From 4886a1bcb7d7a88da02eefb0f33327c613ac52a3 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Thu, 5 Nov 2015 18:10:56 +0000 Subject: migrate_start_postcopy: Command to trigger transition to postcopy Once postcopy is enabled (with migrate_set_capability), the migration will still start on precopy mode. To cause a transition into postcopy the: migrate_start_postcopy command must be issued. Postcopy will start sometime after this (when it's next checked in the migration loop). Issuing the command before migration has started will error, and issuing after it has finished is ignored.
