devnp-vdevpeer.so

io-pkt-* driver that provides the hypervisor host with a network interface to connect to a guest's virtio-net vdev.

Syntax:

io-pkt-v6-hc -d vdevpeer [peer=path,option[,option...]
	     [,peer=path,option,[,option ...] ...]]

Runs on:

QNX Neutrino

Options:

peer=path: Path to connection ID (coid) to communicate over
mac=XXXXXXXXXXXX: MAC address of this peer
name=peername: Prefix to the name of this peer; default is “vp”
bind=path: Path to the other node; equals the other peer node's peer option

Description:

The devnp-vdevpeer.so driver enables io-pkt-* networking manager running in the host to communicate with virtual network devices configured for guests. It can be used to facilitate peer-to-peer communications between the hypervisor host and guests, between guests, and between guests and the outside world.

To use the devnp-vdevpeer.so driver to set up peer-to-peer communication between nodes in the hypervisor system and with the outside world, you need to:

in the hypervisor host, start io-pkt-*, specifying the devnp-vdevpeer.so driver (e.g., io-pkt-v4-hc -d vdevpeer)
in the devnp-vdevpeer.so driver options, configure the node in the hypervisor host: the connection path, the MAC address, a name for the node, and the path to the node in the guest
in the qvm configuration file for the VM that will host the guest, configure the virtio-net vdev (see “vdev virtio-net” in the “Configuration” chapter).

For more information about setting up peer-to-peer communications, see “Networking” in the “Using Your Hypervisor System” chapter.
