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
Note:
Support for node-locked licensing was introduced in NVIDIA vGPU software 15.0. It is not supported in earlier NVIDIA vGPU software releases. |
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.

5.3. Lease Borrow Failing post Upgrade to DLS 3.3- BadRequestError(Invalid origin ref)
Description
Once the user upgrades to DLS 3.3 and prior to upgrade if the older DLS instance had acquired a lease and post upgrade if the client is restarted - then There is a Failures to acquire a lease due to Error: Invalid origin ref).
This issue affects only licenses checked out from DLS instances while the Offline Lease option is enabled. It does not affect any licenses checked out from CLS instances or licenses checked out from DLS instances after the Offline Lease option is disabled.
WAR - Reboot of the vGPU Client or the NV Display Container LS Service allows the VM to acquire a license post upgrade.
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:
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

5.5. Service instances might be unable to reclaim unused licenses on clients with an invalid or empty MAC address
Description
When a client with an invalid or empty MAC address requests a license, the service instance grants the request and locates the client through the client's IP address. In an environment where the clients are VM instances with reused MAC addresses, the service instance might have granted licenses to multiple clients with invalid or empty MAC addresses. If a client in such an environment is abruptly shut down and cannot return the license, the service instance cannot locate the VM to reclaim the unused license on it. The license remains checked out until it expires, when the service instance can reclaim it.
Workaround
Forcibly release licenses acquired by client VMs with invalid or empty MAC addresses that have greater than usual longevity.

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.
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.
- Log in as the
rsu_admin
user to the VM that hosts the DLS virtual appliance. - Edit the /etc/apt/sources.list .
- Add this repository list:
$ sudo nano /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu/ jammy main universe restricted multiverse deb-src http://archive.ubuntu.com/ubuntu/ jammy main universe restricted multiverse deb http://archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted multiverse deb-src http://archive.ubuntu.com/ubuntu/ jammy-updates main universe restricted multiverse deb http://security.ubuntu.com/ubuntu jammy-security main universe restricted multiverse deb-src http://security.ubuntu.com/ubuntu jammy-security main universe restricted multiverse
- Update the apt list.
$ sudo apt update
- Add this repository list:
- 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.
$ sudo apt update
- If the DLS virtual appliance cannot reach the Ubuntu package repositories, modify your network configuration to allow access to these repositories.
- Ensure that your DNS server has the entries required to resolve the domain names of the Ubuntu package repositories.
- Delete the symbolic link /etc/resolv.conf.
$ sudo rm -f /etc/resolv.conf
- Copy the default
resolv.conf
file at /run/NetworkManager to /etc/resolv.conf.$ sudo cp /run/NetworkManager/no-stub-resolv.conf /etc/resolv.conf
- 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.
- After installing the updates, restore your original network configuration.
- Delete the /etc/resolv.conf file that you copied earlier.
$ sudo rm -f /etc/resolv.conf
- Re-create the symbolic link /etc/resolv.conf.
$ sudo ln -s /run/NetworkManager/no-stub-resolv.conf /etc/resolv.conf
- Delete the /etc/resolv.conf file that you copied earlier.
- Once the package upgrade is complete, remove sources.list created in Step 2.
$ sudo rm /etc/apt/sources.list
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.
