Subject: [Qemu-devel] [PATCH v7 23/42] MIGRATION_STATUS_POSTCOPY_ACTIVE: Add new migration state
Date: Tue, 16 Jun 2015 11:26:36 +0100 [thread overview]
Message-ID: <1434450415-11339-24-git-send-email-dgilbert@redhat.com> (raw)

From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
'MIGRATION_STATUS_POSTCOPY_ACTIVE' is entered after migrate_start_postcopy
'migration_postcopy_phase' is provided for other sections to know if
they're in postcopy.
