Or paste a hexdump -Cv of the first few hundred bytes of each file here. AFAICT only qcow v3 actually supports compression; I wonder if the qemu-img file is in fact a "sparse" image managed by qemu rather than the filesystem. ref: https://git.qemu.org/?p=qemu.git;a=blob;f=docs/interop/qcow2.txt -- You are receiving this mail because: You are the assignee for the bug.
