Time synchronization problems inside guest - Guest time moving ahead

$

As suggested I am creating a new thread.  I am having similar issues as stated in this thread: http://communities.vmware.com/thread/130979?tstart=0

 

I have a WinXP SP2 guest who's time is moving ahead by approximately 10-30 minutes per hour.  I have tried all of the suggestions included in the whitepaper "Timekeeping in Virtual Machines" that relate to my problem of time jumping ahead (http://www.vmware.com/pdf/vmware_timekeeping.pdf).

 

It appears that I have the problem stated in point 5 on page 23 of the whitepaper - "Guest time runs faster than real time."  I have a 2.4GHz Intel Core2 Quad Core chip, but the KHZEstimate shows a 1.6GHz processor:

 

[root@cinshrfluxws01 /tmp]# grep "model name" /proc/cpuinfo 
model name      : Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz

[root@cinshrfluxws01 /tmp]# grep -i KHZ /home/vmware/sfg-xp/vmware.log 
Mar 10 09:54:13: vmx| KHZEstimate 1600000
Mar 10 09:54:13: vmx| VMMon_GetkHzEstimate: Calculated 2394135 kHz

 

The whitepaper suggests rebooting the host to resolve the issue.  I have several times and it has not resolved it.

 

As a test, I created a minimal CentOS 5 guest and it appears to be exhibiting the same behavior - time moves ahead in the guest by 10-15 minutes per hour if I don't have ntpd enabled.

 

Here are the details of my setup:

 

Dell OptiPlex 755 Host

Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz

VT turned on

4GB RAM

Intel Matrix Storage RAID (uses /dev/mapper)

2 250GB WD2500AAJS-75VWA0 hard drives in RAID1

Fedora 8 i386 (not x64) Host OS with all updates as of yesterday

Linux Kernel 2.6.24.3-12.fc8

 

VMware Server 1.0.4 build-56528

 

WinXP SP2 Guest with all updates as of yesterday

VMware Tools installed in guest

VMware Tools Time synchronization turned off

 

CentOS 5 guest

Linux kernel 2.6.18-8.1.15.el5

 

I turned on verbose TimeTracker messages and the vmware.log file for both the WinXP and CentOS guests in question are attached.  vmware-0 is XP; vmware-1 is CentOS.

 

Any help is appreciated.
