The suggested patch in my original report is already applied. Instead, I believe this is an issue under KVM where the MSR powertop is using (IA32_APERF, 0xe8) is an unimplemented MSR.
http://www.spinics.net/lists/kvm/msg120054.html Ideally powertop would detect it's running under KVM and avoid using unimplemented MSRs. For example if could skip sampling the IA32_APERF MSR and use only TSC records. Alternatively, powertop could have a more robust get_msr() method which handled failure with fallback behavior (and warn of reduced accuracy due to unavailable MSRs). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1541837 Title: powertop crashes inside intel kvm machine To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/powertop/+bug/1541837/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
