I have a VM with 2 virtual CPUs. When I run two multi-threaded java proceses the total CPU utilization in top exceeds 200%. In fact its closer to 800%.

I thought that %CPU was the percentage utilization of one core, and that a process on a two core box couldn't exceed 200 %CPU. Am I wrong?

Does it make any more since when using the -H option (Press Shift-H while running), to show threads? Then see the "What to look for from the top -H output" from this IBM link.
