Some cards, in particular VR-ready nvidia GPUs and the new 20 series GPUs will have more devices you’ll need to pass, so refer to the full output to make sure you got all of them. You need to use every device ID associated with your device, and most GPUs have both an audio controller and VGA. Look for the device ids for each device you intend to pass through, for example, my GTX 1070 is listed as and for the HDMI audio. You can also just run lspci -nnk to get all attached devices, in case you want to pass through something else, like an NVMe drive or a usb controller. Run lspci -nnk | grep "VGA\|Audio" - this will output a list of installed devices relevant to your GPU. Systemd-boot distributions like Pop!OS will have to do things differently. We’ll be covering Grub 2 here because it’s the most common. The best way of going about this is changing your kernel commandline boot options, which you do by editing your bootloader’s configuration files. Once you’ve enabled these features, you need to tell Linux to use them, as well as what PCI devices to reserve for your vm. These features are usually titled something like “virtualization support” “VT-x” or “SVM” - IOMMU is usually labelled “VT-d” or “AMD-Vi” if not just “IOMMU support.” The exact name and locations varies by vendor and motherboard. Provided you have hardware that supports this process, it should be relatively straightforward.įirst, you want to enable virtualization extensions and IOMMU in your uefi. Vega and Fiji seem especially susceptible) 300 series cards may also have Mac OS specific compatibility issues.
