Hi,
Does anybody know how virt-manager is getting the CPU usage of the
guests? I need to know how to get the CPU usage of the guests and this
is the only way I can think of. In other words, how does virt-manager
produce the graph of the CPU usage of EACH guest in KVM? I don't
actually need the graph, I just need to get the percentage(%) since I'm
trying to create a Java program to get the CPU usage of each guest in KVM.
This is exactly the question which keeps popping up over and over again.
So I've written a small demo program which does exactly what you need:

Have fun with it!
