Intel® VTune™ Amplifier 201
Configure the Intel® VTune™ Amplifier to analyze performance on a KVM guest system.
Unlike other virtual machine systems, systems using KVM on a Linux* host to access a Linux guest can have VTune Amplifier installed on either the host system to analyze performance on the guest system or installed directly on the guest system to analyze the guest system. Additional information about installing VTune Amplifier is available from the Linux installation guides.
If you are installing VTune Amplifier on a guest system with KVM modules, use the following steps to enable event-based sampling analysis:
From the host system, open the configuration settings for the virtual machine.
Select the CPUs or Processor option on the left.
Enter host-passthrough into the Model field to pass through the host CPU features without modifying the guest system.
Click Apply to save the changes.
This section applies to systems with KVM modules configured to run VTune Amplifier on the host system to analyze a guest system.
After installation on the host Linux system succeeds, select local host as the target system on the Analysis Target tab and use the Analyze KVM Guest OS option from the Advanced section to run the analysis on the KVM system. For more information, see KVM Guest OS Profiling.
