The intermediate block streaming code was finished and ready to be merged about half a year ago. Unfortunately there were conflicts with other changes that were happening at the same time so it had to be rolled back. Here's the latest version of the series: https://lists.gnu.org/archive/html/qemu-devel/2015-06/msg05754.html And here's a recent summary of the problems that prevent it from being merged: https://lists.gnu.org/archive/html/qemu-block/2015-12/msg00180.html My plan is to continue working on it.
