Fast Clock on WinXP VMWare on Linux
Tim Morrow made a post outlining how to fix the problem here.
I’ll outline a more comprehensive way to do it and for my own archive here.
This apparently only affects dual core Intel procs, if that’s not the case please let me know so I can make the correction.
First we need to make sure we have cpufrequtils installed:
This line will run the cpufreq-info command and pull out just what we need:
And this is what I got back on my system:
hardware limits: 1.60 GHz - 1.87 GHz
Now we’ll open the vmware config file with our favorite editor. Do note that we’ll have to do this as sudo or we can’t edit the file:
To get the value we’ll add to the config file just take your GHz and convert to Hz: multiply by 1,000,000.
Add the following lines to the end:
host.noTSC = TRUE
ptsc.noTSC = TRUE
Restart your VMWare if it’s already running and you should be all set! Thanks again to Tom for first posting the howto!
