I have another problem. As in java bindings there is no way to obtain cpu stats I decided to use a python script. It gives me, for the guest domain, cpu time, system time and user time. Now, what does it mean cpu time? I though that it could be the overall cpu time given to this vm...but the sum doesn't add up: user_time+system_time != cpu_time. As I would need to get a %cpu usage, like virt-manager does (so it IS possible, and it IS in python), what operation do I need to do to make this happen?
Have a look at the implementation of the _sample_cpu_stats method of the vmmDomain class here: https://git.fedorahosted.org/cgit/virt-manager.git/tree/virtManager/domain.p...
