- Vmware workstation 12 unrecoverable error (vcpu-0) free
When NVIDIA vGPU Manager is used with guest VM drivers from a different release within the same branch or from the previous branch, the combination supports only the features, hardware, and software including guest OSes that are supported on both releases.
For example, if vGPU Manager from release In displayless mode, local physical display connectors are disabled. 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.
Only the following GPUs support the displaymodeselector tool:. If you are unsure which mode your GPU is in, use the gpumodeswitch tool to find out the mode. For more information, refer to gpumodeswitch User Guide. With ESXi 6. Starting with release 6. Release 6. This release supports the management software and virtual desktop software releases listed in the table. The supported guest operating systems depend on the hypervisor software version.
No bit guest operating systems are supported. Since See Note 1. To support applications and workloads that are compute or graphics intensive, multiple vGPUs can be added to a single VM. If you upgraded to VMware vSphere 6. Linux only. Unified memory is not supported on Windows. Supported DLSS versions: 2. Version 1. Supported VMware vCenter Server releases: 7. This limitation affects any remoting tool where H.
Most supported remoting tools fall back to software encoding in such scenarios. This policy setting encodes only actively changing regions of the screen for example, a window in which a video is playing. Provided that the number of pixels along any edge of the actively changing region does not exceed , H. C-series vGPU types are not available. As a result, the number of channels allocated to each vGPU is increased. On all GPUs that support ECC memory and, therefore, dynamic page retirement, additional frame buffer is allocated for dynamic page retirement.
The amount of frame buffer in Mbytes that is reserved for the higher compression overhead in vGPU types with 12 Gbytes or more of frame buffer on GPUs based on the Turing architecture. For all other vGPU types, compression-adjustment is 0. These issues occur when the applications demand more frame buffer than is allocated to the vGPU.
To reduce the possibility of memory exhaustion, vGPU profiles with Mbytes or less of frame buffer support only 1 virtual display head on a Windows 10 guest OS. Use a profile that supports more than 1 virtual display head and has at least 1 Gbyte of frame buffer.
To reduce the possibility of memory exhaustion, NVENC is disabled on profiles that have Mbytes or less of frame buffer. Application GPU acceleration remains fully supported and available for all profiles, including profiles with 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. On servers with 1 TiB or more of system memory, VM failures or crashes may occur.
However, support for vDGA is not affected by this limitation. The guest driver is from a release in a branch two or more major releases before the current release, for example release 9. 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.
The FRL can be reverted back to its default setting by setting pciPassthru0. 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. To accommodate system memory larger than 64GB, the reservation can be further increased by adding pciPassthru0.
We recommend adding 2 M of reservation for each additional 1 GB of system memory. The reservation can be reverted back to its default setting by setting pciPassthru0. Only resolved issues that have been previously noted as known issues or had a noticeable user impact are listed. No resolved issues are reported in this release for VMware vSphere. When this issue occurs, error messages that indicate that the Virtual GPU Manager process crashed are written to the log file vmware. Applications running in a VM request memory to be allocated and freed by the vGPU manager plugin, which runs on the hypervisor host.
When an application requests the vGPU manager plugin to free previously allocated memory, some of the memory is not freed. Some applications request memory more frequently than other applications. If such applications run for a long period of time, for example for two or more days, the failure to free all allocated memory might cause the hypervisor host to run out of memory. As a result, memory allocation for applications running in the VM might fail, causing the applications and, sometimes, the VM to hang.
As a result, the validation check in the service fails, which causes the client to fail to acquire a license. This issue occurs because starting with Windows Server , the required codecs are not included with the OS and are not available through the Microsoft Store app.
As a result, hardware decoding is not available for viewing YouTube videos or using collaboration tools such as Google Meet in a web browser. If an application or a VM hangs after a long period of usage, restart the VM every couple of days to prevent the hypervisor host from running out of memory. If you encounter this issue after the VM is configured, use one of the following workarounds:.
After the session freezes, the VM must be rebooted to recover the session. These mappings depend on the number and type of applications running in the VM. To employ this workaround, set the vGPU plugin parameter pciPassthru0. Only VMware vCenter Server 7. Upgrade VMware vCenter Server to release 7. Only the reported frame rate is incorrect. The actual encoding of frames is not affected. When this issue occurs, XID error 31 is written to the log files on the destination hypervisor host.
This issue affects migration from a host that is running a vGPU manager 11 release before Upgrade the host that is running a vGPU manager 11 release to release When this issue occurs, the following messages are written to the log file on the hypervisor host:. This issue is resolved in the latest For more information, refer to the documentation for the version of VMware Horizon that you are using:. 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.
Ensure that sufficient frame buffer is available for all the virtual displays that are connected to a vGPU by changing the configuration in one of the following ways:.
After the migration, the destination host and VM become unstable. Depending on the host configurations, the following messages might also be written to the log file:.
After a Teradici Cloud Access Software session has been idle for a short period of time, the session disconnects from the VM. This issue affects only Linux guest VMs.
This issue is caused by the omission of version information for the vGPU manager from the configuration information that GPU Operator requires. This issue occurs if the driver is upgraded by overinstalling the new release of the driver on the current release of the driver while the nvidia-gridd service is running in the VM. When a window is dragged across the desktop in a Citrix Virtual Apps and Desktops session, corruption of the session in the form of residual window borders occurs.
This issue affects only Citrix Virtual Apps and Desktops version 7 When this issue occurs, the VM becomes unusable and clients cannot connect to the VM even if only a single display is connected to it. When this issue occurs, the error One or more devices pciPassthru0 required by VM vm-name are not available on host host-name is reported on VMware vCenter Server. Unable to allocate video memory. 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.
When VMware Horizon is used with the Blast Extreme display protocol, frame buffer consumption increases over time after multiple disconnections from and reconnections to a VM.
This issue occurs even if the VM is in an idle state and no graphics applications are running. Computer Management shows problems with the primary display device. After multiple VMs configured with vGPU on a single hypervisor host are migrated simultaneously, the remote desktop session freezes with an assertion failure and XID error It does not occur if only a single VM is migrated. 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. Stop and restart the Xorg service and nv-hostengine on the ESXi host. Wait for 1 second to allow nv-hostengine to stop.
