I am now trying to add one more state, something like MIGRATION_STATUS_FINISHING. It would mean that CPUs are stopped. Can you explain me migration code a bit? Where is iteration loop, and where are CPUs stopped? I am looking at migration.c but cannot say that i understand some good portion of it. :) Kind regards, Pavel Fedin Expert Engineer Samsung Electronics Research center Russia
