The command used to format blank disk image

[bsapwindows]

Hi Mike, thank you for making this project! :+1:

I'm messing with it recently, but I'm not so familiar with FS and I hope you could help me with the disk image issue.

What I want to achieve is to keep the image size as small as possible. What I did was qemu-img.exe create -f qcow2 hd.qcow2 1G, the output file size is rather big comparing to your home.qcow etc. but at this moment it's acceptable, because I thought it's qcow2 not qcow, and I can adjust the output size with cluster_size option. What unacceptable is, after I download a small file within the VM, the image size increased to dozens of MBs from several hundred KBs. But your image files don't act like this, after download a file, the size of "home.qcow" only increase several KBs.

So I wonder if you could teach me on how you formatted the disk image, or what did you do to make it so lean?

Thanks in advance!
