To begin with the vMotion example scenario, prepare an EVC-enabled virtual environment for the hosts that you are configuring for vMotion. vSphere environments are typically organized into datacenters and clusters. Using vSphere EVC clusters reduces the risk of incompatible host CPUs that might prevent vMotion migrations.

This scenario instructs you to use a cluster for your vMotion environment. You can configure vMotion on hosts that are not in a cluster. Add your hosts to a cluster in order to use cluster-specific features such as vSphere EVC, vSphere DRS, vSphere HA, and vSphere distributed switches.

1

Connect to the vCenter Server system My vCenter Server 5.1 by using the vSphere Web Client.

2

Right-click the vCenter Server object and select New Datacenter.

3

Type My vMotion Datacenter and click OK.

4

Navigate to the My vMotion Datacenter object.

5

Right-click the datacenter, and select New Cluster.

6

Type My EVC Cluster in the Name text box.

7

Keep the Turn ON option deselected for both DRS and vSphere HA.

8

Enable EVC for the cluster to maximize vMotion compatibility.

EVC presents only the CPU instruction set of the least capable processor to guest operating systems. You cannot enable EVC on clusters that contain both hosts with AMD processors and hosts with Intel processors.

You can create a cluster without a special license, but you must have a license to enable a cluster for vSphere DRS or vSphere HA.

9

Click OK.

Add the hosts ESXi-A and ESXi-B to the cluster My EVC Cluster.
