Greetings sir,
         I am currently taking up Computer Science in my school. I just want to ask how do you get the CPU usage and Memory usage of the VMs (I'm referring sir to the graphs that the Virtual Machine Manager is displaying)? I need to get the numbers (the numbers are enough, I don't need the graph) of these informations because I will be needing it for my thesis. What suggestions can you give me? Like create a program in C or Java or Python using the libvirt API, etc. Your help will be much appreciated sir. Thank you very much.
 P.S. I could explain what my thesis is all about in an email if you want/need sir. Thanks again
