Virtual Machine Clock Reports Time Unpredictably on Multiprocessor Systems (2041)
This problem can occur on some 64-bit AMD multiprocessor (including multicore) systems. If you run VMware products on one of these systems and the clocks in your virtual machines are performing unpredictably, VMware recommends you apply the workaround described below.
- In your system's BIOS setup windows, look for settings labeled PowerNow or Cool'N'Quiet, and disable them.
- If you are running a Linux host operating system, look for a system daemon or applet called cpufreqd, cpuspeed, powernowd, cpudyn, speedy, or cpufreq, and disable it. For example, on some systems the command service cpuspeed stop might work. The instructions to disable the daemon or applet found on your system vary. Refer to your system's documentation for more information.
Note: If you are running Windows XP Service Pack 2 as the host operating system on a multiprocessor 64-bit AMD host that supports processor power management features, you also need to apply the hotfix described in Microsoft knowledge base article 896256 at http://support.microsoft.com/?id=896256. According to this Microsoft knowledge base article, the hotfix is needed for the following operating systems:
- Microsoft Windows Server 2003, Standard and Enterprise x64 Editions
- Microsoft Windows XP Service Pack 2, when used with Microsoft Windows XP Home and Professional Editions
- Microsoft Windows XP Tablet PC Edition 2005
