Hi Priya: If you are using NTP, then shutdown the NTP service on all DomU and restart it on Dom0 only. Regards, Tanuj Bansal -----Original Message----- From: xen-users-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-users-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Priya Sent: Wednesday, July 01, 2009 8:55 PM To: xen-users@xxxxxxxxxxxxxxxxxxx Subject: [Xen-users] Xen time drift issues Hello everyone! I been observing some peculiar time drift on my Xen domains (dom0 and domUs). The time (as returned by timeofday) on my domains drifts at an almost steady rate from the real time ( as read from the time stamp counter ). The drift is so constant that it makes me think there should be some simple explanation for it in the way Xen keeps time. Some info about my set up: guest OS: ubuntu independent_wallclock is set to default 0 on all domains no NTP synchronization The drift is around 50 microseconds / second on all the domains. Has anyone else observed this? If anyone can point me to some documentation that explains this behavior, that would be great! Good day! _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users |
