charset="utf-8" Writing zeroes to a qcow2 v2 images without a backing file results in an unallocated cluster as of 61b3043965. 197 has a test for COR-ing a cluster on an image without a backing file, which means that the data will be zero, so now on a v2 image that cluster will just stay unallocated, and so the test fails. Just force compat=3D1.1 for that particular case to enforce the cluster to get allocated.
