Hi, coming into this late, but I have been very successful with the following solution: 1. make sure all ESX hosts are syncing time via NTP with a reliable source 2. disable NTPD in all guests 3. set each guest to sync time via VMware tools by setting tools.SyncTime=TRUE 4. in each guest, on the kernel line in grub.conf, set clock=pit and reboot That has been a bulletproof method for me with over 70 linux guests. re: http://www.vmware.com/pdf/vmware_timekeeping.pdf HTH, Josh Miller - RHCE, VCP -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
