  • Configure NVIDIA License Server On-Prem and Integrate with MCS Provisioned Persistent Catalog


    Uddave Jajoo by Uddave Jajoo, CTA & Indianapolis CUGC Leader

    In 2021, I was asked to migrate the vGPU enabled VMs from one platform to another as our customer was migrating from VMWare Horizon to Citrix XenDesktops. I did not have enough knowledge about NVIDIA and how the GPU processing work in highly intensive graphics processing applications.

    I took help from community members and support teams (both Citrix and NVIDIA) and deployed the solution to provision NVIDIA vGPU-enabled Citrix VDIs on vSphere. This blog post was created 2 years ago but was not published that time. However, I am happy to publish it now to the community so that others could also benefit from it.

    (See also: Configuring NVIDIA vGPU VMs in Azure with Citrix DaaS.)

    Below are the overall configuration steps covering deployment of all the major infrastructure and other components.

    1. NVIDIA vGPU License Server Deployment
    2. Pre-Requisites Open JDK installation
    3. NVIDIA License Server Installation
    4. Access License Server management Interface
    5. Creating license server on NVIDIA portal
    6. Creating VDI Master Image (NVIDIA Driver Installation and vGPU profile)
    7. VDA installation and Machine Catalog creation
    8. Configuring Virtual Machine to enable vGPU profiles

    NVIDIA vGPU License Server Deployment: Open JDK JRE Prerequisite

    1. Install OpenJDK JRE on the server as prerequisite component before installing vGPU License server component
    2. Download java-1.8.0-openjdk-
    1. Run the MSI installer and proceed with the installation wizard
    2. Click Next
    3. Click Next and Install
    4. Monitor the installation and click Finish
    1. Configure system environment variable on the server pointing to jdk location.
      • Edit the System Environment Variables.
      • Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
      • The following is a typical value for the PATH variable: C:\WINDOWS\system32;C:\WINDOWS;"C:\Program Files\Java\jdk-11\bin"
    1. Set JAVA_HOME: 
      • Under System Variables, click New. 
      • Enter the variable name as JAVA_HOME
      • Enter the variable value as the installation path of the JDK (without the bin sub-folder). 
      • Click OK. 
    1. Configure the PATH environment to enable to run JAVA from a command prompt
      • Select the System variables “Path”
      • Click Edit
      • Click on New
      • Type “%JAVA_HOME%\bin” 
      • Click OK.
      • And OK again to apply changes.
    1. Verification:  
      • Change to the Java directory 
      • Type java.exe -version 

    NVIDIA Legacy License Server Installation

    Legacy License server is set to EOL by July 2023, hence NVIDIA offers two different methods for provisioning license server. (DLS) On Premise and Cloud(CLS). In this blog, I am going to cover how to setup a CLS based license server. Steps are very simple and described properly in the NVIDIA documentation as well.


    License System User Guide - NVIDIA Docs – Converting Legacy NVIDIA vGPU Software License Servers to NLS License Servers

    1. Right click the setup file and select run as administrator to proceed with configuration of license server
    1. Open administrative command prompt and navigate to the setup folder and launch setup.exe
    2. When prompted select allow the file to launch, select Allow this file and click OK.
    3. Wait for the setup file to launch and navigate through the wizard.
    4. Click Next in the Introduction Tab
    5. Click Next for EULA
    6. Click Next for Accepting the Apache License
    1. Select the location as default and proceed further with installation, click Next.
    2. In the Choose Firewall Options dialog box, select the ports to be opened in the firewall.
    3. To enable remote clients to access licenses from the server and prevent remote access to the management interface, use the default setting, which sets ports as follows:
      • ‣ Port 7070 is open to enable remote clients to access licenses from the server.
      • ‣ Port 8080 is closed to ensure that the management interface is available only through a web browser running locally on the license server host.
    4. Click Install and proceed further with the installation process.
    1. Wait for the License Server installation script to execute
    2. Click Done once installation is complete.

    Access License Server Management Interface

    1. In a web browser, visit the home page for license server management interface HTTP: http://localhost:8080/licserver
    2. If administrative security is enabled for the license server, log in to the license server.
      • In the license server management interface, select Login.
      • In the Login page that is displayed, enter your user name and password for logging in to the license server and click Authorize.

    The default credentials for the license server administrator account are as follows:

    ‣ admin


    1. Record the license server’s MAC address, by launching the license server management console and navigating to configuration

      MAC Address – 00-XX-XX-XX-XX-XX-00 Note to change the MAC address binding on vecneter level

    2. Add Environment variable on the license server as below, this is needed to ensure the nvidialsadmin utility commands run perfectly fine.

      Variable Name:- FLEXNETLS_BASEURL

      Variable Value:- http://localhost:7070/api/1.0/instances/~

    3. Reboot the server
    4. Enable Administrative security for license server

      Perform this task in a command shell on the license server host.

      Set the property security.enabled to true.

      nvidialsadmin -config -set security.enabled=true Updated the property:security.enabled with value:true successfully

    1. Authenticating with license server

      To provide your password in the command, specify the credentials as follows:


      nvidialsadmin -authorize username password


      In any subsequent nvidialsadmin command, users must provide the required credentials for authenticating with the license server

    2. Run status check on the license server

      nvidialsadmin -authorize admin Admin@123 -status


    Creating a License server on the NVIDIA Portal

    1. Login to NVIDIA Dashboard link to register the license server on portal


    2. Login with the Organization user credentials and create License Server
    1. On the NVIDIA Licensing Portal dashboard, click CREATE LICENSE SERVER.
    2. If you are adding a license server to an organization or virtual group for which a license server has already been created, click CREATE SERVER.
    3. Enter the details as below:

      ServerName: TestNVIDIA

      Description: License Server for NVIDIA vGPU

      MAC Address: 00-XX-XX-XX-XX-XX-00

      Click Add Click create license server

    1. Verify the License server details along with the available license displayed in portal
    1. Download the License File
    1. Login to License server and upload the license file to the server.
    2. Navigate to Licensed Feature Usage

      Verify the details for the License added to the console.
