vdsm hosts clock sync

Hi, I want to add a new feature that reports migration actual downtime (the time that the VM was inaccessible to the user). Libvirt reports that information but the vdsm hosts need to be in sync by clock time. I can measure the ping for NTP server an report back to the user if the ping is too long (more then ~100ms or so) - a way to do that is via ntpstat shell command. The NTP delay can be report back via vdsStats and can be performed every few hours or so. Anyone knows of a better way that we can sync between hosts? Thank you, Shahar Havivi.

It would be so cool if you would bother to open such RFEs at the upstream project (ovirt), instead of RHEV, so the whole community can be a part of this process. I don't get notifications for these RHEV downstream RFEs but I get them for ovirt. Thanks -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.
