VM Guest LAN Support

Introduction

The Virtual Machine (VM) Control Program (CP) allows you to create and simulate a LAN formed by virtual Network Interface Cards (NIC). You can define a LAN or a VSWITCH to represent the network. You can define a virtual NIC to represent an adapter in a guest I/O configuration. You can couple a virtual NIC to a VM LAN or VSWITCH to make it part of a network.
