To prevent guest clocks from running too quickly, specify the correct maximum host CPU speed in your global configuration file, /etc/vmware/config. If this file exists, edit it with a text editor, adding the lines described below. The file may not exist. If it does not exist, create it as a plain text file.
The example presented here assumes that the host computer has a maximum speed of 1700MHz. The first line is the most important one. It should be your host computer's maximum speed in kHz -- that is, its speed in MHz times 1000, or its speed in GHz times 1000000. To find your actual host's maximum CPU speed, run cat /proc/cpuinfo and look for the line cpu MHz, which is your host's maximum CPU speed. Add the following lines to your global configuration file:
host.cpukHz = 1700000
host.noTSC = TRUE
ptsc.noTSC = TRUE
