Procedure
1 In the vSphere Client, right-click on a data center and click New Cluster.
2 Enter a name for the cluster and select cluster features, then click Next.
Cluster features such as vSphere DRS and vSphere HA are fully compatible with EVC. You can enable
these features when you create the cluster. For information on specific cluster options, see the vSphere
Client online Help.
3 Select the CPU vendor and EVC mode appropriate for the hosts you intend to add to the cluster and
click Next.
4 Select the Swapfile Policy and click Next.
5 Review the selected options for the cluster and click Finish to create the cluster.
6 Select a host from the inventory to move into the cluster.
7 If the host feature set is greater than the EVC mode that you have enabled for the EVC cluster, ensure
that the cluster has no powered-on virtual machines.
n
Power off all the virtual machines on the host.
n
Migrate the host’s virtual machines to another host using vMotion.
8 Move the host into the cluster.
You can power on the virtual machines on the host, or migrate virtual machines into the cluster with
vMotion, if the virtual machines meet CPU compatibility requirements for the cluster’s EVC mode.
Virtual machines running on hosts with more features than the EVC mode must be powered off before
migration into the cluster.
9 Repeat Step 7 and Step 8 for each additional host that you want to move into the cluster.
Enable EVC on an Existing Cluster
Enable EVC on an existing cluster to help ensure vMotion compatibility between the hosts in the cluster.
Prerequisites
n
You must be connected to a vCenter Server system with the vSphere Client.
n
Before you enable EVC on an existing cluster, ensure that the hosts in the cluster meet the requirements
listed in the vCenter Server and Host Management publication.
Procedure
1 In the vSphere Client, select the cluster for which you want to enable EVC.
2 If virtual machines are running on hosts that have feature sets greater than the EVC mode you intend to
enable, ensure that the cluster has no powered-on virtual machines.
n
Power off all the virtual machines on the hosts with feature sets greater than the EVC mode
n
Migrate the cluster’s virtual machines to another host using vMotion.
Because these virtual machines are running with more features than the EVC mode you intend to
set, power off the virtual machines to migrate them back into the cluster after enabling EVC.
3 Ensure that the cluster contains hosts with CPUs from only one vendor, either Intel or AMD.
4 Edit the cluster settings and enable EVC.
Select the CPU vendor and feature set appropriate for the hosts in the cluster.
