The clock in my Gutsy guest OS would run much faster than my host computer. The problem is caused by computers using dynamic CPU speed technology.

Here is a workaround I have found:

  1. Edit your /etc/vmware/config

    sudo vim /etc/vmware/config

  2. Add the following line to /etc/vmware/config

    host.cpukHz = x
    host.noTSC = TRUE
    ptsc.noTSC = TRUE

    x = Max CPU speed in kHz (i.e. 2GHz CPU = 2000000)

  3. Install VMware Tools in Guest OS
  4. Verify that Time synchronization between the virtual machine and the host operating system is selected
