I've been waiting for some performance person to chime in on what I perceive as a disparity, but it has not happened. So I will ask the question - Aren't we talking about two different technologies here - cpuplugd and CMM/VMRM? Yes, the new Virtualization Cookbooks describe cpuplugd in the section "Utilizing the cpuplugd service". This was based on presentations from Hans-Joachim Picht, et al, but it does not involve CMM and VMRM. In previous versions of the book there were sections on those, but it was agreed that they should be removed - probably the references to loading the cmm module at Linux boot time should also be removed (perhaps this was the source of the confusion). So I believe the answer to the original question is - you don't need to configure CMM and VMRM for the cpuplugd service to work. That section should pretty much stand on it's own. And please, could we have a bit less FUD without really digging into the question? Thanks. "Mike MacIsaac" <mike...@us.ibm.com> (845) 433-7061
