NTP time sync not working in a DOMU Centos 5.5 server

centos5ntpntpdxen

I have a Xen Centos 5.5 server with ntpd working in virtual server.

NTP time sync seems not working.

I have disabled any firewall.

my grep -i ntpd /var/log/messages output:

By default the time of (pv) DomUs is linked against the time of the Dom0. So get your time right on the Dom0 and don't bother about ntp on the (para-virtualized) DomUs.
