4.1. 5.1, 5.2 Only: Issues in remote desktop sessions if a license is acquired after a session is started
Description
A VM might acquire a license for NVIDIA vGPU software after a remote desktop session has connected to the VM. In this situation, some licensed features and capabilities are not available to a properly licensed vGPU or pass-through GPU in the session. For example, the updated maximum resolution supported is not available.
Workaround
Before attempting this workaround, confirm that the VM has obtained the correct license for NVIDIA vGPU software.
-
After installing the guest VM driver package and configuring required license settings on the VM (or on the master image used for VM deployment), set the
IgnoreSP
property to 1.-
On Windows, add the following registry setting:
[HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\GridLicensing] "IgnoreSP"=dword:00000001
-

4.4. 5.2 Only: The license expires prematurely in Linux guest VMs
Description
In Linux guest VMs, the license expires before the default borrow period has elapsed. In normal operation, the license is renewed periodically at an interval that depends on the license borrow period. As a result, a failure to renew the license may cause the license to expire before the default borrow period has elapsed.
Workaround
To reduce the possibility of license-renewal failures caused by transient network issues, increase the license borrow period to a value of about 7 days.
Status
Resolved in NVIDIA vGPU software release 5.3.

<a href="#bug-1895945-nvidia-gridd-segfaults-in-dbus-code-on-centos-6-8-6-9" target="_self">nvidia-gridd</a>
to exit on Red Hat Enterprise Linux and CentOS
Description
On Red Hat Enterprise Linux 6.8 and 6.9, and CentOS 6.8 and 6.9, a segmentation fault in DBus code causes the nvidia-gridd service to exit.
The nvidia-gridd service uses DBus for communication with NVIDIA X Server Settings to display licensing information through the Manage License page. Disabling the GUI for licensing resolves this issue.
Since 5.1: The GUI for licensing is disabled by default.
Version
Red Hat Enterprise Linux 6.8 and 6.9
CentOS 6.8 and 6.9
NVIDIA vGPU software 5.0
5.0 Only: Workaround
This workaround requires sudo privileges.

EnableUI
option toFALSE
. -
Start the
nvidia-gridd
service.# sudo service nvidia-gridd start
-
Confirm that the
nvidia-gridd
service has obtained a license by examining the log messages written to /var/log/messages.# sudo grep gridd /var/log/messages … Aug 5 15:40:06 localhost nvidia-gridd: Started (4293) Aug 5 15:40:24 localhost nvidia-gridd: License acquired successfully.

4.10. Since 5.1: No Manage License option available in NVIDIA X Server Settings by default
Description
By default, the Manage License option is not available in NVIDIA X Server Settings. This option is missing because the GUI for licensing on Linux is disabled by default to work around the issue that is described in A segmentation fault in DBus code causes nvidia-gridd to exit on Red Hat Enterprise Linux and CentOS.
Version
NVIDIA vGPU software 5.1
Workaround
This workaround requires sudo privileges.
Do not use this workaround with Red Hat Enterprise Linux 6.8 and 6.9 or CentOS 6.8 and 6.9. To prevent a segmentation fault in DBus code from causing the nvidia-gridd
service from exiting, the GUI for licensing must be disabled with these OS versions.
- If NVIDIA X Server Settings is running, shut it down.
-
If the /etc/nvidia/gridd.conf file does not already exist, create it by copying the supplied template file /etc/nvidia/gridd.conf.template.
-
As root, edit the /etc/nvidia/gridd.conf file to set the
EnableUI
option toTRUE
. -
Start the
nvidia-gridd
service.# sudo service nvidia-gridd start
When NVIDIA X Server Settings is restarted, the Manage License option is now available.

4.11. Since 5.1: The
<a href="#bug-200359469-nvidia-gridd-service-fails-at-default-boot" target="_self">nvidia-gridd</a>
service fails because the required configuration is not provided
Description
The nvidia-gridd
service exits with an error because the required configuration is not provided.
The known issue described in A segmentation fault in DBus code causes nvidia-gridd to exit on Red Hat Enterprise Linux and CentOS causes the NVIDIA X Server Settings page for managing licensing settings through a GUI to be disabled by default. As a result, if the required license configuration is not provided through the configuration file, the service exits with an error.
Details of the error can be obtained by checking the status of the nvidia-gridd
service.

4.13. Licenses remain checked out when VMs are forcibly powered off
Description
NVIDIA vGPU software licenses remain checked out on the license server when non-persistent VMs are forcibly powered off.
The NVIDIA service running in a VM returns checked out licenses when the VM is shut down. In environments where non-persistent licensed VMs are not cleanly shut down, licenses on the license server can become exhausted. For example, this issue can occur in automated test environments where VMs are frequently changing and are not guaranteed to be cleanly shut down. The licenses from such VMs remain checked out against their MAC address for seven days before they time out and become available to other VMs.
Resolution
If VMs are routinely being powered off without clean shutdown in your environment, you can avoid this issue by shortening the license borrow period. To shorten the license borrow period, set the LicenseInterval
configuration setting in your VM image. For details, refer to Virtual GPU Client Licensing User Guide.
