Technical Details

对于virtio网络设备来说，它至少有两个virtqueue(如果协商了VIRTIO_NET_F_MQ则可以创建多个队列,详见VirtIO SPEC中5.1.2 )，一个用于TX(send_queue)，另一个用于RX(receive_queue)，TX和RX队列中都包含了virtqueue和scatterlist[]。

virtio 并没有提供多种设备模拟机制（针对网络、块和其他驱动程序），而是为这些设备模拟提供一个通用的前端，从而标准化接口和增加代码的跨平台重用。. 在传统的完全虚拟化环境中，虚拟化系统必须捕捉这些请求，然后模拟物理硬件的行为。. 尽管这样做 ...
