Re: [libvirt] [PATCH 3/3] Wire up virDomainMigrateSetSpeed into QEMU driver

Enhance the QEMU migration monitoring loop, so that it can get a signal to change migration speed on the fly * src/qemu/qemu_domain.h: Add signal for changing speed on the fly * src/qemu/qemu_driver.c: Wire up virDomainMigrateSetSpeed driver * src/qemu/qemu_migration.c: Support signal for changing speed --- src/qemu/qemu_domain.h | 2 + src/qemu/qemu_driver.c | 51 ++++++++++++++++++++++++++++++++++++++++++++- src/qemu/qemu_migration.c | 11 +++++++++ 3 files changed, 63 insertions(+), 1 deletions(-) diff --git a/src/qemu/qemu_domain.h b/src/qemu/qemu_domain.h index ebb2050..8258900 100644 --- a/src/qemu/qemu_domain.h +++ b/src/qemu/qemu_domain.h @@ -45,10 +45,12 @@ enum qemuDomainJobSignals { QEMU_JOB_SIGNAL_CANCEL = 1 << 0, /* Request job cancellation */ QEMU_JOB_SIGNAL_SUSPEND = 1 << 1, /* Request VM suspend to finish live migration offline */ QEMU_JOB_SIGNAL_MIGRATE_DOWNTIME = 1 << 2, /* Request migration downtime change */ + QEMU_JOB_SIGNAL_MIGRATE_SPEED = 1 << 3, /* Request migration speed change */
