Configuring a Hyper-V* Virtual Machine for Hardware-Based Hotspots Analysis

This recipe helps you set up a Virtual Machine instance in the Hyper-V environment for hardware performance profiling with Intel® VTune™ Amplifier.


This section lists the hardware and software tools used for the performance analysis scenario.

  • Tools:

  • CPU: Intel® Xeon® processor that supports Intel® Virtualization Technology (Intel® VT)

  • Operating system: Microsoft* Windows* 10 RS5 (October 2018 Update, build 17763.1)

  • BIOS with Intel VT support

Configure a Hyper-V Host

  1. Enable the Intel VT in the BIOS setup on your server:

    1. Access the system BIOS by pressing F2 during the system power-on self test (POST).
    2. Click Advanced > Processor Configuration.
    3. Select Intel® Virtualization Technology and change to Enabled.

    4. Do an AC power cycle for changes to take effect.

  2. Go to Control Panel > Programs > Programs and Features and click Turn Windows features on or off on the left pane.

    The Windows Features dialog box opens.

  3. Expand the Hyper-V feature and select all the check boxes:

  4. Click OK and proceed with the installation.

    When the installation is complete, click Restart now.

Create and Configure a Virtual Machine

On your Hyper-V host (further, host), run Hyper-V Manager from the Start menu to create and configure a new VM (further, VM):

  1. From the Actions panel, click New and select Virtual Machine... :

  2. In the New Virtual Machine Wizard, specify all necessary parameters for the new machine (CPU configuration, Memory, Network, Hard Disk, and others).

    Recommended system requirements for the VTune Amplifier are 4 GB RAM and at least 10 GB free disk space.

  3. Configure your installation source. For example, you can use local installation .iso image:

  4. Start the newly created VM and proceed with the OS installation process.

Configure the Virtual Machine for the Hardware Analysis

For the Windows 10 RS5 based host, prepare a target system instance for profiling by exposing PMU/PEBS/LBR to the VM:

  1. Turn off the newly created VM and launch your host Windows PowerShell from the Start menu.

  2. In the PowerShell, configure your VM to expose PMU, PEBS, LBR to the VM as follows:

    Set-VMProcessor -VMName your_vm_name -Perfmon pmu,pebs,lbr 

  3. Turn on your VM.

Run Hotspots Analysis

Run the VTune Amplifier directly from the VM:

  1. Install the VTune Amplifier on the VM.

  2. Run the VTune Amplifier from Start menu.

  3. Create a project.

    The Configure Analysis window opens.

  4. On the WHERE pane, select Local Host.

  5. On the WHAT pane, specify the location of your application and its working directory.

  6. On the HOW pane, select the Hardware Event-Based Sampling collection mode for the Hotspots analysis.

    If you succeed with exposing PMU/PEBS/LBR, your analysis configuration pane will show no error messages and you will be able to perform the analysis.

  7. Click Start to run the analysis.

    The analysis result opens in the default Hotspots by CPU Utilization viewpoint.


You may perform the Hotspots analysis in multiple VMs running simultaneously.
