Fixing your VMWare’s guest clock

less than 1 minute read

If you’re using VMWare on a variable-speed processor (like all most modern cpu’s these days) you might have noticed that sometimes the guest OS runs a lot faster (causing the guest clock to run faster and all kinds of weird effects).

The fix for that is easy, and specified in this knowledgebase article:

Add to /etc/vmware/config the following lines:
<br /> host.cpukHz = 1700000<br /> host.noTSC = TRUE<br /> ptsc.noTSC = TRUE<br />

replacing 1700000 with the actual top speed of your processor. Et voila, runs better ;)
