With this our tests pass with qemu-nbd build with Eric patch: https://gerrit.ovirt.org/c/ovirt-imageio/+/115197/1/daemon/test/client_te... We may need to use qemu:joint-allocation only for qcow2 images, and base:allocation for raw images, because allocation depth reporting is not correct for raw images. Since we control the qemu-nbd in both cases this should not be an issue. But it would be better if allocation depth would work for any kind of image, and we always use qemu:joint-allocation. Nir
