Overview

Introduction

The Managing Virtual Machine Networks module provides you with the instruction and server hardware to develop your hands on skills in the defined topics. This module includes the following exercises:

  • Configure Hyper-V Virtual Switches
  • Configure Network Isolation
  • Optimize Network Performance

Exam Objectives

The following exam objectives are covered in this lab:

  • Add and remove virtual network interface cards
  • Configure Hyper-V virtual switches
  • Optimize network performance
  • Configure synthetic and legacy virtual network adapters
  • Configure NIC teaming in VMs

Lab Duration

It will take approximately 1 hour to complete this lab.

Exercise 1 - Configure Hyper-V Virtual Switches

A virtual network switch is software-based switch that works just as a physical network switch. Ports are added or removed when virtual machines are connected to or disconnected from a virtual network.

Hyper-V Virtual Network Manager offers three types of virtual networks:

External virtual networks. Used to provide virtual machines with access to a physical network and communicate with externally located servers and clients.

Internal virtual networks. Use to allow network communication between virtual machines on the same virtualization server and between virtual machines and the management operating system.

Private virtual network. Used to allow network communication between virtual machines on the same virtualization server. A private virtual network is not bound to a physical network adapter. This type of network is used to create an isolated network environment.

In this exercise, you will create and configure Hyper-V virtual switches.

Exercise 2 - Configure Network Isolation

The network isolation feature on a Hyper-V Server enables you to work with multiple network segments that can isolate virtual machines and physical computers from one another. This allows you to work with an array of services on virtual machines without the risk of disrupting the services on another part of the network, say the live production network.

In this exercise, you will configure network isolation in virtual machines maintained by Hyper-V Server.

Exercise 3 - Optimize Network Performance

To enhance network performance between a virtual machine and the physical network, Windows Server Hyper-V supports Single Root Input-Output (SR-IOV) networking. SR-IOV is a standard to optimize the performance of a PCI Express device, such as a network interface card, with virtualization solutions, such as provided by Windows Hyper-V. The input-output performance of the virtual network adapter in guest virtual machines is greatly enhanced as it can keep up with the link speed of the physical network adapter in a Hyper-V host.
