However, it is not a "plug-and-play" process. It requires specific hardware and precise configuration of the Linux host. 1. Hardware Requirements & Compatibility
In virt-manager or your Libvirt XML, you must add the PCI devices for the GPU. Ensure you also pass through the GPU Audio device, or you may experience stuttering or crashes. 4. Common Pitfalls osx-kvm-gpu-passthrough
Must support IOMMU . Ideally, the GPU you want to pass through should be in its own isolated IOMMU group to avoid "passing through" other critical components like your USB controller or NVMe drive by accident. 2. Preparing the Host (Linux) However, it is not a "plug-and-play" process
Before touching the VM, you must "isolate" the GPU so the Linux host doesn't try to use it. Common Pitfalls Must support IOMMU
Most modern AMD cards work out of the box because Apple uses them in real Macs. Models like the are top choices.
Use lspci -nn to find the Vendor and Device IDs for your GPU and its associated audio controller.
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
