-netdev user,id=net0 -device virtio-net-pci,netdev=net0
(Virtual I/O) emerged as the industry-standard solution to this problem, providing a paravirtualized framework that bridges the gap between virtual machine performance and physical hardware speed. virtio
: When the guest OS needs to perform I/O operations, it uses the virtio driver to send requests to the host. The host then performs the actual I/O operations and returns the results to the guest. id=net0 -device virtio-net-pci
In summary, virtio is a powerful I/O virtualization framework that offers high performance, efficiency, and scalability for virtualized environments. Its adoption is widespread in cloud computing, virtual desktop infrastructure, and high-performance computing applications. virtual desktop infrastructure
