vhost-user enables the communication between a QEMU virtual machine<br>
and other userspace process using the Virtio transport protocol.<br>
It uses a char dev (e.g. Unix socket) for the control plane,<br>
while the data plane based on shared memory.<br>
<br>
The XML looks like:<br>
<br>
<interface type='vhostuser'><br>
<source type='unix' path='/tmp/vhost.sock' mode='server'/><br>
<mac address='52:54:00:3b:83:1a'/><br>
<model type='virtio'/><br>
</interface><br>
<br>
Our use case is the deployment of Snabbswitch in an OpenStack/NFV<br>
environment. Snabbswitch uses a Unix socket to implement the<br>
vhost-user control plane, thus we focused on the support for the<br>
type=unix attribute of the <source> element.<br>
To test it with Snabbswitch, it is necessary to apply the<br>
following patches (respectively from Chen Fan and Michele Paolino):<br>
