With the release of qemu2.1, you can see that QEMU supports Vhost-user. From the introduction can be seen, this is the original vhost-backend from kernel moved to the userspace, this and the original virtio structure what is the difference. And this feature has brought about improvements. Virtio In the virtual machine, you can simulate the E1000 network card through QEMU, such classic network card is a gen
