If you are at the latest levels and your Linux tools already show the steal time... that probably holds for the tools where IBM was interested to make the enhancements. ESALPS has been doing this since SLES7 or so. You would be surprised how many people have good reasons not to run the latest levels yet. And when you have ruled out excessive CP overhead for that virtual machine. But the next question often is *why* - something that can be answered with the VM monitor data (and again the Linux detail from those other virtual machines).
