Virtual GPU Software R384 for VMware vSphere Release Notes
Release information for all users of NVIDIA virtual GPU software and hardware on VMware vSphere.
These Release Notes summarize current status, information on validated platforms, and known issues with NVIDIA vGPU software and associated hardware on VMware vSphere.
The releases in this release family of NVIDIA vGPU software include the software listed in the following table:
Software | 5.0 | 5.1 | 5.2 | 5.3 | 5.4 |
---|---|---|---|---|---|
NVIDIA Virtual GPU Manager for the VMware vSphere releases listed in Hypervisor Software Releases | 384.73 | 384.99 | 384.111 | 384.137 | 384.155 |
NVIDIA Windows driver | 385.41 | 385.90 | 386.09 | 386.37 | 386.57 |
NVIDIA Linux driver version | 384.73 | 384.99 | 384.111 | 384.137 | 384.155 |
If you install the wrong package for the version of VMware vSphere you are using, NVIDIA Virtual GPU Manager will fail to load.
The releases of the vGPU Manager and guest VM drivers that you install must be compatible. Different versions of the vGPU Manager and guest VM driver from within the same main release branch can be used together. For example, you can use the vGPU Manager from release 5.1 with guest VM drivers from release 5.0. However, versions of the vGPU Manager and guest VM driver from different main release branches cannot be used together. For example, you cannot use the vGPU Manager from release 5.1 with guest VM drivers from release 4.4. See VM running older NVIDIA vGPU drivers fails to initialize vGPU when booted.
This requirement does not apply to the NVIDIA vGPU software license sever. All releases of NVIDIA vGPU software are compatible with all releases of the license server.

This release family of NVIDIA vGPU software provides support for several NVIDIA GPUs on validated server hardware platforms, VMware vSphere hypervisor software versions, and guest operating systems. It also supports the version of NVIDIA CUDA Toolkit that is compatible with R384 drivers.
2.1. Supported NVIDIA GPUs and Validated Server Platforms
This release of NVIDIA vGPU software provides support for the following NVIDIA GPUs on VMware vSphere, running on validated server hardware platforms:
- Tesla M6
- Tesla M10
- Tesla M60
- Tesla P4
- Tesla P6
- Tesla P40
- Tesla P100 (vSGA is not supported.)
- Since 5.1: Tesla P100 12GB (vSGA is not supported.)
For a list of validated server platforms, refer to NVIDIA GRID Certified Servers.
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.
Requirements for Using vGPU on GPUs Requiring 64 GB of MMIO Space with Large-Memory VMs
Some GPUs require 64 GB of MMIO space. When a vGPU on a GPU that requires 64 GB of MMIO space is assigned to a VM with 32 GB or more of memory on ESXi 6.0 Update 3 and later, or ESXi 6.5 and later updates, the VM’s MMIO space must be increased to 64 GB. For more information, see VMware Knowledge Base Article: VMware vSphere VMDirectPath I/O: Requirements for Platforms and Devices (2142307).
The following GPUs require 64 GB of MMIO space:
- Tesla P6
- Tesla P40
Requirements for Using GPUs Based on the Pascal Architecture in Pass-Through Mode
- The Tesla P100 and Tesla P6 GPUs require 32 GB of MMIO space in pass-through mode.
- The Tesla P40 GPU requires 64 GB of MMIO space in pass-through mode.
- Pass through of GPUs with large BAR memory settings has some restrictions on VMware ESXi:
- The guest OS must be a 64-bit OS.
- 64-bit MMIO and EFI boot must be enabled for the VM.
- The guest OS must be able to be installed in EFI boot mode.
- The Tesla P100 and Tesla P6 require ESXi 6.0 Update 1 and later, or ESXi 6.5 and later.
- Because it requires 64 GB of MMIO space, the Tesla P40 requires ESXi 6.0 Update 3 and later, or ESXi 6.5 and later.
As a result, the VM’s MMIO space must be increased to 64 GB as explained in VMware Knowledge Base Article: VMware vSphere VMDirectPath I/O: Requirements for Platforms and Devices (2142307).

2.4. NVIDIA CUDA Toolkit Version Support
The releases in this release family of NVIDIA vGPU software support NVIDIA CUDA Toolkit 9.0.
For more information about NVIDIA CUDA Toolkit, see CUDA Toolkit 9.0 Documentation.
Known product limitations for this release of NVIDIA vGPU software are described in the following sections.
3.1. 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.
3.2. 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.
3.3. VM failures or crashes on servers with 1 TB or more of system memory
Description
Support for vGPU and vSGA is limited to servers with less than 1 TB of system memory. On servers with 1 TB or more of system memory, VM failures or crashes may occur. For example, when Citrix XenDesktop is used with a Windows 7 guest OS, a blue screen crash may occur. However, support for vDGA is not affected by this limitation.
This limitation applies only to systems with supported GPUs based on the Maxwell architecture: Tesla M6, Tesla M10, and Tesla M60.
Resolution
-
Limit the amount of system memory on the server to 1 TB minus 16 GB by setting
memmapMaxRAMMB
to 1032192, which is equal to 1048576 minus 16384. -
Reboot the server.
If the problem persists, contact your server vendor for the recommended system memory configuration with NVIDIA GPUs.
3.4. VM running older NVIDIA vGPU drivers fails to initialize vGPU when booted
Description
A VM running a version of the NVIDIA guest VM drivers from a previous main release branch, for example release 4.4, will fail to initialize vGPU when booted on a VMware vSphere platform running the current release of Virtual GPU Manager.
In this scenario, the VM boots in standard VGA mode with reduced resolution and color depth. The NVIDIA virtual 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 current NVIDIA guest VM driver in the VM.
3.5. 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 vGPU does not support ECC memory. If ECC memory is enabled, NVIDIA 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.
Before you begin, ensure that NVIDIA Virtual GPU Manager is installed on your hypervisor.
- Use nvidia-smi to list the status of all GPUs, and check for ECC noted as enabled on GPUs.
# nvidia-smi -q ==============NVSMI LOG============== Timestamp : Tue Dec 19 18:36:45 2017 Driver Version : 384.99 Attached GPUs : 1 GPU 0000:02:00.0 [...] Ecc Mode Current : Enabled Pending : Enabled [...]
- Change the ECC status to off on each GPU for which ECC is enabled.
- If you want to change the ECC status to off for all GPUs on your host machine, run this command:
# nvidia-smi -e 0
- If you want to change the ECC status to off for a specific GPU, run this command:
# nvidia-smi -i id -e 0
id is the index of the GPU as reported by nvidia-smi.
This example disables ECC for the GPU with index
0000:02:00.0
.# nvidia-smi -i 0000:02:00.0 -e 0
- If you want to change the ECC status to off for all GPUs on your host machine, run this command:
- Reboot the host.
- Confirm that ECC is now disabled for the GPU.
# nvidia-smi -q ==============NVSMI LOG============== Timestamp : Tue Dec 19 18:37:53 2017 Driver Version : 384.99 Attached GPUs : 1 GPU 0000:02:00.0 [...] Ecc Mode Current : Disabled Pending : Disabled [...]
If you later need to enable ECC on your GPUs, run one of the following commands:
- If you want to change the ECC status to on for all GPUs on your host machine, run this command:
# nvidia-smi -e 1
- If you want to change the ECC status to on for a specific GPU, run this command:
# nvidia-smi -i id -e 1
id is the index of the GPU as reported by nvidia-smi.
This example enables ECC for the GPU with index
0000:02:00.0
.# nvidia-smi -i 0000:02:00.0 -e 1
After changing the ECC status to on, reboot the host.
3.6. Single vGPU benchmark scores are lower than pass-through GPU
Description
A single vGPU configured on a physical GPU produces lower benchmark scores than the physical GPU run in pass-through mode.
Aside from performance differences that may be attributed to a vGPU’s smaller frame buffer size, vGPU incorporates a performance balancing feature known as Frame Rate Limiter (FRL). On vGPUs that use the best-effort scheduler, FRL is enabled. On vGPUs that use the fixed share or equal share scheduler, FRL is disabled.
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 pass-through GPU.
Resolution
FRL is controlled by an internal vGPU setting. On vGPUs that use the best-effort scheduler, 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.
This setting can only be changed when the VM is powered off.
- Select Edit Settings.
- In Edit Settings window, select the VM Options tab.
- From the Advanced drop-down list, select Edit Configuration.
- In the Configuration Parameters dialog box, click Add Row.
- In the Name field, type the parameter name
pciPassthru0.cfg.frame_rate_limiter
, in the Value field type 0, and click OK.
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.
3.7. 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 vGPU software 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
This setting can only be changed when the VM is powered off.
- Select Edit Settings.
- In Edit Settings window, select the VM Options tab.
- From the Advanced drop-down list, select Edit Configuration.
- In the Configuration Parameters dialog box, click Add Row.
- 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.
Only resolved issues that have been previously noted as known issues or had a noticeable user impact are listed. The summary and description for each resolved issue indicate the effect of the issue on NVIDIA vGPU software before the issue was resolved.
Issues Resolved in Release 5.0
No resolved issues are reported in this release for VMware vSphere.
Issues Resolved in Release 5.1
Bug ID | Summary and Description |
---|---|
1967625 | NVIDIA 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. 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. |
Issues Resolved in Release 5.2
Bug ID | Summary and Description |
---|---|
200359618 | On GPUs based on the Pascal architecture, Ubuntu 16.04 VMs run slowly after acquiring a license 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 vGPU or pass-through GPU run noticeably faster. |
200359624 | The Apply button is disabled after change to unlicensed mode 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. |
Issues Resolved in Release 5.3
Bug ID | Summary and Description |
---|---|
200334648 | Multiple display heads are not detected by Ubuntu 14.04 guest VMs After an Ubuntu 14.04 guest VM has acquired a license, multiple display heads connected to the VM are not detected. |
2075467 | The displays flicker each time a license is requested or renewed in Linux guest VMs Whenever a license is requested or renewed in Linux guest VMs, the displays are reconfigured and rescanned. Rescanning the displays causes the remoting solution to momentarily drop the connection and, as a result, the displays flicker. |
200376678 | The license expires prematurely in Linux guest VMs 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. |
200391532 | Issues in remote desktop sessions if a license is acquired after a session is started 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. |

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.

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

6.19. 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.

6.20. 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:
-
Use a profile that has 1 Gbyte of frame buffer.
-
Optimize your Windows 10 resource usage.
To obtain information about best practices for improved user experience using Windows 10 in virtual environments, complete the NVIDIA GRID vGPU Profile Sizing Guide for Windows 10 download request form.
Additionally, you can use the VMware OS Optimization Tool to make and apply optimization recommendations for Windows 10 and other operating systems.

6.23. VMs configured with NVIDIA vGPU must not be on a host in a VMware DRS cluster
Description
The ESXi host on which VMs configured with NVIDIA vGPU reside must not be a member of a VMware Distributed Resource Scheduler (DRS) cluster. The installer for the NVIDIA driver for NVIDIA vGPU software cannot locate the NVIDIA vGPU software GPU card on a host in a VMware DRS Cluster. Any attempt to install the driver on a VM on a host in a DRS cluster fails with the following error:
NVIDIA Installer cannot continue
This graphics driver could not find compatible graphics hardware.
Furthermore, you cannot overcome this limitation by configuring a VM with NVIDIA vGPU and installing the driver on the VM on a host outside a DRS cluster and moving the host into the DRS cluster after configuring it.
Workaround
Move each VM configured with NVIDIA vGPU to a host outside the DRS cluster.
- Remove NVIDIA Virtual GPU Manager from the host in the DRS cluster.
- Create a cluster of VMware ESXi hosts outside the DRS domain.
- Install the NVIDIA Virtual GPU Manager on an ESXi host in the cluster that you created in the previous step.
- Create a vSphere VM for use with NVIDIA vGPU.
- Configure the vSphere VM with NVIDIA vGPU.
- Boot the vSphere VM and install the NVIDIA driver for NVIDIA vGPU.
