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 v2.7 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). + +Test Case1: vhost-user/virtio-pmd pvp reconnect from vhost-user +=============================================================== +Flow: TG--> NIC --> Vhost --> Virtio --> Vhost--> NIC--> TG + +1.
