> -Vhost-user uses Unix domain sockets for passing messages. This means the
> DPDK vhost-user implementation has two options:
> -
> -* DPDK vhost-user acts as the server:
> -  DPDK will create a Unix domain socket server file and listen for connections
> from the frontend.
> -  Note, this is the default mode, and the only mode before DPDK v16.07.
> -
> -* DPDK vhost-user acts as the client:
> -  Unlike the server mode, this mode doesn't create the socket file;it just tries
> to connect to the server (which responses to create the file instead).
> -  When the DPDK vhost-user application restarts, DPDK vhost-user will try to
> connect to the server again. This is how the "reconnect" feature works.
> -  When DPDK vhost-user restarts from an normal or abnormal exit (such as a
> crash), the client mode allows DPDK to establish the connection again. Note
> -  that QEMU version v4.2.0 or above is required for this reconnect feature.
> -  Also, when DPDK vhost-user acts as the client, it will keep trying to
> reconnect to the server (QEMU) until it succeeds. This is useful in two cases:
> -
> -    * When QEMU is not started yet.
> -    * When QEMU restarts (for example due to a guest OS reboot).
