VMware Linux guest kernel module. The vmware-specific driver is really only the files prefixed with vmwgfx. To get the latest code from Git:. The libxatracker library is used exclusively by the X server to do render, copy and video acceleration:. First check if your system is or bit. First make sure that any old version of this kernel module is removed from the system by issuing.
Select the correct profile from the drop-down menu. Press I and change. For the guest operating system, perform the following installations and configurations. Before updating Windows in the VM, install all required versions of Microsoft runtimes that are patched by Windows Update and that can run side by side in the image. For example, install:. You might need to first manually install Windows Update Client for Windows 8.
For a Red Hat Enterprise Linux guest operating system, install and configure as follows. During the creation of a new server farm in Horizon, configuring a farm for 3D is the same as configuring a normal farm.
During the creation of a new desktop pool in Horizon, configure the pool as normal until you reach the Pool Settings section. Automatic uses hardware acceleration if there is a capable, and available, hardware GPU in the host that the VM is starting in. Hardware uses only hardware-accelerated GPUs.
If a hardware GPU is not present in a host, the VM will not start, or you will not be able to perform a live vSphere vMotion migration to that host. This setting can be used to guarantee that a VM will always use hardware 3D rendering when a GPU is available, but that strategy in turn limits the VM to running only on those hosts that have hardware GPUs.
With Horizon 7 version 7. Following are some useful tools to monitor resources when employing graphics acceleration. To get a summary of the vGPUs currently running on each physical GPU in the system, run nvidia-smi without additional arguments. Thu Oct 5 A Volatile Uncorr. For each vGPU, the usage statistics in the following table are reported once every second.
Try these troubleshooting techniques to address general problems or a specific symptom. Often, an issue with the GPU is identified in the vmkernel. To make sure that the graphics adapter is installed correctly, run the following command on the ESXi host:. The output should resemble the following example, even if some of the particulars differ:. If you installed a second, lower-end GPU in the server, it is possible that the order of the cards in the PCIe slots will choose the higher-end card for the ESXi console session.
If the correct devices were present when you tried the previous troubleshooting methods, view the Xorg log file to see if there is an obvious issue. This section describes specific issues that could arise in graphics acceleration deployments, and presents probable solutions. If you get a vSphere error about sched. Note : The number in quotes, in this example, , must match the amount of configured VM memory.
Use a profile that supports more than one virtual display head and has at least 1 GB of frame buffer. To reduce the possibility of memory exhaustion, vGPU profiles with MB or less of frame buffer support only one virtual display head on a Windows 10 guest OS. Turn off the frame rate limiter FRL by adding the configuration parameter pciPassthru0. The FRL setting is designed to give a good interactive remote graphics experience but might reduce scores in benchmarks that depend on measuring frame-rendering rates, as compared to the same benchmarks running on a pass-through GPU.
Windows has stopped this device because it has reported problems. Code Add the configuration parameter pciPassthru0. If you do not change the default graphics type you will encounter this issue.
When memory usage is monitored from inside the VM, no memory usage alarm is shown. For VMware vSphere releases before 6. Any attempt to install the driver on a VM on a host in an automated DRS cluster fails with the following error:. Ensure that the automation level of the DRS cluster is set to Manual.
Click Apply to accept the configuration. The additional vGPU devices are present in Windows Device Manager but display a warning sign, and the following device status:.
This is not a currently supported configuration for vGPU. If multiple VMs are started simultaneously, vSphere may not adhere to the placement policy currently in effect. Sleep is not supported on vGPU and attempts to use it will lead to undefined behavior.
Installing the VMware Horizon agent will disable the Sleep option. For example, on a server configured with G of memory, these errors may occur if vGPU-enabled VMs are assigned more than G of memory. Reduce the total amount of system memory assigned to the VMs. On a system running a maximal configuration, that is, with the maximum number of vGPU VMs the server can support, some VMs might fail to start post a reset or restart operation.
The GPU utilization remains high for the duration of the Horizon session even if there are no active applications running on the VM.

Issues occur when the channels allocated to a vGPU are exhausted. VM failures or crashes on servers with 1 TiB or more of system memory. VMs configured with large memory fail to initialize vGPU when booted. Windows R2 licensed clients cannot acquire licenses from a DLS instance.
VM fails after a second vGPU is assigned to it. When a licensed client deployed by using VMware instant clone technology is destroyed, it does not return the license. A licensed client might fail to acquire a license if a proxy is set. Disconnected sessions cannot be reconnected or might be reconnected very slowly with NVWMI installed. Windows VM crashes during Custom Advanced driver upgrade. NVML fails to initialize with unknown error. Citrix Virtual Apps and Desktops session corruption occurs in the form of residual window borders.
Suspend and resume between hosts running different versions of the vGPU manager fails. On Linux, a VMware Horizon 7. On Linux, the frame rate might drop to 1 after several minutes.
Remote desktop session freezes with assertion failure and XID error 43 after migration. Citrix Virtual Apps and Desktops session freezes when the desktop is unlocked. Black screens observed when a VMware Horizon session is connected to four displays.
Host core CPU utilization is higher than expected for moderate workloads. Frame capture while the interactive logon message is displayed returns blank screen. VMware vMotion fails gracefully under heavy load. View session freezes intermittently after a Linux VM acquires a license. When the scheduling policy is fixed share, GPU utilization is reported as higher than expected. GPU resources not available error during VMware instant clone provisioning. Tesla P40 cannot be used in pass-through mode.
On Linux, 3D applications run slowly when windows are dragged. Licenses remain checked out when VMs are forcibly powered off. ESXi 6. Updates in Release Hardware and Software Support Introduced in Release Feature Support Withdrawn in Release The base VMware vSphere 7. Tesla M10 vCS is not supported. Tesla M60 vCS is not supported. Note: To determine the total BAR1 memory, run nvidia-smi -q on the host. Supported Management Software and Virtual Desktop Software Releases This release supports the management software and virtual desktop software releases listed in the table.
Releases earlier than 6. Limitations Only direct connections are supported. NVSwitch is not supported. Only time-sliced vGPUs are supported.
PCIe is not supported. SLI is not supported. Note: Unified memory is disabled by default. If used, you must enable unified memory individually for each vGPU that requires it by setting a vGPU plugin parameter. Therefore, if the creation of VM templates includes driver installation, the template should be created from a VM that is configured with a supported GPU while the driver is being installed.
Workaround Use H. Note: A Citrix issue prevents the H. Until this issue is resolved, switch to using H. Total frame buffer for vGPUs is less than the total frame buffer on the physical GPU Some of the physical GPU's frame buffer is used by the hypervisor on behalf of the VM for allocations that the guest OS would otherwise have made in its own frame buffer.
For example, these issues may occur with the Adobe Photoshop and LuxMark OpenCL Benchmark applications: When the image resolution and size are changed in Adobe Photoshop, a program error may occur or Photoshop may display a message about a problem with the graphics hardware and a suggestion to disable OpenCL.
Workaround Use a profile that supports more than 1 virtual display head and has at least 1 Gbyte of frame buffer. Reboot the server. A guest VM driver is incompatible with the current release of Virtual GPU Manager in either of the following situations: The guest driver is from a release in a branch two or more major releases before the current release, for example release 9.
Performance difference: 2. Tesla M Highest graphics composite in four VMs: 2. Lowest graphics composite in four VMs: 1. PC and server manufacturers may vary configurations, yielding different results.
