We want to characterize or understand the behavior of a virtual machine (VM). Is it a CPU-intensive or I/O-intensive VM? We are going to use the following tools such as xentop and pidstat. Let's see which metrics would be appropriate to use to identify the characteristics of VM. VIRTUALIZED ENVIRONMENT Monitoring 1. XenTop When do we have to monitor dom0 and domU ?? source is available under too..
