Re: [Xen-devel] Xen 3.1.2 domU clock goes out of sync

I wonder if dom0 has remembered some ntp-derived adjustment values despite

Well... in the example in my first letter dom0 was booted without ntpd and after 2+ days its clock offset was only -0.438055 while domU had drifted far away. In that case there was no adjustment values to remember.

So... running ntpd in dom0 is a good idea. :-)

I don't question that. But I wonder, isn't domU clock supposed to be always in sync with dom0, with or without ntpd? Or how exactly does ntpd in dom0 affect domU clock?
