Management apps like libvirt don't know to pay attention to stderr unless there is a non-zero exit status.
* migration.c (process_incoming_migration_co): Exit with non-zero status on failure. Signed-off-by: Eric Blake <ebl...@redhat.com> --- Noticed while reviewing: https://lists.gnu.org/archive/html/qemu-devel/2013-04/msg03293.html and it seems blatant enough to fix now, rather than waiting for Pavel's series to stabilize. Side note: libvirt explicitly forbids all use of exit({0,1}), and instead encourages exit(EXIT_{SUCCESS,FAILURE}), precisely because it makes it harder to slip in unintentional successful exits. migration.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/migration.c b/migration.c index 3b4b467..3eb0fad 100644 --- a/migration.c +++ b/migration.c @@ -99,7 +99,7 @@ static void process_incoming_migration_co(void *opaque) qemu_fclose(f); if (ret < 0) { fprintf(stderr, "load of migration failed\n"); - exit(0); + exit(EXIT_FAILURE); } qemu_announce_self(); DPRINTF("successfully loaded vm state\n"); -- 1.8.1.4
