VirtIO: The De-Facto Standard for High-Performance Virtual I/O
Virtio is the in Linux‑based clouds. It balances performance, standardization, and maintainability better than either full emulation or direct device assignment. Whether you are running a single VM on your laptop or millions of microVMs in AWS, virtio is quietly delivering the speed you expect. virtio
Benchmark example: virtio‑blk can achieve near‑native disk performance, while emulated IDE often maxes out at ~10–20% of the host’s speed. virtio
is a standardized open interface for virtual machines (VMs) to access host devices (like storage, networking, and consoles). It acts as a paravirtualization layer—a middleman that allows the guest OS to know it is running in a virtual environment and cooperate with the hypervisor for better performance. virtio
