The most reliable way to build the VM base is using the OSX-KVM project on GitHub .
Edit your GRUB configuration ( /etc/default/grub ) and add intel_iommu=on or amd_iommu=on to the kernel parameters. osx-kvm-gpu-passthrough
Instruct the kernel to use the vfio-pci driver for those IDs at boot. This prevents your Linux desktop from "grabbing" the card. 3. The OSX-KVM Setup The most reliable way to build the VM
Before touching the VM, you must "isolate" the GPU so the Linux host doesn't try to use it. This prevents your Linux desktop from "grabbing" the card
Sometimes the VM needs a clean copy of the GPU's Video BIOS (vBIOS). You can download this from TechPowerUp and point to it in your XML config using .
Success starts with your hardware. macOS has very strict driver support compared to Windows or Linux. This is the most critical factor. AMD (Recommended):
However, it is not a "plug-and-play" process. It requires specific hardware and precise configuration of the Linux host. 1. Hardware Requirements & Compatibility
