At least with live block commit, it is possible to have a block job that reports 0 status: namely, when the active image contains no sectors that differ from the backing image it is being committed into [1]. I'm not sure if that represents a qemu bug, but it leads to weird virsh output where 'virsh blockjob $dom vda' has no output during a no-op commit job. It appears that the special case for a zero total was first introduced for migration, where it does sort of make sense (when we do storage migration, the job is broken up into two pieces where the first half of migrating storage has no clue what the total length of the second phase will be, and where qemu migration always reports a non-zero total length but only once we complete the first phase to start actual migration), but it doesn't seem to make sense for any of the block jobs.
