That is, you must enable EFI in the VM and then do an EFI installation of the Guest OS.Įditing the PCI Device Availability on the Host ServerĪn installed PCI-compatible GPU hardware device is initially recognized by the vSphere hypervisor at server boot time without having any specific drivers that are installed into the hypervisor. To access these large memory mappings, connect to VMware site Guest OS must boot with EFI. Note: These settings are needed only if you BIOS boot mode is set to UEFI, if its Legacy or BIOS mode you can ignore the below. To enable this, find the host BIOS setting for "memory mapped I/O above 4 GB" and enable it. Your host BIOS must be configured to support the large memory regions needed by these high-end PCI devices.
You should follow the instructions in this article to enable them for use in passthrough mode within a virtual machine. As a rule, cards that require more than 16 GB of memory mapping are high-end cards. Follow VMware KB 1010789 published instructions to enable passthrough devices under vSphere. This article is only relevant if your PCI device maps memory regions whose sizes total more than 16 GB. This section describes all these requirements. Your host BIOS must be configured correctly to enable Nvidia GPU for passthrough, and the virtual machine that is destined to run these accelerated workloads must meet specific requirements.
