Does the very short answer "the domU time is calculated from a counter that is based of the dom0 uptime measured in nanoseconds - unless the domU is using clocksource=jiffies" make it clearer? Actually I'm not sure I got it 100% right on a technical point of view now (tired, zzzzz), but the basic meaning is right: You might be seeing a corner case where nothing but a dom0 reboot would help. But I think you can also change the domU clock source at run-time, so that might be preferrable right now. My "datacenter" also didn't set the system clocks to UTC after some maintenance. I resorted to a 2hour-downtime for the database boxes. Not great. Time for yet another nagios check ;) Florian _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
