virDomainGetJobStats is able to report statistics of a completed migration, however to get usable downtime and total time statistics both hosts have to keep synchronized time. To provide at least some estimation of the times even when NTP daemons are not running on both hosts we can just ignore the time needed to transfer a migration cookie to the destination host. The result will be also inaccurate but a bit more predictable. The total/down time will just be at least what we report.https://bugzilla.redhat.com/show_bug.cgi?id=1213434 Signed-off-by: Jiri Denemark <jdene...@redhat.com> --- include/libvirt/libvirt-domain.h | 23 ++++++++++++++++++++++- src/qemu/qemu_domain.c | 15 +++++++++++++++ src/qemu/qemu_domain.h | 9 +++++++++ src/qemu/qemu_migration.c | 26 +++++++++++++------------- tools/virsh-domain.c | 16 ++++++++++++++++ 5 files changed, 75 insertions(+), 14 deletions(-) diff --git a/src/qemu/qemu_domain.h b/src/qemu/qemu_domain.h index 6bea7c7..1b93f7d 100644 --- a/src/qemu/qemu_domain.h +++ b/src/qemu/qemu_domain.h @@ -100,9 +100,18 @@ struct _qemuDomainJobInfo { virDomainJobType type; unsigned long long started; /* When the async job started */ unsigned long long stopped; /* When the domain's CPUs were stopped */ + unsigned long long sent; /* When the source sent status info to the + destination (only for migrations). */ + unsigned long long received; /* When the destination host received status + info from the source (migrations only). */ /* Computed values */ unsigned long long timeElapsed; unsigned long long timeRemaining; + long long timeDelta; /* delta = sent - received, i.e., the difference
