Re: [Xen-users] NTP time issues DomU's
don't the DomU's just get their time from DomO? Ie. ... even if they
weren't running ntp they'd always be synced with whatever DomO thought
about system time?
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
won't ntp themselves on, also, an identical server, all the domains are
.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.
