>From what I understood about this issue it would appear that CP decides a guest isn't 'really idle' if it has any CCW I/O currently in progress. However, due to the way network I/O is done, there is always a READ CCW outstanding on LCS/CTC devices to allow for incoming packets to get received. (With QDIO there are apparently similar issues.) Thus, CP will never drop guests from queue that have any (non-IUCV) network connection open, no matter what Linux does. This is really for the VM folks to look at ... On the other hand I'm not sure that even with the timer patch and without network connections you can get a Linux guest to go 'idle enough' to drop completely out of queue; there's user space daemons that get periodically active and the like. >One other possible symptom is that your system >load never goes below 1.00.

This does not indicate there is really load on the system, it is the calculation of the load factor that is broken for some reason. B.t.w. does this symptom change if you switch the timer patch on/off? Bye, Ulrich -- Dr. Ulrich Weigand [EMAIL PROTECTED]
