The problem is, that when using a qcow2 image, the OS reports the disk size to be like 192k, not 10G. This also happens on Debian jessie and using different partitioning tools like parted, cfdisk or looking at /proc/partitions. Therefore it's not the fault of setup-storage or parted.
It can be fixed by adding "-o preallocation=metadata" to the qemu-img call when creating the image. Then the OS reports the correct size, but the image still only needs like 1MB of disk space. It will grow, the more you write to this disk image. IMO this bug can be closed. -- regards Thomas
