2014-02-26 Thread Andrew Jones
commit 0061d53daf26f introduced a mechanism to execute a global clock update for a vm. We can apply this periodically in order to propagate host NTP corrections. Also, if all vcpus of a vm are pinned, then without an additional trigger, no guest NTP corrections can propagate either, as the current
