We download the guestfs-tools from below git and compile a local version .

But when we did the test , please see below:

In the Windows the Drive D:\ , the real disk usage is about 19.9-17.7 =2.2G.

Shutdown VM , then we use virt-sparsify on the qcow2 image, but the size is still same as before 6.54G.

It is expected the qcow2 is resized to 2.2G , right ?

Any reason for why the disk size is not returned to host ?

Thanks a lot !

virt-sparsify and some other tools were recently moved into a new

repository:

https://github.com/rwmjones/guestfs-tools

Most Linux distros already ship these tools. You shouldn't really need to compile it all from source yourself (although of course it is possible and you are welcome to try).
