WebTo use vhost-user-client ports, you must first add said ports to the switch. Like DPDK vhost-user ports, DPDK vhost-user-client ports can have mostly arbitrary. However, the name given to the port does not govern the name of the socket device. Instead, this must be configured by the user by way of a vhost-server-path option. Webvhost user can run in 2 modes: vhostuser-client - qemu is the server, the software switch is the client vhostuser - the software switch is the server, qemu is the client vhost user is based on the vhost architecture and implements all features in user space.
WebVhost leverages the registered DMA channels to free CPU from memory copy operations in data path. A set of async data path APIs are defined for DPDK applications to make use of the async capability. Only packets enqueued/dequeued by async APIs are processed through the async data path.
