Hyper-v3.0里无法压缩虚拟硬盘！虚拟机为Linux,硬盘为VHDX

你好，

如果是Linux系统，压缩之前需要在Linux里面做些操作。要将标记为DELETE的文件彻底删除，也就是将磁盘上的位置0。具体的步骤可以参考这个链接：

另外关于Hyper-V中Linux的VM的问题，可以发到下面这个对应的论坛，可以获得更好的帮助：

The main problem is that the filesystem is not NTFS, but ext4.

The answer:

1) Download systemrescuecd

http://sourceforge.net/projects/systemrescuecd/files/sysresccd-x86/3.8.1/systemrescuecd-x86-3.8.1.iso/download

2) Add this .iso to the quest OS Ubuntu

3) Start this virtual machine

4) Use zerofree

zerofree /dev/sda1

5) Poweroff this virtual machine

6) Use Hyper-V manager (Edit -> defragmentation)

This vhd was 360 Gb. Now 70 GB.
