This tool is very like xenoprof(if i remember correctly), and traces kvm

smartly. currently, it supports vmexit/mmio/ioport events.
Usage:
- to trace kvm events:
# ./perf kvm-events record
- show the result
# ./perf kvm-events report

Have you thought about dumping a time history -- something similar to
what perf-script can do with dumping events but adding in kvm-specific
analysis like what you are doing in these examples?
I will look into it and put it to my todo list if
