    Using Signaling to Simplify Network Virtualization Provisioning
                   draft-kompella-nvo3-server2nve-00

Abstract

   This document proposes a "single-touch" approach for provisioning the
   networking parameters related to Virtual Machine creation, migration
   and termination on servers.  The idea is to provision the server,
   then have the server signal the requisite parameters to the relevant
   network device(s).  Such an approach reduces the workload on the
   provisioning system and simplifies the data model that the
   provisioning system needs to maintain.  Furthermore, it is more
   resilient to topology changes in server-network connectivity, for
   example, reconnecting a server to a different network port or switch.

1.  Introduction

   Creating a Virtual Machine (VM) on a server in a data center and
   making it operational involves several steps, among them:

   1.  gathering the CPU, network, storage, and appliance parameters
       required for the VM;

   2.  deciding which server, network, storage and appliance devices
       best match the VM requirements in the current state of the data
       center;

   3.  provisioning the server with the VM parameters;
