VMware recommends using NTP and turning off VMware Tools periodic time synchronization in the guest. To turn this off, there are three options:
- Set tools.syncTime = "False" in the configuration file (.vmx file) of the virtual machine.
- Deselect Time synchronization between the virtual machine and the host operating system in the VMware Tools toolbox GUI of the guest operating system.
- Run the vmware-guestd --cmd "vmx.set_option synctime 1 0" command in the guest operating system.

Notes

64bit | RHEL 5.4 and later | No additional kernel parameters. | |
32bit | RHEL 5.4 and later | No additional kernel parameters. | |
64bit | RHEL 5.3 | notsc divider=10 | |
32bit | RHEL 5.3 | divider=10 clocksource=acpi_pm | |
64bit | SLES 10.2 and later | No additional kernel parameters. | |
32bit | SLES 10.2 and later | Use a VMI enabled kernel. |
You now want to make sure that NTP is configured correctly for your environment.
The following is a sample /etc/ntp.conf :
server ntp1.somedomain.org
server ntp2.somedomain.org
restrict 127.0.0.1
restrict default nomodify nopeer
driftfile /var/lib/ntp/drift
