[Qemu-devel] [Bug 1662050] Re: qemu-img convert a overlay qcow2 image into a entire image
@Eric Blake, I used virt-sparsify to sparsify the qcow2 overlay image. As you said, the actual disk usage is minimized and the apparent file size is unchanged.It is very valuable for me, because it means that my disk can hold more files. But we need to be careful when transfer the sparse qcow2 overlays. Because some tools do not support sparse file and will convert it into a common file,for example, scp. And I doubt what will happen when transfer sparse files between different file systems. So I want to use qemu-img to convert the sparse qcow2 overlay into common file. If this was feasible, the holes in the sparse overlay will be removed and the above problems will disappear. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1662050 Title: qemu-img convert a overlay qcow2 image into a entire image Status in QEMU: Incomplete Bug description: I have a base image file "base.qcow2" and a delta qcow2 image file "delta.qcow2" whose backing file is "base.qcow2".
