Steal would be reported by the guests. For the nodes you can report "guest" though I'm not sure if this is part of RHEL yet. This is what it looks like on a Fedora 15 system (man mpstat): %steal Show the percentage of time spent in involuntary wait by the virtual CPU or CPUs while the hypervisor was servicing another virtual processor. %guest Show the percentage of time spent by the CPU or CPUs to run a virtual processor.

Dennis - so you only mean reporting this to engine? can you please explain the use case? (as for when - depends on amount of interest or patches actively pushed = for it) --===============8191365088331176304==--
