April 12, 2022 - Microsoft Hyper-V, Citrix XenServer and VMware ESXi all support pass-through mode. The alternative means to virtualize GPUs is the vGPU mode. This approach creates a time-sharing environment that enables multiple VMs to share the GPU's resources. For example, if a GPU is virtualized into 10 vGPUs, and each vGPU is assigned to one of 10 VMs, each VM would have access to the GPU -- and its CUDA cores -- for 10% of the time."
