How can I get the CPU usage of the domain? [...]
As Daniel told me two days ago, cpuTime shows the absolute CPU time consumed since boot. To get % CPU time, take two readings 'n' seconds apart and calculate the delta between them.
I guess so, but what is the precision of the returned cpu time. I don't think it's 1/HZ as host machine is according to my experiments. Thanks for your reply.
