If not, what do you use for a realtime performance monitor? It could be something as simple as a virtual machine that's unhappy about something and looping. Anything look out of the ordinary on VM/RTM? -Mike -----Original Message----- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of O'Brien, Dennis L Sent: Tuesday, June 17, 2008 1:32 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: zVM 3.1 at 100% CPU after z9 upgrade Ismael, My first guess is that z/VM 3.1 and/or z/VM 5.1 need PTF's for z9 support. z/VM 3.1 has been long out of support, so no such PTF exists. z/VM 5.1 is also out of support, but if it was supported when z9's were introduced, there would be a support PTF for it. If there is such a PTF, did you apply it? If it exists, you should still be able to get it from IBMLink. Dennis O'Brien "Don't worry about biting off more than you can chew.

We have hit a wall. I know this is mainly a zLinux forum, but I know there's a lot of VM talent in here. We are running production work on zVM 3.1 (don't ask why) running 2nd level under zVM 5.1 . Things has been running good for more than a year until this change: Hardware was upgraded from z990 to z9 . Now guest zVM3.1 is running 100% cpu; 1st level zVM 5.1 is running 100% CPU. We can't go back to z990 because many more zOS are running in other LPARs. Since 3.1 is out-of-support, no IBM help. Please, please help.
