Firstly, it's parameterised, so that you can change the number of packets and the gap between them; the number can be set to 0 to disable announce completely. Secondly, you can force an announce by a qmp or hmp command at any time. This is useful if you need the guest to do an announce for a different reason; for example if the management layer has just juggled some bonding configuration around. The packet creation and timing also moves to net/ from migration/ The previous set was: https://lists.gnu.org/archive/html/qemu-devel/2017-05/msg05594.html Dave Dr. David Alan Gilbert (9): net: Introduce announce timer migration: Add announce parameters virtio-net: Switch to using announce timer migration: Switch to using announce timer net: Add a network device specific self-announcement ability virtio-net: Allow qemu_announce_self to trigger virtio announcements qmp: Add announce-self command hmp: Add hmp_announce_self tests: Add a test for qemu self announcments hmp-commands.hx | 14 ++++ hmp.c | 33 ++++++++ hmp.h | 1 + hw/net/trace-events | 8 ++ hw/net/virtio-net.c | 69 ++++++++++++---- include/hw/virtio/virtio-net.h | 4 +- include/migration/misc.h | 12 +-- include/net/announce.h | 41 ++++++++++ include/net/net.h | 2 + include/qemu/typedefs.h | 2 + include/sysemu/sysemu.h | 2 - migration/migration.c | 103 +++++++++++++++++++++++- migration/migration.h | 4 + migration/savevm.c | 72 +---------------- migration/trace-events | 1 - net/Makefile.objs | 1 + net/announce.c | 141 +++++++++++++++++++++++++++++++++ net/trace-events | 4 + qapi/migration.json | 56 ++++++++++++- qapi/net.json | 43 ++++++++++ tests/Makefile.include | 2 + tests/test-announce-self.c | 83 +++++++++++++++++++ tests/test-hmp.c | 1 + 23 files changed, 595 insertions(+), 104 deletions(-) create mode 100644 include/net/announce.h create mode 100644 net/announce.c create mode 100644 tests/test-announce-self.c --=20 2.20.1
