As you can see, there are some warnings, but they do not affect the creation of the cluster. You can click to view the report to check the cause of the warning. A warning is reported because the heartbeat line is not set in my environment. The heartbeat line is not required for creating a cluster on Windows Server 2012 R2. Select "create cluster with verified nodes now" and click "finish" to start cluster creation.

The cluster has been created. However, to achieve high availability of hyper-V virtual machines, two more operations are required: Adding cluster shared volumes and configuring High Availability of virtual machines.

A) add a shared cluster volume.

Open the Failover Cluster Manager, select the disk that you want to add as the cluster shared volume, and click "add to cluster shared volume" in the Action Blue column on the right"

650) This. width = 650; "Title =" clip_image038 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image038 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959257PsXg.jpg "Height =" 414 "/>

650) This. width = 650; "Title =" clip_image040 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image040 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959257PGPF.jpg "Height =" 414 "/>

After the shared volumes of the cluster are successfully added, a volume shortcut is generated in clusterstorage under the C disk of the host server servera and serverb, as shown in figure

650) This. width = 650; "Title =" clip_image042 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image042 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959258k9Tq.jpg "Height =" 172 "/>

B) Configure High Availability of virtual machines

Open the Failover Cluster Manager, right-click the role-configure the role

650) This. width = 650; "Title =" clip_image046 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image046 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959259CVzO.jpg "Height =" 416 "/>

Open the high availability wizard and click Next

650) This. width = 650; "Title =" clip_image048 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image048 "src =" http://img1.51cto.com/attachment/201407/21/212259_14059592597YJB.jpg "Height =" 431 "/>

In select role, select virtual machine, and click Next

650) This. width = 650; "Title =" clip_image050 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image050 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959260vjBM.jpg "Height =" 431 "/>

Select the virtual machine to be configured as highly available. I chose test and click Next.

650) This. width = 650; "Title =" clip_image052 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image052 "src =" http://img1.51cto.com/attachment/201407/21/212259_14059592602TeW.jpg "Height =" 430 "/>

Click Next

650) This. width = 650; "Title =" clip_image054 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image054 "src =" http://img1.51cto.com/attachment/201407/21/212259_14059592615d10.jpg "Height =" 435 "/>

The high availability configuration of the Test Virtual Machine is complete, but a warning is displayed. Click to view the report to check the cause.

650) This. width = 650; "Title =" clip_image056 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image056 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959261dUSl.jpg "Height =" 430 "/>

The warning can be found in the report because the test virtual machine is not stored, and you can move test to the storage. Next I will introduce how to move virtual machines to storage in a Failover cluster.

650) This. width = 650; "Title =" clip_image058 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image058 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959262xqay.jpg "Height =" 408 "/>

First, create a folder with the same name as the Test Virtual Machine in the storage to save all files related to the virtual machine.

650) This. width = 650; "Title =" clip_image060 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image060 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959262Hk5x.jpg "Height =" 241 "/>

Then, open the Failover Cluster Manager and right-click Test Virtual Machine ------- mobile ------- Virtual Machine Storage

650) This. width = 650; "Title =" clip_image062 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image062 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959263qPy3.jpg "Height =" 423 "/>

Select a folder named test with the same name as the virtual machine test, click test in the upper-right corner of the VM, hold down the left mouse button, and drag it directly to the right of the lower-right corner.

650) This. width = 650; "Title =" clip_image064 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image064 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959264pTKB.jpg "Height =" 314 "/>

After the Virtual Machine storage is moved, the virtual machine has the real-time migration (high availability) feature.

The following is a test of the real-time migration of the virtual machine:

A) before performing the migration, find a server to ping the virtual machine test. Note that the IP address of the Test Virtual Machine is 192.168.1.222, in the DOS window, Ping 192.168.1.222-t.

650) This. width = 650; "Title =" clip_image066 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image066 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959264so2f.jpg "Height =" 179 "/>

B) Open the Failover Cluster Manager and choose Test Virtual Machine-right-click-Move-real-time migration-best Node

650) This. width = 650; "Title =" clip_image068 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image068 "src =" http://img1.51cto.com/attachment/201407/21/212259_1405959265cp2i.jpg "Height =" 481 "/>

Real-time migration in progress

650) This. width = 650; "Title =" clip_image070 "style =" border-top: 0px; border-Right: 0px; Background-image: none; border-bottom: 0px; padding-top: 0px; padding-left: 0px; border-left: 0px; padding-Right: 0px; "Border =" 0 "alt =" clip_image070 "src =" http://img1.51cto.com/attachment/201407/21/212259_14059592657jbf.jpg "Height =" 291 "/>

After the migration is completed, observe the ping results. We can see that only two packages are lost during the migration. I use Simulated Storage. If the optical fiber is used to connect to the physical storage, may not even cause packet loss.
