Application or vGPU VM crashes when multiple application instances are launched#

Description#

When multiple application instances are launched on a legacy vGPU that is allocated only a fraction of the physical GPU’s frame buffer, the application or VM to which the vGPU is assigned crashes but the guest VM remains accessible… A legacy NVIDIA vGPU does not support single root I/O virtualization (SR-IOV). This issue does not affect NVIDIA vGPUs that support SR-IOV.

When this issue occurs, the following error message is written to the vmware.log file:

vmiop_log: (0x0): VGPU message 7 failed

This issue occurs when the plugin for legacy NVIDIA vGPUs creates more BAR1 mappings than the hypervisor allows a VM to create. These mappings depend on the number and type of applications running in the VM.
