It implements the control plane needed +to establish virtqueue sharing with a user space process on the same host. It +uses communication over a Unix domain socket to share file descriptors in the +ancillary data of the message. + +The protocol defines 2 sides of the communication, master and slave.

Slave is the +consumer of the virtqueues. + +In the current implementation QEMU is the Master, and the Slave is intended to +be a software Ethernet switch running in user space, such as Snabbswitch. + +Master and slave can be either a client (i.e. connecting) or server (listening) +in the socket communication. + +Message Specification +--------------------- + +Note that all numbers are in the machine native byte order.
