Troubleshooting
Problem
The default virtual machine interface (VMI) kernel does not pass the clock=pmtmr parameter to the kernel. However, if you pass the clock=pmtmr boot parameter to a virtual image with a VMI kernel, you might see a performance degradation.
Symptom
Diagnosing The Problem
You can check for a performance degradation with standard performance bench-marking software, such as SPECjAppServer.
Resolving The Problem
Using an editor, such as vi, open the /boot/grub/menu.lst file and remove the clock=pmtmr boot parameter on the kernel command line for the desired VMI kernel.
Example:
/boot/grub/menu.lst
