Virtio «CERTIFIED»

The Virtio architecture consists of two primary components: the Virtio driver and the Virtio device. The Virtio driver is a software component that runs within the guest operating system and provides a standardized interface for accessing virtualized devices. The Virtio device, on the other hand, is a software or hardware component that emulates a physical device and provides the actual functionality.

The key to VirtIO's efficiency is the vring (virtio ring) structure. It is a standardized ring buffer in shared memory that holds data buffers. Because both the guest and host can access this memory, data does not need to be copied multiple times, drastically reducing CPU overhead. Core Components and Types of VirtIO Devices virtio

Traditional virtualization (full emulation) has a major drawback: . The Virtio architecture consists of two primary components:
