Re: [libvirt] [PATCH] qemu: Propagate QEMU errors during incoming migrations

When QEMU fails during incoming migration after we successfully started it (i.e., during Perform or Finish phase), we report a rather unhelpful message Unable to read from monitor: Connection reset by peer We already have a code that takes error messages from QEMU's error output but we disable it once QEMU successfully starts. This patch postpones this until the end of Finish phase during incoming migration so that we can report a much better error message: internal error: early end of file from monitor: possible problem: Unknown savevm section or instance '0000:00:05.0/virtio-balloon' 0 load of migration failed https://bugzilla.redhat.com/show_bug.cgi?id=1090093 Signed-off-by: Jiri Denemark <jdenemar(a)redhat.com&gt; --- src/qemu/qemu_migration.c | 2 ++ src/qemu/qemu_monitor.c | 7 ++++++- src/qemu/qemu_process.c | 6 ++++-- 3 files changed, 12 insertions(+), 3 deletions(-)
