The no_migrate save state flag is currently only checked in the last phase of migration. This means that we potentially waste a lot of time and bandwidth with the live state handlers before we ever check the no_migrate flags. The error message printed when we catch a non-migratable device doesn't get printed for a detached migration. And, no_migrate does nothing to prevent an incoming migration to a target that includes a non-migratable device. This attempts to fix all of these. One notable difference in behavior is that an outgoing migration now checks for non-migratable devices before ever connecting to the target system. This means the target will remain listening rather than exit from failure. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
