3. Known Product Limitations

Known product limitations for this release of NVIDIA GRID are described in the following sections.

vGPU profiles with 512 Mbytes or less of frame buffer support only 1 virtual display head on Windows 10

Description

To reduce the possibility of memory exhaustion, vGPU profiles with 512 Mbytes or less of frame buffer support only 1 virtual display head on a Windows 10 guest OS.

The following vGPU profiles have 512 Mbytes or less of frame buffer:

  • Tesla M6-0B, M6-0Q
  • Tesla M10-0B, M10-0Q
  • Tesla M60-0B, M60-0Q

Workaround

Use a profile that supports more than 1 virtual display head and has at least 1 Gbyte of frame buffer.

NVENC requires at least 1 Gbyte of frame buffer

Description

Using the frame buffer for the NVIDIA hardware-based H.264/HEVC video encoder (NVENC) may cause memory exhaustion with vGPU profiles that have 512 Mbytes or less of frame buffer. To reduce the possibility of memory exhaustion, NVENC is disabled on profiles that have 512 Mbytes or less of frame buffer. Application GPU acceleration remains fully supported and available for all profiles, including profiles with 512 MBytes or less of frame buffer. NVENC support from both Citrix and VMware is a recent feature and, if you are using an older version, you should experience no change in functionality.

The following vGPU profiles have 512 Mbytes or less of frame buffer:

  • Tesla M6-0B, M6-0Q
  • Tesla M10-0B, M10-0Q
  • Tesla M60-0B, M60-0Q

Workaround

If you require NVENC to be enabled, use a profile that has at least 1 Gbyte of frame buffer.

VM running older NVIDIA vGPU drivers fails to initialize vGPU when booted

Description

A VM running older NVIDIA drivers, such as those from a previous vGPU release, will fail to initialize vGPU when booted on a VMware vSphere platform running the current release of GRID Virtual GPU Manager.

In this scenario, the VM boots in standard VGA mode with reduced resolution and color depth. The NVIDIA GRID GPU is present in Windows Device Manager but displays a warning sign, and the following device status:

Windows has stopped this device because it has reported problems. (Code 43)

Depending on the versions of drivers in use, the VMware vSphere VM’s log file reports one of the following errors:

  • A version mismatch between guest and host drivers:
    vthread-10| E105: vmiop_log: Guest VGX version(2.0) and Host VGX version(2.1) do not match
  • A signature mismatch:
    vthread-10| E105: vmiop_log: VGPU message signature mismatch.

Resolution

Install the latest NVIDIA vGPU release drivers in the VM.

Virtual GPU fails to start if ECC is enabled

Description

Tesla M60, Tesla M6, and GPUs based on the Pascal GPU architecture, for example Tesla P100 or Tesla P4, support error correcting code (ECC) memory for improved data integrity. Tesla M60 and M6 GPUs in graphics mode are supplied with ECC memory disabled by default, but it may subsequently be enabled using nvidia-smi. GPUs based on the Pascal GPU architecture are supplied with ECC memory enabled.

However, NVIDIA GRID vGPU does not support ECC memory. If ECC memory is enabled, NVIDIA GRID vGPU fails to start. The following error is logged in the VMware vSphere VM’s log file:

vthread10|E105: Initialization: VGX not supported with ECC Enabled.

Resolution

Ensure that ECC is disabled on all GPUs.

  1. Use nvidia-smi to list the status of all GPUs, and check for ECC noted as enabled on GPUs.
  2. Change the ECC status to off on each GPU for which ECC is enabled by executing the following command:
    nvidia-smi -i id -e 0

    id is the index of the GPU as reported by nvidia-smi.

  3. Reboot the host.

Single vGPU benchmark scores are lower than passthrough GPU

Description

A single vGPU configured on a physical GPU produces lower benchmark scores than the physical GPU run in passthrough mode.

Aside from performance differences that may be attributed to a vGPU’s smaller framebuffer size, vGPU incorporates a performance balancing feature known as Frame Rate Limiter (FRL), which is enabled on all vGPUs. FRL is used to ensure balanced performance across multiple vGPUs that are resident on the same physical GPU. The FRL setting is designed to give good interactive remote graphics experience but may reduce scores in benchmarks that depend on measuring frame rendering rates, as compared to the same benchmarks running on a passthrough GPU.

Resolution

FRL is controlled by an internal vGPU setting. NVIDIA does not validate vGPU with FRL disabled, but for validation of benchmark performance, FRL can be temporarily disabled by adding the configuration parameter pciPassthru0.cfg.frame_rate_limiter in the VM’s advanced configuration options.

Note: This setting can only be changed when the VM is powered off.
  1. Select Edit Settings.
  2. In Edit Settings window, select the VM Options tab.
  3. From the Advanced drop-down list, select Edit Configuration.
  4. In the Configuration Parameters dialog box, click Add Row.
  5. In the Name field, type the parameter name pciPassthru0.cfg.frame_rate_limiter, in the Value field type 0, and click OK.

    Screen capture showing a dialog box that contains advanaced VM configuration options

With this setting in place, the VM’s vGPU will run without any frame rate limit. The FRL can be reverted back to its default setting by setting pciPassthru0.cfg.frame_rate_limiter to 1 or by removing the parameter from the advanced settings.

VMs configured with large memory fail to initialize vGPU when booted

Description

When starting multiple VMs configured with large amounts of RAM (typically more than 32GB per VM), a VM may fail to initialize vGPU. In this scenario, the VM boots in VMware SVGA mode and doesn’t load the NVIDIA driver. The NVIDIA GRID GPU is present in Windows Device Manager but displays a warning sign, and the following device status:

Windows has stopped this device because it has reported problems. (Code 43)

The VMware vSphere VM’s log file contains these error messages:

vthread10|E105: NVOS status 0x29
vthread10|E105: Assertion Failed at 0x7620fd4b:179
vthread10|E105: 8 frames returned by backtrace
 ...
vthread10|E105: VGPU message 12 failed, result code: 0x29
...
vthread10|E105: NVOS status 0x8
vthread10|E105: Assertion Failed at 0x7620c8df:280
vthread10|E105: 8 frames returned by backtrace
...
vthread10|E105: VGPU message 26 failed, result code: 0x8

Resolution

vGPU reserves a portion of the VM’s framebuffer for use in GPU mapping of VM system memory. The reservation is sufficient to support up to 32GB of system memory, and may be increased to accommodate up to 64GB by adding the configuration parameter pciPassthru0.cfg.enable_large_sys_mem in the VM’s advanced configuration options

Note: This setting can only be changed when the VM is powered off.
  1. Select Edit Settings.
  2. In Edit Settings window, select the VM Options tab.
  3. From the Advanced drop-down list, select Edit Configuration.
  4. In the Configuration Parameters dialog box, click Add Row.
  5. In the Name field, type the parameter name pciPassthru0.cfg.enable_large_sys_mem, in the Value field type 1, and click OK.

With this setting in place, less GPU framebuffer is available to applications running in the VM. To accommodate system memory larger than 64GB, the reservation can be further increased by adding pciPassthru0.cfg.extra_fb_reservation in the VM’s advanced configuration options, and setting its value to the desired reservation size in megabytes. The default value of 64M is sufficient to support 64 GB of RAM. We recommend adding 2 M of reservation for each additional 1 GB of system memory. For example, to support 96 GB of RAM, set pciPassthru0.cfg.extra_fb_reservation to 128.

The reservation can be reverted back to its default setting by setting pciPassthru0.cfg.enable_large_sys_mem to 0, or by removing the parameter from the advanced settings.

Resolved Issues

No resolved issues are reported in this release for VMware vSphere.

Tesla P40 cannot be used in pass-through mode

Description

Pass-through mode on Tesla P40 GPUs and other GPUs based on the Pascal architecture does not work as expected. In some situations, after the VM is powered on, the guest OS crashes or fails to boot.

Workaround

Ensure that your GPUs are configured as described in Requirements for Using GPUs Based on the Pascal Architecture in Pass-Through Mode

GRID vGPU utilization in guest VMs is incorrectly reported for vGPUs using a fixed share scheduler

Description

GRID vGPU utilization in guest VMs is incorrectly reported for vGPUs using a fixed share scheduler.

3D engine utilization in guest VMs should be reported as a percentage of the maximum physical GPU utilization the vGPU can consume. For example, a vGPU that is allocated a 25% share of the physical GPU should be reported as fully utilized (100%) when it is consuming 25% of the physical GPU's cycles. However, the utilization for vGPUs using a fixed share scheduler does not correctly account for the vGPU's fixed share of the physical GPU cycles.

Furthermore, the utilization reported by nvidia-smi pmon is inconsistent with the utilization reported by nvidia-smi dmon .

Workaround

Enable the counters by running the following sequence of commands from a command shell:

wmic /namespace:nv path System call enableProcessUtilizationPerfCounter
wmic /namespace:nv path System call enableEncoderSessionsPerfCounter

If you need to disable the counters, run the following sequence of commands from a command shell:

Memory exhaustion can occur with vGPU profiles that have 512 Mbytes or less of frame buffer

Description

Memory exhaustion can occur with vGPU profiles that have 512 Mbytes or less of frame buffer.

This issue typically occurs in the following situations:

  • Full screen 1080p video content is playing in a browser. In this situation, the session hangs and session reconnection fails.
  • Multiple display heads are used with Citrix XenDesktop or VMware Horizon on a Windows 10 guest VM.
  • Higher resolution monitors are used.
  • Applications that are frame-buffer intensive are used.
  • NVENC is in use.

To reduce the possibility of memory exhaustion, NVENC is disabled on profiles that have 512 Mbytes or less of frame buffer.

When memory exhaustion occurs, the NVIDIA host driver reports Xid error 31 and Xid error 43 in the VMware vSphere log file vmware.log in the guest VM’s storage directory.

The following vGPU profiles have 512 Mbytes or less of frame buffer:

  • Tesla M6-0B, M6-0Q
  • Tesla M10-0B, M10-0Q
  • Tesla M60-0B, M60-0Q

The root cause is a known issue associated with changes to the way that recent Microsoft operating systems handle and allow access to overprovisioning messages and errors. If your systems are provisioned with enough frame buffer to support your use cases, you should not encounter these issues.

Workaround

  • Use an appropriately sized vGPU to ensure that the frame buffer supplied to a VM through the vGPU is adequate for your workloads.
  • Monitor your frame buffer usage.
  • If you are using Windows 10, consider these workarounds and solutions:

vGPU VM fails to boot in ESXi 6.5 if the graphics type is Shared

Description

Note: If vSGA is being used, this issue shouldn't be encountered and changing the default graphics type is not necessary.

On VMware vSphere Hypervisor (ESXi) 6.5, after vGPU is configured, VMs to which a vGPU is assigned may fail to start and the following error message may be displayed:

The amount of graphics resource available in the parent resource pool is insufficient for the operation.

The vGPU Manager VIB provides vSGA and vGPU functionality in a single VIB. After this VIB is installed, the default graphics type is Shared, which provides vSGA functionality. To enable vGPU support for VMs in VMware vSphere 6.5, you must change the default graphics type to Shared Direct. If you do not change the default graphics type you will encounter this issue.

Version
