[Qemu-devel] [PULL 5/6] migration: show average throughput when migration finishes

[Juan Quintela]

From: Peter Lieven <address@hidden>

currently the value of the throughput field contains whatever
was the last calculated throughput shortly before the migration
finished.

This patch updates the post migration contents of the field to
the average throughput.
