Re: [Xen-users] time synchronization problem (using NTP)



Hi Thomas,

As far as my experience shows, none of the ntp / independent_wallclock combinations work. We got the same problem here with xen 3.0.2 and kernel 2.6.16. It looks like ntpd can't set the time in DomUs with independent_wallclock set to 1 but the DomUs aren't using the exact time of Dom0 with independent_wallclock set to 0.

I'm running 2.6.16-2-xen-k7 with XEN 3.0 on both Dom0 and DomUs. A cron job on Dom0 runs "ntpdate ptbtime1.ptb.de" every night (shifting the time some milliseconds). All DomUs are perfectly in sync. /proc/sys/xen/independent_wallclock = 0 in all DomUs.
