New Features in this Release

1.2. Supported Platforms

1.2.1. Supported Hypervisors

For deployment in a virtual machine, the Delegated License Server (DLS) component of the NVIDIA License System is supplied as a virtual appliance. The virtual appliance must be installed on a supported hypervisor software release.

The following hypervisor software releases are supported:

  • Citrix Hypervisor 8.2
  • Linux Kernel-based Virtual Machine (KVM) hypervisors with one of the following QEMU releases:
    • QEMU 4.2.0
    • QEMU 2.12.0 (qemu-kvm-2.12.0-64.el8.2.27782638)
  • Microsoft Windows Server with Hyper-V 2019 Datacenter edition
  • Red Hat Enterprise Linux Kernel-based Virtual Machine (KVM) 9.2, 9.1, 9.0, and 8.8
  • Red Hat Virtualization 4.3
  • Ubuntu Hypervisor 22.04
  • VMware vSphere Hypervisor (ESXi) 8.0.1, 8.0, 7.0.3, 7.0.2, and 7.0.1

1.2.2. Supported Container Orchestration Platforms

For deployment on a supported container orchestration platform, the Delegated License Server (DLS) component of the NVIDIA License System is supplied as a containerized software image.

The following container orchestration platform releases are supported:

  • Docker 20.10.17 with Docker Compose 2.6.0
  • Kubernetes 1.23.8
  • Red Hat OpenShift Container Platform 4.10.67 with Kubernetes 1.23.17

  • VMware Tanzu Application Platform 1.1 with Kubernetes 1.23.6

1.2.3. Supported Operating Systems

For installation on a supported operating system, the Delegated License Server (DLS) component of the NVIDIA License System is supplied as an installable package. The package includes the containerization software and container images that are required to run the NVIDIA Licensing application on the operating system. The operating system can be running in a virtualized server environment on your choice of hypervisor or on a bare-metal server.

Any Red Hat Enterprise Linux 8 or 9 release that is supported by Red Hat is supported.

1.2.4. Licensed Client Support

NVIDIA License System supports specific releases of several NVIDIA software products as licensed clients.

Software Product Supported Releases
NVIDIA® vGPU™ software graphics drivers NVIDIA vGPU software starting with release 13.0

1.2.5. Web Browser Requirements

NVIDIA License System and NVIDIA Licensing Portal were tested with Google Chrome version 86.0.4240.111 (Official Build) (64-bit).

A container orchestration platform cannot control or restrict access to the OS on which the platform is running. Therefore, containerized DLS software images cannot support the features of VM-based DLS virtual appliances that rely on the ability of the appliance to control the underlying OS.

Containerized DLS software images do not support the following features, for which equivalent functionality is available through standard OS interfaces:

  • Log archive settings
  • NTP configuration
  • Static IP address configuration
  • DLS diagnostics user configuration
  • Disk expansion

Because a container orchestration platform cannot control the underlying OS, the following limitations also apply to containerized DLS software images:

  • Online migration from a VM-based DLS virtual appliance to a containerized DLS software image is not supported because the destination containerized DLS software image retains its IP address even after data migration.

    Instead, you must use offline migration when migrating from a VM-based DLS virtual appliance to a containerized DLS software image.

  • When the secondary node is removed from an HA cluster, the containerized DLS software image that hosts the node is not shut down.

    Instead, you must shut down the DLS software container manually.

To address vulnerabilities that were discovered through security scans of the DLS, new releases of third-party software components are included in the delegated license service (DLS) component of NVIDIA License System.

5.2. VM is renewing license from a fresh DLS

Description

For HA based Portal Assisted Upgrade, clients could see some transient failures when the nodes are being set up after Acknowledging Upgrade on the upgraded node.

Status

Open

5.4. Windows clients fail to return leases to the upgraded DLS node

Description

Windows clients cannot return leases to the upgraded DLS node. The failure happens only if the first operation performed by a Windows client is returning leases to an upgraded DLS node. Currently, the DLS upgrade operation does not maintain the auth tokens issued by the existing DLS node. As a result, when the client provides the auth token that was issued before the DLS upgrade, the upgraded node does not acknowledge that token and issues the following error message:

Copy
Copied!
            

Failed to return license to dhcp-10-24-129-182.nvidia.com (Error: invalid token: Signature verification failed.)


After a reboot of the Windows client, the lease that was not returned previously will be assigned to the client. This lease will be returned to the server if the client initiates a lease return after at least one successful lease renewal.

If the virtual machine is shut down, you can manually release the lease by choosing the Force Release option using the License Server GUI or wait until the license expires.

Status

Open

To comply with the terms of the GPL/LGPL v3 license under which the GPL/LGPL v3 licensed Open Source Software (OSS) libraries within the DLS virtual appliance are released, the rsu_admin user has the elevated privileges required to update and upgrade these libraries.

CAUTION:

Any changes to the Ubuntu GPL/LGPL v3 licensed OSS libraries within the DLS virtual appliance might impair the performance of the DLS virtual appliance or prevent it from functioning as required. If you make any changes to these libraries, the affected DLS instance is no longer eligible for support from NVIDIA. It is your responsibility to ensure that the DLS instance continues to perform and function as required.


Ensure that the sudo DLS user account rsu_admin has been created.

  1. Log in as the rsu_admin user to the VM that hosts the DLS virtual appliance.
  2. Determine whether your existing network configuration allows the DLS virtual appliance to reach the Ubuntu package repositories. For example, download information from all configured sources about the latest versions of the packages.
    Copy
    Copied!
                

    $ sudo apt update

  3. If the DLS virtual appliance cannot reach the Ubuntu package repositories, modify your network configuration to allow access to these repositories.
    1. Ensure that your DNS server has the entries required to resolve the domain names of the Ubuntu package repositories.
    2. Delete the symbolic link /etc/resolv.conf.
      Copy
      Copied!
                  

      $ sudo rm -f /etc/resolv.conf

    3. Copy the default resolv.conf file at /run/NetworkManager to /etc/resolv.conf.
      Copy
      Copied!
                  

      $ sudo cp /run/NetworkManager/no-stub-resolv.conf /etc/resolv.conf

  4. Use the Advanced Packaging Tool (APT) of the Ubuntu OS to check for and install any available updates to the Ubuntu GPL/LGPL v3 licensed OSS libraries.
  5. After installing the updates, restore your original network configuration.
    1. Delete the /etc/resolv.conf file that you copied earlier.
      Copy
      Copied!
                  

      $ sudo rm -f /etc/resolv.conf

    2. Re-create the symbolic link /etc/resolv.conf.
      Copy
      Copied!
                  

      $ sudo ln -s /run/NetworkManager/no-stub-resolv.conf /etc/resolv.conf

The file /var/dls/sudouser is created to indicate that the Ubuntu GPL/LGPL v3 licensed OSS libraries within the DLS virtual appliance have been updated or upgraded. If the DLS virtual appliance is hosting a node in an HA cluster, this file is automatically copied to the other node in the cluster.
