A detailed view of the vhost user protocol and its implementation in OVS DPDK, qemu and virtio-net Overview: How OVS DPDK and qemu communicate via the vhost user protocol The vhost user protocol consists of a control path and a data path. All control information is exchanged via a Unix soc...
QEMU 启动时连接 main socket,如果 vhost-user 提供了 VHOST_USER_PROTOCOL_F_SLAVE_REQ 特性,则 qemu 创建第二条 socket,并将其传给 vhost-user,以便 vhost-user 连接此 socket,并通过该 socket 发送 IOTLB 同步消息。 QEMU 与 vhost-user 之间的协商结束后,它们之间会保持两条 socket。一条用来做 virtio ...
2. qemu启动时,它将连接到主套接字,如果vhost提供了VHOST_USER_PROTOCOL_F_SLAVE_REQ功能,则当主机(OvS)中的DPDK应用程序启动时,它将创建一个套接字(以服务器模式使用),用于与qemu进行virtio相关的协商。 3. 当QEMU <-> vhost-library协商结束时,它们之间共享两个套接字。一个套接字用于virtio配置,另一个...

The reference implementation of the vhost client/backend concept is calledvapp. This can serve as a test case for the vhost-user protocol and as a way to boostrap implementation of a new client or server. The source for Vapp is in the Virtual Open Systems public github repository: ...
The previous blogs (see end of post) included the solution overview, a technical deep dive and a hands on post introducing the reader to the virtio-networking ecosystem including an overview of the basic building blocks (kvm, qemu, libvirt), the vhost protocol and the vhost-net/virtio-net ...
