Hi all,

For some reason probably obvious that I am missing, my domU's aren't updating their time properly. On dom0 I can run 'ntpdate tick.redhat.com' and it properly changes the clock:

root@vsh02:~# ntpdate tick.redhat.com
8 Dec 12:59:44 ntpdate[27362]: step time server 66.187.233.4 offset -186.959214 sec
root@vsh02:~# ntpdate tick.redhat.com
8 Dec 12:59:51 ntpdate[27365]: adjust time server 66.187.233.4 offset 0.000176 sec

When I run the same on a given domU though, it *looks* like it's updating, but doesn't actually:

root@sql01:~# ntpdate tick.redhat.com
8 Dec 13:10:08 ntpdate[1148]: step time server 66.187.233.4 offset -655.452750 sec
root@sql01:~# ntpdate tick.redhat.com
8 Dec 13:10:43 ntpdate[1373]: step time server 66.187.233.4 offset -655.457543 sec

   Notice that it doesn't seem to relate to dom0's skew.

   Any tips?

Thanks!!

Madi

I ran into this problem as well. Once I updated dom0 and
shutdown/started the domU it worked again.

Hrm, I need a way to keep the domUs update without a reboot... Did you come across any clues as to what/where the problem was?

Madi
