1.1.3. Web Browser Requirements

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

1.2. Changes in this Release

DLS instance registration method for classified networks
DLS custom configuration for the desired NTP server
Major enhancements and changes to the UI
Expedited method for creating, binding, and installing a CLS instance
The default CLS Service Instance can be edited
Added support for DLS disk expansion
Bulk force release of licenses to the license server is supported
DLS Appliance version 1.1 now comes with Ubuntu 20.04.3
Miscellaneous bug fixes

Only resolved issues that have been previously noted as known issues or had a noticeable user impact are listed. The summary and description for each resolved issue indicate the effect of the issue on NVIDIA License System before the issue was resolved.

Bug ID	Summary and Description
3381768	On the DLS Appliance, the installed version of `nginx` is prior to 1.17.7, therefore it is affected by an information disclosure vulnerability. As a workaround, you should update `nginx` to version 1.20.
3400123	Windows 2012 R2 licensed clients cannot acquire licenses from a DLS instance NVIDIA vGPU software licensed clients running in a Windows 2012 R2 VM cannot acquire licenses from a Delegated License Service (DLS) instance. This issue occurs because the TLS handshake between the client VM and DLS instance is failing with schannel error code `0x80090326(SEC_E_ILLEGAL_MESSAGE)`, indicating that the client has encountered an unrecoverable error during the TLS handshake.
3368276	The set-static-ip-cli.sh script fails with `Error: unknown connection ''` or `Permission Denied` errors The /etc/adminscripts/set-static-ip-cli.sh does not work because the `dls_system` user does not have the required permissions to execute this script. Any attempt to use the script to set the IP address of a DLS virtual appliance from the hypervisor fails with the error messages `Error: unknown connection ''` or `Permission Denied`.
3368276	DLS virtual appliance Set Up page cannot be accessed through an IP v6 address The DLS virtual appliance Set Up page cannot be accessed through an IP v6 address. If you specify an IP v6 address in the URL for connecting to the DLS virtual appliance, the Login page opens instead of the Set Up page. However, it is not possible to log in to the DLS virtual appliance from this page because the DLS administrator user has not been registered.

3. Known Issues

3.1. Client fails to acquire offline license when rebooted

Description

When a licensed client that is configured with an offline license is rebooted, the client might fail to acquire a license. When this issue occurs, the following message is written to the licensing event log file on the client:

Copy
Copied!

            
            Client fingerprint mismatch - No valid lease found in local trusted store

This issue occurs when the MAC addresses of the network adapters for a client change when the client is rebooted. When the MAC addresses change, the NVIDIA vGPU software graphics driver treats the client as a new client and the offline license in the client's trusted storage database is discarded.

Typically, the MAC addresses change because the network configuration of the client has been explicitly changed by an administrator. However, the MAC address of a client can unexpectedly change when the client is rebooted for several reasons, for example:

The client requests a license before the client's network interfaces are initialized.
Docker or the NVIDIA Container Runtime for Docker is installed on the client and the ifconfig command lists it as a network interface.

A. Creating the DLS sudo User Account

If necessary, you can create a predefined sudo user account for a DLS virtual appliance. This user account has the elevated privileges required to update and upgrade the Ubuntu GPL/LGPL v3 licensed Open Source Software (OSS) libraries within the DLS virtual appliance. This account provides no other access to a DLS virtual appliance.

This account is provided to comply with the terms of the GPL/LGPL v3 license under which some libraries in the Ubuntu operating system in the DLS virtual appliance are released.
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.

Perform this task for each DLS virtual appliance for which you want to create the DLS sudo user account. If the DLS virtual appliance is hosting a node in an HA cluster, the creation of the user is not automatically propagated to the other node in the cluster.

From the hypervisor, log in as the user dls_system to the VM that hosts the DLS virtual appliance. You don't need to provide a password to log in as the dls_system user.

Run the /etc/adminscripts/enable_sudo.sh script.

Copy
Copied!

            
            $ /etc/adminscripts/enable_sudo.sh

When prompted, provide a password for this user.

The sudo user with elevated privileges rsu_admin is created.

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.

In addition, to update the OS or install packages on Ubuntu:

Test to make sure the Ubuntu repositories are reachable with the existing network settings.
If the repository URLs are not getting resolved, you should delete the symlink /etc/resolv.conf, and copy the default resolv.conf located at /run/NetworkManager to /etc/resolv.conf.
Copy

Copied!
```
            
            sudo rm -f /etc/resolv.conf
        
```
Copy

Copied!
```
            
            sudo cp /run/NetworkManager/no-stub-resolv.conf /etc/resolv.conf
        
```
Note:

Note:
Before you copy /run/NetworkManager/resolv.conf, make sure you make a DNS server entry that will resolve the Ubuntu (or any custom) package repositories.

Once the OS update/upgrade is done, please restore the network configurations to their original state by executing the following commands:

Copy
Copied!

            
            sudo rm -f /etc/resolv.conf

Copy
Copied!

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