VMWare guests run slowly on Linux 2.6 Host

If you are experiencing slow guest OS's when running on Linux with a 2.6 kernel, then you have 3 options:

1) Turn off ACPI support completely with the following Grub/Lilo boot argument:

acpi=off

2) Unload the processor and thermal ACPI modules before starting VMWare server/workstation/player:

rmmod thermal
rmmod processor

3) Don't compile ACPI processor support into the kernel:

# CONFIG_ACPI_PROCESSOR is not set

-> Power management options (ACPI, APM)
 -> ACPI (Advanced Configuration and Power Interface) Support
  -> ACPI Support (ACPI [=y])
   -> Processor [=n]
