If you can sink some time into it, there is libxenstat. The python
bindings are a bit broken and it didnt manage to compile it on 64bit.
It gives fine grained results though. I think the HV time is not in
there, but if you're under load you should be able to calculate it
simply by looking at the timers.

I think sedf had a limit in that it only works as intended with one
core. Anyone remember if thats true?
