Is that exposed to users of libvirt or Qemu in any way?

Thank you very much for helping, but I found out what to do. There is a function called cpu_throttle_set() that does exactly what I needed. 

Happy Holidays.

I think you have to provide much more details:
Qemu version
Host CPU and OS 
Guest CPU and OS 
Application details

There is a program that I run inside of QEMU that doesn't use the virtual CPU very efficiently. It causes QEMU to use 100% of the guest's CPU time. I was wondering if there were a way to reduce the amount of host CPU time that a guest CPU can use? This feature would help prevent laptops from heating up when running QEMU.
