You can always have a cron run ntpdate every hour... Not the cleanest solution but it''s a solution.

Thanks for your answer, i have alredy implemented this solution. I was asking if do someone know a better solution and how is it possible that a DomU, that is running from one year, suddenly start to lose 30 minutes a day Regards, Francesco Da: Antoine Benkemoun [mailto:antoine.benkemoun@gmail.com] Inviato: martedì 8 settembre 2009 10.16 A: Francesco Gallo Cc: Xen User-List Oggetto: Re: [Xen-users] DomU clock problems You can always have a cron run ntpdate every hour...

You only need ntp on dom0, and domUs will follow. The alternative, set /proc/sys/xen/independent_wallclock to 1 and run ntp on domU. If this is a HVM dom0, running ntp on domU is your friend. Also, check http://tuttodebian.blogspot.com/2008/05/xen-clocksource0-time-went-backwards.html to see if your system experience similar symptoms. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
