To maximize the cpu utilization, core 0 is usually shared by service vm and guest vm. But there are no statistics to show the cpu occupation of each vm. This patch is to provide cpu usage statistic for users. To calculate it, a new trace event is added and marked in scheduling context switch, accompanying with a new python script to analyze the data from acrntrace output.
