DLS licensing issue

Hello. After installing the DLS according to this video Creating a License Service for NVIDIA AI Enterprise or Virtual GPU - YouTube, the virtual machine cannot get a license. In Powershell it only says:
NLS initialized
Can you help with it?

Hi,

this could have multiple reasons and without getting much more details on the configuration and vGPU setup it is almost impossible to help. Are you eligable for NVES? If yes, why not simply open a support ticket? If no, do you have a partner that may assist you in troubleshooting?

Best regards
Simon

No, I’m not eligible for NVES, and I don’t have a partner either. That’s why I’m asking this question here. Ready to provide the configuration and everything you need

Good starting point would be:
-Hypervisor/version
-hardware model/OEM
-OS in VDI/version
-vGPU version
-vGPU profile
-time in sync? (DLS and VDI?)
-logfile from DLS

-Hypervisor/version
Microsoft Hyper-V Server 2019

-hardware model/OEM
Dell PowerEdge r740xd, Tesla V100 16 GB

-OS in VDI/version
Windows Server 2019 (remote desktops)

-vGPU version
15.1

-vGPU profile
Now is just Virtual Apps. But was RTX Virtual Workstation

-time in sync? (DLS and VDI?)
No, because I don’t know how to sync time in DLS

-logfile from DLS
Sorry, but I don’t know how to do it. I just can to login in DLS via Hypervisor console with login dls_diagnostics and password. But what to do further I don’t know. Can you you say how to do it?

When I pasted token and start NVidia Conteiner LS then this command gave a result:
NLS initialized
NLS initialized

and nothing else

Hi,

is the client token at the right path?
Looks like there is no license information present.

sschaber, Hello.
I have the same problem with the DLS licensing server. In my opinion, I roll the errors described by a colleague above, they get compliance in the log " (Info: NVIDIA Virtual Application - Error: The allowed time to process response has expired) The client key was installed correctly as in the video as indicated above by a colleague.
On questions of introductory data:
-Hypervisor/version
vsphere7 + vCenter 7
Dell PowerEdge r 750, A10 24 Gb
OS Windows Server 2022
vGPU version 15.2
vGPU profile
I conduct tests on 12a
-time in sync? (DLS and VDI?)
No, because I don’t know how to sync time in DLS
-logfile from DLS

The licensing server deployed an OVA file (nls-3.0.0-bios.ova) on vCenter 7

Pretty much a time out of sync issue. Please check the time of the DLS and the time on the VDI. It must be in sync otherwise the token cannot be processed properly.

https://docs.nvidia.com/license-system/latest/nvidia-license-system-user-guide/index.html#dls-ntp-configuration

check the current time with date command as example on the DLS appliance

Indeed, the time on DLS does not coincide with VDI. Can I somehow change the time in the DLC? the created user does not have the right to this action.

Just use the NTP configuration. With proper NTP the time shouldn’t be an issue.

Good afternoon!
Thank you very much. After the NTP change, both on the Licensing Server and on the vm, All licenses became available! I’m surprised that this was the reason.
Good luck with your work!


Hello.

Thank you very much for your response. You gave me the same article that I dealt with today. I created a FeatureType and set the FeatureType registry value to 2 - and the license came. But it says that this license ends in 1 day. Tell me, please, will another license come automatically the next day?

This is not the license that will expire but the lease :)
That’s the default behavior. And yes, for sure you will a new lease the next day.

Thank you very much, it’s very good, you do great things

Hello. Can you help one more time? Please tell me why the license was first updated, but then an error appeared? And when I restarted the Display Container, the license returned

It seems that licenses began to come and return normally. Our network administrators simply turned on internet access at night. Thank you
