Hi,

What I did:
I disabled independent_wallclock, removed all ntp-packages (ntpdate, ntp).

Now I found the following strange behavior:
My DomU-time, compared with Dom0-time, is running away (+1s / 30s).

I also tried to change the clocksource to "pit|tsc", but after:

- echo -n 'pit' > current_clocksource
- echo 'pit' > current_clocksource
- echo -n 'tsc' > current_clocksource
- echo 'tsc' > current_clocksource
- Bootparam: clocksource=pit|tsc

clocksource was still jiffies.

I also compiled 2.6.18.8-xen (linux-2.6.18-xen.hg) again, nothing changed.

I tried to set "timermode=0" and/or "hpet=1", nothing changed.

Thanks for any hints,
Fabian
