When it comes to performance monitoring KVM provides sophisticated tools to deep dive into specific aspects. For example, kvm_stat or perf allows analyzing the exits from a guest mode.

Other hypervisors offer a much better out of the box experience.
This talk is about extending the tooling for KVM stats to better integrate into the bigger picture.
