I'm trying to keep correct time on both machines, on dom0 and domU.. I
have installed OpenNTPd and made it to synchronize with local ntp
server. But, it works on dom0, but does not on domU..

After some googling, I found that domU have no own time, so it should
be always in sync with dom0 time (unless you change it through
/proc/sys/xen/independent_wallclock). So I just shut down ntp server
in domU and let ntp server in dom0 do it's work.

At the moment, clock in dom0 is about 8 minutes ahead of real time,
and I see in logs that ntp server is slowly correcting it (something
about half a minute per day).. But I don't see a clock in domU
changing.. There is a difference between what date says on these

It seems that clock in domU is not updated.. By the way,
independent_wallclock is set to 0, and I cannot set time through "date
-s" in domU..

Any suggestions?

P.S. I'm running xen-2.0.7-testing on 2.6.12 kernel.
