yeah, i'm already doing that, I was just saying, it *seemed* like they
were getting their time from domain0, and weren't actually changing their
own clocks in accordance with syncing with the same ntpd server.
especially since they're all off by exactly the same amount ... and
running ntpdate doesn't seem to have any effect whatsoever?

Maybe i'm way off

So, from what it looks like (on my servers and the docs), all my domains

the dom0 looks good. However, All of the domains are 1.5 seconds off, and

.768 seconds off (off of the server i'm ntping to) , but both domO's are
withing (.02) and seem to narrow in as NTP is supposed to.
So, question is, 1) what is going on here, and 2) can anything be done
about it?
Are you using OpenNTPD by any chance?
My machines suffered from inaccurate clocks in DomU's, even though the
clock was very accurate in Dom0. Switching to regular ntpd solved this,
DomU immediately used the correct time shortly after starting ntpd.

Andrew,
Please remember, you allways shoult treat each virtual machine
like a completely separated host! So far, you shoul configure ntpd
to get time from -possibly- the same host as you dom0 is getting
time. Try that. It won't hurt :) And I bet you will feel happy with
the result :)
