Hypervisor Software Releases

This release supports only the hypervisor software versions listed in the table.

Note: If a specific release, even an update release, is not listed, it’s not supported.
Software Version Supported

Microsoft Windows Server

Windows Server 2016 1709 with Hyper-V role

Windows Server 2016 1607 with Hyper-V role

Guest OS Support

NVIDIA vGPU software supports several Windows releases and Linux distributions as a guest OS using GPU pass-through.

Microsoft Windows Server with Hyper-V role supports GPU pass-through over Microsoft Virtual PCI bus. This bus is supported through paravirtualized drivers.

Note:

Use only a guest OS release that is listed as supported by NVIDIA vGPU software with your virtualization software. To be listed as supported, a guest OS release must be supported not only by NVIDIA vGPU software, but also by your virtualization software. NVIDIA cannot support guest OS releases that your virtualization software does not support.

In pass-through mode, GPUs based on the Pascal architecture support only 64-bit guest operating systems. No 32-bit guest operating systems are supported in pass-through mode for these GPUs.

Windows Guest OS Support

NVIDIA vGPU software supports only the Windows releases listed as a guest OS on Microsoft Windows Server.

Note:

If a specific release, even an update release, is not listed, it’s not supported.

  • Windows Server 2016 1607, 1709
  • Windows Server 2012 R2 with patch Windows8.1-KB3133690-x64.msu

NVIDIA Software Security Updates in Release 6.0

No NVIDIA software security updates are reported in this release for Microsoft Windows Server.

4. Known Issues

Screen resolution reverts to a lower value after a VM is rebooted

Description

When a VM is booted, the NVIDIA vGPU software display driver is initially unlicensed. Screen resolution is limited to a maximum of 1280×1024 until the VM requires a license for NVIDIA vGPU software. Because the higher resolutions are not available, the OS falls back to next available resolution in its mode list (for example, 1366×768) even if the resolution for the VM had previously been set to a higher value (for example, 1920×1080). After the license has been acquired, the OS does not attempt to set the resolution to a higher value.

This behavior is the expected behavior for licensed NVIDIA vGPU software products.

Workaround

Manually set the screen resolution to the required higher value after the VM has acquired the NVIDIA vGPU software license.

Status

Not a bug

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.

  1. After installing the guest VM driver package and configuring required license settings on the VM (or on the master image used for VM deployment), add the following registry setting:

    [HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\GridLicensing] 
    "IgnoreSP"=dword:00000001
  2. Restart the VM.

Multiple display heads are not detected by Ubuntu 14.04 guest VMs

Description

After an Ubuntu 14.04 guest VM has acquired a license, multiple display heads connected to the VM are not detected.

Version

Ubuntu 14.04

Workaround

To see all the connected display heads after the VM has acquired a license, open the Displays settings window and click Detect displays.

On GPUs based on the Pascal architecture, Ubuntu 16.04 VMs run slowly after acquiring a license

Description

On GPUs based on the Pascal architecture, Ubuntu VMs to which an NVIDIA vGPU or pass-through GPU is assigned run slowly after acquiring a license. Ubuntu VMs that have not been assigned an NVIDIA vGPUor pass-through GPU run noticeably faster.

Workaround

After the VM has acquired a license, restart the lightdm service.

Status

Open.

Resolution is not updated after a VM acquires a license and is restarted

Description

In a Red Enterprise Linux 7.3 guest VM, an increase in resolution from 1024×768 to 2560×1600 is not applied after a license is acquired and the gridd service is restarted. This issue occurs if the multimonitor parameter is added to the xorg.conf file.

Version

Red Enterprise Linux 7.3

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.

Version

Red Hat Enterprise Linux 6.8 and 6.9

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.
  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.

    # sudo service nvidia-gridd start

When NVIDIA X Server Settings is restarted, the Manage License option is now available.

Status

Open

The nvidia-gridd 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.

The Apply button is disabled after change to unlicensed mode

Description

After the mode is changed from licensed Quadro Virtual Datacenter Workstation Edition mode to Unlicensed Tesla mode, the Apply button on the Manage GRID License page is disabled. As a result, NVIDIA X Server Settings cannot be used to switch to Tesla (Unlicensed) mode on a licensed system.

Workaround

  1. Start NVIDIA X Server Settings by using the method for launching applications provided by your Linux distribution.
  2. In the NVIDIA X Server Settings window that opens, click Manage GRID License.
  3. Clear the Primary Server field.
  4. Select the Tesla (unlicensed) option.
  5. Click Apply.

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.
