Hi everyone, I have been struggling with having the clock of Linux VM's (including CentOS 4.6 and 5.1) running very fast under VMWare, no matter what I have tried. My platform: - AMD Turion X2 TL-60 - AMD 690 chipset with integrated Radeon x1250 (probably doesn't concern in this case) - Windows Vista Ultimate x64, all Windows Update patches loaded (no SP1 yet) - 4GB RAM - VMWare Workstation 6.0.2 - BIOS has no options to disable power management, etc. On my host PC - C:\ProgramData\VMware\VMware Workstation\Config.ini, put in host.cpukHz = "2000000", host.noTSC = "TRUE", ptsc.noTSC = "TRUE" - AMD's dual core optimizer loaded On CentOS 5.1 VM - use kernel options "noapic nolapic nosmp clocksource=acpi_pm" - use "divider=10" option in the regular kernel - try the vm version of the kernel in centos-plus with the same kernel options in first line No matter what I try, the CentOS clocks are still fast - at a rate of almost 2 seconds for every 1 real second. What other things I can do in order to fix this? M. Chan
