Seem there is no way to get host CPU usage in libvirt API? I can get freeMemory by  virNodeGetFreeMemory, but no cpu usage API.
How about add a new api for it? The host CPU usage is also important for VM creation and migration decision, like the free memory.
Yes, I know, I can got it from "top"...:)
