qemu-img map? 1. We need to fix the bug somehow 2. We need to fix comment about different block-status flags, as it really lacks information of what actually "DATA" means (together with *file). And what finally means "allocated", can you define it precisely? 3. Fix nbd-server to be closer to NBD spec about block-status I made several tries to imagine [1] and [2] but never succeeded.. -- Best regards, Vladimir
