2.1.1. Switching the Mode of a GPU that Supports Multiple Display Modes

Some GPUs support displayless and display-enabled modes but must be used in NVIDIA vGPU software deployments in displayless mode.

The GPUs listed in the following table support multiple display modes. As shown in the table, some GPUs are supplied from the factory in displayless mode, but other GPUs are supplied in a display-enabled mode.

GPU Mode as Supplied from the Factory
NVIDIA A40 Displayless
NVIDIA RTX A5000 Display enabled
NVIDIA RTX A6000 Display enabled

A GPU that is supplied from the factory in displayless mode, such as the NVIDIA A40 GPU, might be in a display-enabled mode if its mode has previously been changed.

To change the mode of a GPU that supports multiple display modes, use the displaymodeselector tool, which you can request from the NVIDIA Display Mode Selector Tool page on the NVIDIA Developer website.

Note:

Only the following GPUs support the displaymodeselector tool:

  • NVIDIA A40
  • NVIDIA RTX A5000
  • NVIDIA RTX A6000

Other GPUs that support NVIDIA vGPU software do not support the displaymodeselector tool and, unless otherwise stated, do not require display mode switching.

2.1.2. Switching the Mode of a Tesla M60 or M6 GPU

Tesla M60 and M6 GPUs support compute mode and graphics mode. NVIDIA vGPU requires GPUs that support both modes to operate in graphics mode.

Recent Tesla M60 GPUs and M6 GPUs are supplied in graphics mode. However, your GPU might be in compute mode if it is an older Tesla M60 GPU or M6 GPU or if its mode has previously been changed.

To configure the mode of Tesla M60 and M6 GPUs, use the gpumodeswitch tool provided with NVIDIA vGPU software releases. If you are unsure which mode your GPU is in, use the gpumodeswitch tool to find out the mode.

Note:

Only Tesla M60 and M6 GPUs support the gpumodeswitch tool. Other GPUs that support NVIDIA vGPU do not support the gpumodeswitch tool and, except as stated in Switching the Mode of a GPU that Supports Multiple Display Modes, do not require mode switching.

Even in compute mode, Tesla M60 and M6 GPUs do not support NVIDIA Virtual Compute Server vGPU types.

For more information, refer to gpumodeswitch User Guide.

3.7. NLS client fails to acquire a license with the error The allowed time to process response has expired

Description

A licensed client of NVIDIA License System (NLS) fails to acquire a license with the error The allowed time to process response has expired. This error can affect clients of a Cloud License Service (CLS) instance or a Delegated License Service (DLS) instance.

This error occurs when the time difference between the system clocks on the client and the server that hosts the CLS or DLS instance is greater than 10 minutes. A common cause of this error is the failure of either the client or the server to adjust its system clock when daylight savings time begins or ends. The failure to acquire a license is expected to prevent clock windback from causing licensing errors.

Workaround

Ensure that system clock time of the client and any server that hosts a DLS instance match the current time in the time zone where they are located. To prevent this error from occurring when daylight savings time begins or ends, enable the option to automatically adjust the system clock for daylight savings time:

  • Windows: Set the Adjust for daylight saving time automatically option.
  • Linux: Use the hwclock command.

Status

Not a bug

3.8. With multiple active sessions, NVIDIA Control Panel incorrectly shows that the system is unlicensed

Description

In an environment with multiple active desktop sessions, the Manage License page of NVIDIA Control Panel shows that a licensed system is unlicensed. However, the nvidia-smi command and the management interface of the NVIDIA vGPU software license server correctly show that the system is licensed. When an active session is disconnected and reconnected, the NVIDIA Display Container service crashes.

The Manage License page incorrectly shows that the system is unlicensed because of stale data in NVIDIA Control Panel in an environment with multiple sessions. The data is stale because NVIDIA Control Panel fails to get and update the settings for remote sessions when multiple sessions or no sessions are active in the VM. The NVIDIA Display Container service crashes when a session is reconnected because the session is not active at the moment of reconnection.

3.12. Windows 2012 R2 licensed clients cannot acquire licenses from a DLS instance

Description

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.

Workaround

Use the legacy NVIDIA vGPU software license server instead of NVIDIA License System (NLS).

3.13. 13.0 Only: Windows 2012 R2 licensed clients cannot acquire licenses from a CLS or DLS instance

Description

NVIDIA vGPU software licensed clients running in a Windows 2012 R2 VM cannot acquire licenses from a Cloud License Service (CLS) instance or a Delegated License Service (DLS) instance. During the license acquisition process, the vGPU licensing service compares the size of the message to be sent to the CLS or DLS instance before and after encryption. On Windows 2012 R2, the MSDN API for encrypting the message outputs a shorter encrypted message than the plain text message. As a result, the validation check in the service fails, which causes the client to fail to acquire a license.

Status

Resolved in NVIDIA vGPU software 13.1

3.14. A licensed client might fail to acquire a license if a proxy is set

Description

If a proxy is set with a system environment variable such as HTTP_PROXY or HTTPS_PROXY, a licensed client might fail to acquire a license.

Workaround

Perform this workaround on each affected licensed client.

  1. Add the address of the NVIDIA vGPU software license server to the system environment variable NO_PROXY.

    The address must be specified exactly as it is specified in the client's license server settings either as a fully-qualified domain name or an IP address. If the NO_PROXY environment variable contains multiple entries, separate the entries with a comma (,).

    If high availability is configured for the license server, add the addresses of the primary license server and the secondary license server to the system environment variable NO_PROXY.

  2. Restart the NVIDIA driver service that runs the core NVIDIA vGPU software logic.

    • On Windows, restart the NVIDIA Display Container service.
    • On Linux, restart the nvidia-gridd service.

Description

On Linux, the frame rate might drop to 1 frame per second (FPS) after NVIDIA vGPU software has been running for several minutes. Only some applications are affected, for example, glxgears. Other applications, such as Unigine Heaven, are not affected. This behavior occurs because Display Power Management Signaling (DPMS) for the Xorg server is enabled by default and the display is detected to be inactive even when the application is running. When DPMS is enabled, it enables power saving behavior of the display after several minutes of inactivity by setting the frame rate to 1 FPS.

Workaround

  1. If necessary, stop the Xorg server.

    Copy
    Copied!
                

    # /etc/init.d/xorg stop

  2. In a plain text editor, edit the /etc/X11/xorg.conf file to set the options to disable DPMS and disable the screen saver.

    1. In the Monitor section, set the DPMS option to false.
      Copy
      Copied!
                  

      Option "DPMS" "false"

    2. At the end of the file, add a ServerFlags section that contains option to disable the screen saver.
      Copy
      Copied!
                  

      Section "ServerFlags" Option "BlankTime" "0" EndSection

    3. Save your changes to /etc/X11/xorg.conf file and quit the editor.
  3. Start the Xorg server.

3.19. Microsoft DDA fails with some GPUs

Description

Microsoft Discrete Device Assignment (DDA) fails with GPUs that have more than 16 GB of GPU memory. After the NVIDIA vGPU software graphics driver is installed in the guest VM, a second display device appears on the GPU and the driver prompts for a reboot. After the reboot, the device disappears and the Microsoft Hyper-V Video device appears.

This issue occurs because less memory-mapped input/output (MMIO) space is configured for the operating system than the device requires.

Workaround

Perform this workaround in a Windows Power Shell window on the hypervisor host.

Set the upper MMIO space to the amount that the device requires to allow all of the MMIO to be mapped. Upper MMIO space starts at approximately 64 GB in address space.

Copy
Copied!
            

Set-VM –HighMemoryMappedIoSpace mmio-space –VMName vm-name

mmio-space
The amount of MMIO space that the device requires, appended with the appropriate unit of measurement, for example, 64GB for 64 GB of MMIO space.

The required amount of MMIO space depends on the amount of BAR1 memory on the installed GPUs and the number of GPUs assigned to the VM as follows:

mmio-space = 2 ˟ gpu-bar1-memory ˟ assigned-gpus

gpu-bar1-memory
The amount of BAR1 memory on one of the installed GPUs. For example, in a server in which eight GPUs are installed and each GPU has 32 GB of BAR1 memory, gpu-bar1-memory is 32 GB.
assigned-gpus
The number of GPUs assigned to the VM.
vm-name
The name of the VM to which the GPU is assigned.

The following example sets the upper MMIO space to 64 GB for the VM named mygpuvm, to which one GPU with 32 GB of BAR1 memory is assigned.

Copy
Copied!
            

Set-VM –HighMemoryMappedIoSpace 64GB –VMName mygpuvm

3.21. NVIDIA vGPU software graphics driver fails after Linux kernel upgrade with DKMS enabled

Description

After the Linux kernel is upgraded (for example by running sudo apt full-upgrade) with Dynamic Kernel Module Support (DKMS) enabled, the nvidia-smi command fails to run. If DKMS is enabled, an upgrade to the Linux kernel triggers a rebuild of the NVIDIA vGPU software graphics driver. The rebuild of the driver fails because the compiler version is incorrect. Any attempt to reinstall the driver fails because the kernel fails to build.

When the failure occurs, the following messages are displayed:

Copy
Copied!
            

-> Installing DKMS kernel module: ERROR: Failed to run `/usr/sbin/dkms build -m nvidia -v 470.63.01 -k 5.3.0-28-generic`: Kernel preparation unnecessary for this kernel. Skipping...

ERROR: Installation has failed. Please see the file '/var/log/nvidia-installer.log' for details. You may find suggestions on fixing installation problems in the README available on the Linux driver download page at www.nvidia.com.


Workaround

When installing the NVIDIA vGPU software graphics driver with DKMS enabled, use one of the following workarounds:

  • Before running the driver installer, install the dkms package, then run the driver installer with the -dkms option.
  • Run the driver installer with the --no-cc-version-check option.

3.23. Frame capture while the interactive logon message is displayed returns blank screen

Description

Because of a known limitation with NvFBC, a frame capture while the interactive logon message is displayed returns a blank screen.

An NvFBC session can capture screen updates that occur after the session is created. Before the logon message appears, there is no screen update after the message is shown and, therefore, a black screen is returned instead. If the NvFBC session is created after this update has occurred, NvFBC cannot get a frame to capture.

Workaround

Press Enter or wait for the screen to update for NvFBC to capture the frame.

3.24. RDS sessions do not use the GPU with some Microsoft Windows Server releases

Description

When some releases of Windows Server are used as a guest OS, Remote Desktop Services (RDS) sessions do not use the GPU. With these releases, the RDS sessions by default use the Microsoft Basic Render Driver instead of the GPU. This default setting enables 2D DirectX applications such as Microsoft Office to use software rendering, which can be more efficient than using the GPU for rendering. However, as a result, 3D applications that use DirectX are prevented from using the GPU.

Version

  • Windows Server 2019
  • Windows Server 2016
  • Windows Server 2012

Solution

Change the local computer policy to use the hardware graphics adapter for all RDS sessions.

  1. Choose Local Computer Policy > Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Remote Session Environment.

  2. Set the Use the hardware default graphics adapter for all Remote Desktop Services sessions option.

3.25. A segmentation fault in DBus code causes nvidia-gridd 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.

To prevent this issue, the GUI for licensing is disabled by default. You might encounter this issue if you have enabled the GUI for licensing and are using Red Hat Enterprise Linux 6.8 or 6.9, or CentOS 6.8 and 6.9.

3.26. 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.

Workaround

This workaround requires sudo privileges.

Note:

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 you are licensing a physical GPU for vCS, you must use the configuration file /etc/nvidia/gridd.conf.

  1. If NVIDIA X Server Settings is running, shut it down.
  2. If the /etc/nvidia/gridd.conf file does not already exist, create it by copying the supplied template file /etc/nvidia/gridd.conf.template.

  3. As root, edit the /etc/nvidia/gridd.conf file to set the EnableUI option to TRUE.

  4. Start the nvidia-gridd service.

    Copy
    Copied!

3.27. 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.
