How far along are you in your setup—have you already in the host OS, or are you still selecting hardware ?
Edit your GRUB configuration ( /etc/default/grub ) and add intel_iommu=on or amd_iommu=on to the kernel parameters. osx-kvm-gpu-passthrough
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 How far along are you in your setup—have
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) Ensure you also pass through the GPU Audio
A GPU gives you a display, but you still need a smooth mouse and keyboard. Passing through an entire USB Controller is better than passing through individual HID devices for zero latency. 5. Why Bother?
Generally a no-go for modern macOS. Only very old Kepler-based cards (like the Go to product viewer dialog for this item. ) work natively. Newer RTX cards have no drivers for macOS. CPU: You need a processor that supports Intel VT-d Go to product viewer dialog for this item. or .
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
