Intel® VTune™ Amplifier
If you are a system developer and interested in the performance analysis of a guest Linux* system including KVM modules, consider using this usage mode:
When you run the analysis, the VTune Amplifier collects the data on both host and guest OS and displays merged statistics in the result. Guest OS modules have the [guest] postfix in the grid. For example:
Focus on the Platform tab to analyze your code performance on the guest OS and correlate this data with CPU, GPU, power, hardware event metrics and interrupt count at each moment of time. If you enabled the kvm Ftrace event collection for your target, you can also monitor the statistics for KVM kernel module:
In this mode, the VTune Amplifier collects data only on the kernel space modules on the KVM guest OS. Data on user space modules shows up in the [Unknown] node and includes only high-level statistics.
Call stack data is not collected for this type of profiling.
