This needs to be separate from 034 because we can only support qcow2 in this test case for multiple reasons: We check the allocation status after write_zeroes with 'qemu-img map' and the optimised behaviour that produces zero clusters is only implemented in qcow2; second, the map command returns offsets that are qcow2 specific; and finally, we also use 512 byte clusters which aren't supported for formats like qed.
