Herne" This patch set provides a new method for throttling a vcpu and makes use of said method to dynamically increase cpu throttling during an autoconverge migration until the migration completes. This method ensures that all migrations will eventually converge. The method used here for throttling vcpus is likely not the best. However, I believe that it is preferable to what is used for autoconverge today. This work is related to the following discussion: https://lists.gnu.org/archive/html/qemu-devel/2015-03/msg00287.html Jason J.
