[Qemu-devel] [Bug 1399191] Re: Large VHDX image size
Hi Jan, ls -l returns the length of the file; qemu-img info prints the size of the file (just like du does). Those are not necessarily the same, as you can see. On modern filesystems, files can have holes in them which do contribute to the file length, but which do not use any space on disk and thus do not contribute to file size. Besides using qemu-img, you can obtain the actual disk usage (the file size) by using du or ls --size (-s for short).
