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
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
