Practice exercises

The goal of this section is to provide you with hands-on practice with the following:

Preparing servers for shared nothing live migration
Preparing servers for Hyper-V Replica
Configuring virtual machine replication
Performing planned virtual machine replication failover
Performing shared nothing live migration
Managing storage migration
Exporting, importing, and cloning a virtual machine
Performing unplanned virtual machine replication failover

Unlike other chapters in this book, the practice exercises in this lesson require that you have two reasonably identical computers that will function as Hyper-V hosts. Unlike the other server roles that are addressed by the 70-412 exam, running Hyper-V in a supported configuration requires that you install the operating system on “bare metal.” It is possible with some virtualization solutions to trick Windows Server 2012 so that it detects that it is running directly on hardware when in fact it is running in a virtualized state. If you know how to configure a third-party virtualization solution to do this, you can build a lab for this chapter in this manner.

When selecting host computers for MEL-HV-1 and MEL-HV-2, ensure that they meet the following Hyper-V virtualization requirements:

1.4 GHz or faster x64 processor with hardware-assisted virtualization. Included with Intel Virtualization Technology (Intel VT) or AMD Virtualization (AMD-V) technology.
Hardware enforced Data Execution Prevention (DEP). On processors that use Intel architecture, this involves enabling the Intel XP (Execute Disable) bit or the AMD NX (No Execute) bit.

Figure 8-23 serves as a starting point to describe the environment created for this set of practice exercises.

FIGURE 8-23 The lab infrastructure

The Windows 8.1 Enterprise Edition computer running client Hyper-V and hosting virtual machines SYD-DC, MEL-DC, ADL-DC, and CBR-DC. The client Hyper-V virtual switch is configured with two virtual switches: a private switch and an external switch. Practice exercises in all other chapters of this book assume that SYD-DC, MEL-DC, ADL-DC, and CBR-DC are configured so that network adapters are matched to the private switch.
SYD-DC.contoso.com is a virtual machine running the evaluation version of Windows Server 2012 R2 and is configured as described in the introduction of this book. The main change is instead of being configured to use a private network on the Hyper-V host, the SYD-DC.contoso.com virtual machine network adapter is configured to use an external network. SYD-DC.contoso.com retains existing Internet Protocol (IP) address information.
MEL-HV-1 is running the evaluation version Windows Server 2012 R2 Standard Edition. MEL-HV-1 is deployed on computer hardware in a traditional bare metal configuration. MEL-HV1 is configured with the following IP address information and is joined to the contoso.com domain:
- IP Address: 10.10.10.51
- Subnet Mask: 255.0.0.0
- DNS Server Address: 10.10.10.10
MEL-HV-2 is running the evaluation version Windows Server 2012 Standard Edition. HEL-HV-2 is deployed on computer hardware in a traditional bare metal configuration. MEL-HV2 is configured with the following IP address information and is joined to the contoso.com domain:
- IP Address: 10.10.10.52
- Subnet Mask: 255.0.0.0
- DNS Server Address: 10.10.10.10
You might wish to enable Remote Desktop on MEL-HV-1 and MEL-HV-2 so that you can manage everything centrally from your workstation.
Copy the Windows Server 2012 R2 evaluation edition iso file to the folder c:\iso on MEL-HV-1.
