Further investigation indicates that this issue might be limited to systems running host virtualization software, although I am still waiting for upstream to confirm. My most recent comment in the upstream issue is quoted beneath. --- Bisection reveals the following commit as being responsible. af285d1 Fixes in accounting of guest time when using virtualization The box that I am testing is a Linux KVM host - not a guest. The option to add guest time to the CPU meter is disabled. [ ] Add guest time in CPU meter percentage If I understand this correctly, this commit is either intended to improve the accuracy of CPU accounting in a guest or pertains to the above mentioned option. Either way, it seems to be responsible for inaccurate readings on the host. This has long been fixed by upstream |
