1. Executive Summary VirtIO (Virtual I/O) is a standardized interface for paravirtualized devices in KVM/QEMU-based virtualization. The VirtIO driver ISO provides Windows and other guest operating systems with the necessary drivers to recognize virtual network, block (disk), and memory balloon devices. Using these drivers significantly improves disk I/O and network performance compared to emulated legacy hardware.
