Simple Step : Configuring Hyper-V Replicas in Windows Server 2012 R2

January 11, 2015

Hyper-V Replica. This new Windows Server 2012 feature enables you to replicate a virtual machine to another host or into the cloud, instead of moving the virtual machine, and to synchronize all virtual machine changes from the primary host to the host that holds the replica.

In some cases, you might want to have a spare copy of one virtual machine that you can run if the original virtual machine fails. By implementing high availability, you have one instance of a virtual machine. High availability does not prevent corruption of software that is running inside the virtual machine. One way to address the issue of corruption is to manually copy the virtual machine periodically. You also can back up the virtual machine and its storage. Although this solution achieves the desired result, it is resource intensive and time consuming. In addition, because
backups are performed periodically, you never have the exact same copy as the running virtual machine.

To complete this simple demo, make sure that you meet the requirement in your Test Lab Environment.

Make sure that you have 2 Physical machine to complete this simple demo, which is Host1 & Host2.

In Host1, verify that you have Domain Controller Server (in my setup, i have domain Server in Hyper-V Host1.)

Verify also all Physical Host connected & join domain to DC1 server.

1 – On the Host1 machine, open Hyper-V Manager, right click Host1 and click Hyper-V Settings…

1

2 – In Hyper-V Settings, click Replication Configuration, then click Enable this computer as a Replica server…

** In the Authentication and ports section, select Use Kerberos (HTTP).

** In the Authorization and storage section, point to E:\OSI-VM-Replica\ folder then click OK….

2

3 – In the Settings interface, click OK…

3

4 – Next, open Windows Firewall and Enable Rule for Hyper-V Replica HTTP Listener (TCP-In)…

4

5 – Repeat steps 1 through 4 on Host2 Machine…

6 – On the Host1 Machine, in the Hyper-V Manager, right-click OSI-Svr-Core VM and then click Enable Replication, then click Next…

6

7 – On the Specify Replica Server interface, browse to OSI-Host2 machine then click OK…

7

8 – On the Specify Replica Server interface, click next…

8

9 – On the Specify Connection Parameters interface, review the settings, and ensure that Use Kerberos authentication (HTTP) is selected, and then click Next…

9

10 – On the Choose Replication VHDs interface, ensure that VM is selected, and then click Next…

10

11 – On the Configure Replication Frequency interface, select 30 seconds from drop-down list box, and then click Next…

11

12 – On the Configure Additional Recovery Points interface, select Maintain only the latest recovery point, and then click Next…

12

13 – On the Choose Initial Replication Method interface, click Send initial copy over the network, select Start replication immediately, and then click Next…

13

14 – On the Completing the Enable Replication Wizard interface, click Finish…

14

15 – Wait few minutes for the replication to finish…

** You can monitor the progress of the initial replication in the Status column in the Hyper-V Manager console…

15

16 – To validate the replication, right-click VM, select Replication, and then click View Replication Health…

16

17 – Review content of the interface that appears, and verify that there are no errors…

That’s all for now..

As at this point, i have completed my MCSA 2012 R2 certification step by step…
