Hi, I recently upgraded from xen 3.2 running a 2.6.18 domU to xen 3.3 running a 2.6.27 pvops domU. Dom0, domU and hypervisor is 64-bit. In the old configuration, the time on the domU's were in sync with the dom0. This made keeping the correct time easy by running a single instance of ntp on the dom0 and all the domU's would follow. In the new configuration though, the domU's seem to have their own time which drifts relative to the dom0 and the other domU's. The behaviour in the 2.6.18 kernel could be changed via /proc/sys/xen/independent_wallclock, but the 2.6.27 kernel seems to have no such option. Is there a kernel option (maybe for an RTC driver?) that I need to compile in to restore the old behaviour or do I now need to run ntp in every domU? Cheers, Brad _______________________________________________ Xen-users mailing list Xen-users@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-users
