Is required for all the GPUs is 4⨯128 GiB, which equals 512 GiB. Multiply the total BAR1 memory usage for each GPU by the number of GPUs that youĪre assigning in pass-through mode to the VM.įor example, if you are assigning four GPUs to a VM, the amount of MMIO space that
In this example, the total BAR1 memory usage for each GPU is 128 GiB.
On the hypervisor host, get the total BAR1 memory usage for each GPU. If you are assigning multiple GPUs in pass-through mode to a single VM, ensure that youĪllocate enough MMIO space to the VM for all the GPUs.Ĭalculate the amount of MMIO space that is required for all the GPUs that you want to Requirements for Assigning Multiple GPUs in Pass-Through Mode to a Single VM
