...e'd be better off with a separate > read-through once writing is complete. In my mind I'm wondering if there's any mathematical result that lets you combine each hash(block_i) into the final hash(block[1..N]) without needing to compute the hash of each block in order. (This is what blkhash solves, but unfortunately the output isn't compatible with standard hashes.)

https://github.com/kubevirt/containerized-data-importer/issues/1520 Hi Eric, We had a question from the Kubevirt team related to the above issue. The question is roughly if it's possible to calculate the checksum of an image as an nbdkit filter and/or in the qemu block layer. Supplemental #1: could qemu-img convert calculate a checksum as it goes along? Supplemental #2: could we detect
