new NVIDIA license service DLS 3.1 available
Migration Information
Current (legacy) NVIDA license service reaches end of support on July 31st, 2023. Therefore a new NVIDIA license service was prepared. The new NVIDIA license service is based on DLS version 3.1 (Delegated License Service 3.1 - https://docs.nvidia.com/license-system/dls/3.1.0/index.html).
The new NVIDA license service uses the same DNS names and IPs, but different port (443) and requires new client configuration with a token file.
All existing Windows GPU instances require new client configuration or reinstallation. All public Windows GPU images from public Image Management Service already uses the new NVIDIA license service.
Linux GPU instances created from our public images are not effected, as unlicensed NVIDIA open source driver is used.
DNS change in eu-nl to new IPs and new license server is scheduled for 4. March 2024. Old license server is only reachable via old IPs afterwards
Run down of all old license servers is scheduled for 11. March 2024.

How to check connection to new NVIDIA license servers
start PowerShell and run commands:
Test-NetConnection gpulicence01.eu-de.otc-service.com -port 443
Test-NetConnection gpulicence02.eu-de.otc-service.com -port 443
Test-NetConnection 198.19.34.77 -port 443
Test-NetConnection 198.19.44.221 -port 443
test result should be:
TcpTestSucceeded : True
example:
PS C:\Users\Administrator\Desktop> Test-NetConnection gpulicence01.eu-de.otc-service.com -port 443

How to reconfigure NVIDIA license server client on Windows Servers
Reconfiguration with Chocolatey (eu-de only)
- Install Chocolatey client if not already done
# define chocolatey server
$ChocoServer = 'chocolatey.eu-de.otc-service.com'
# download and install the client
Set-ExecutionPolicy Bypass -Scope Process -Force
iex ((New-Object System.Net.WebClient).DownloadString("http://$ChocoServer/install.ps1"))
- Install Chocolatey Package OTCnvidialicense (set ChocoServer with server of region and choose install, upgrade or upgrade all command)
# define chocolatey server
$ChocoServer = 'chocolatey.eu-de.otc-service.com'
# install chocolatey package
choco install OTCnvidialicense --source="http://$ChocoServer/chocolatey"
# force reinstallation chocolatey package and confirm all messages automatically
choco install OTCnvidialicense -y --force --source="http://$ChocoServer/chocolatey"
# upgrade specific chocolatey package (if already installed)
choco upgrade OTCnvidialicense -y --source="http://$ChocoServer/chocolatey"
# upgrade all chocolatey packages
choco upgrade all -y --source="http://$ChocoServer/chocolatey"
Manual Reconfiguration
-
Download NVIDIA client token file (eu-de): eu-de_client_configuration_token.tok
-
Download NVIDIA client token file (eu-nl): eu-nl_client_configuration_token.tok
-
Copy eu-de_client_configuration_token.tok to clients in folder:
C:\Program Files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken
-
verify if the license file location is configured in registry:
if (-not(get-Item -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\GridLicensing' -ErrorAction SilentlyContinue)) { New-Item -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\GridLicensing' -Force -ErrorAction SilentlyContinue } New-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\GridLicensing' -name 'ClientConfigTokenPath' -value 'C:\Program Files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken' -Force -ErrorAction SilentlyContinue Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\GridLicensing' -name 'ClientConfigTokenPath' -value 'C:\Program Files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken' -Force -ErrorAction SilentlyContinue
-
set the correct feature type in registry:
# NVIDIA RTX Virtual Workstation (graphic mode)
$FeatureType = 2
# NVIDIA Virtual Compute Server (compute mode e.g. for p3 (A100) flavvor)
# $FeatureType = 4
# values for older driver versions <= 474.xx (Windows Server 2012R2 and 2016)
New-ItemProperty -Path 'HKLM:\Software\NVIDIA Corporation\Global\GridLicensing' -name 'FeatureType' -value $FeatureType -Force -PropertyType DWORD -ErrorAction SilentlyContinue
Set-ItemProperty -Path 'HKLM:\Software\NVIDIA Corporation\Global\GridLicensing' -name 'FeatureType' -value $FeatureType -Force -ErrorAction SilentlyContinue
# value for newer driver version > 474.xx (Windows Server 2019 and 2022)
New-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\GridLicensing' -name 'FeatureType' -value $FeatureType -Force -PropertyType DWORD -ErrorAction SilentlyContinue
Set-ItemProperty -Path 'HKLM:\SYSTEM\CurrentControlSet\Services\nvlddmkm\Global\GridLicensing' -name 'FeatureType' -value $FeatureType -Force -ErrorAction SilentlyContinue
- Restart the "NVIDIA Display Container LS" service
Restart-Service NVDisplay.ContainerLocalSystem
How to check NVIDIA license server client
- after Restart of "NVIDIA Display Container LS" service wait 60 seconds, then run this powershell command:
if (Test-Path 'C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe') {$nvidia_smi = 'C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe'}
if (Test-Path 'C:\windows\system32\nvidia-smi.exe') {$nvidia_smi = 'C:\windows\system32\nvidia-smi.exe'}
if ($nvidia_smi) {
& $nvidia_smi -a | Select-String 'License Status' | out-string;
} else {
Write-Output 'nvidia-smi.exe not found'
}
- verifiy if a license expiry date is shown
