<p className="mb-4">

<strong>Why it's important:</strong> IOMMU and VFIO support enables near-native performance for PCI devices (like GPUs or network cards) in virtual machines. This is crucial for high-performance virtualization scenarios, such as GPU-accelerated workloads or network-intensive applications. It allows VMs to directly access hardware, bypassing the hypervisor, which significantly improves performance and reduces latency.
