Do not use ntp to sync time on the guest OS. Sync using ntp on the HOST, and then use the vmware tools to sync in the guest. I have pursued this issue many times, and that is the best answer. Then update your kernel boot parameters and add: clock=pit # for kernels less than 2.6 OR clocksource=pit # for kernels 2.6.16 and later There is far more than you ever wanted to know about vmware time syncing here: http://www.vmware.com/pdf/vmware_timekeeping.pdf _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
