting that file. (With the caveat of the reserved space of EXT and other file systems.)
