Configuring a Hyper-V* Virtual Machine for Hardware-Based Hotspots Analysis
- CPU: Intel® Xeon® processor that supports Intel® Virtualization Technology (Intel® VT)You can also use any Intel microarchitecture with performance monitoring hardware, such as:
- Operating system:Microsoft* Windows Server 2019 or Windows 10 Version 1809 (October 2018 Update) or later
- BIOSwith Intel VT support
Configure a Hyper-V Host
- Enable the Intel VT in the BIOS setup on your server:
- Access the system BIOS by pressingF2during the system power-on self test (POST).
- ClickAdvanced>Processor Configuration.
- SelectIntel® Virtualization Technologyand change toEnabled.
- Do an AC power cycle for changes to take effect.
- Go toControl Panel>Programs>Programs and Featuresand clickTurn Windows features on or offon the left pane.TheWindows Featuresdialog box opens.
- Expand theHyper-Vfeature and select all the check boxes:
- ClickOKand proceed with the installation.When the installation is complete, clickRestart now.
Create and Configure a Virtual Machine
- From theActionspanel, clickNewand selectVirtual Machine...:
- In theNew Virtual Machine Wizard, specify all necessary parameters for the new machine (CPU configuration, Memory, Network, Hard Disk, and others).Recommended system requirements for theVTuneare 4 GB RAM and at least 10 GB free disk space.Profiler
- Configure your installation source. For example, you can use local installation.isoimage:
- Start the newly created VM and proceed with the OS installation process.
Configure the Virtual Machine for the Hardware Analysis
- Turn off the newly created VM and launch your host Windows PowerShell as an Administrator from theStartmenu.
- 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
- Turn on your VM.
Run Hotspots Analysis
- Install theVTuneon the VM.Profiler
- Run theVTunefromProfilerStartmenu.
- Create a project.TheConfigure Analysiswindow opens.
- On theWHEREpane, selectLocal Host.
- On theWHATpane, specify the location of your application and its working directory.
- On theHOWpane, select theHardware Event-Based Samplingcollection 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.
- ClickStartto run the analysis.The analysis result opens in the defaultHotspots by CPU Utilizationviewpoint.
