[virt-tools-list] How does virt-manager get the CPU usage of a guest/vm

[Restituto Marcus Arevalo]

Hi,

I need to know how the virt-manager is getting the CPU usage of each guest/vm? I mean where does it get the graph it outputs? Does anybody have an idea where I should start researching? I tried understanding the Libvirt API but I think it just outputs cpu time. Any suggestion would be much appreciated. Thanks

Marco
