Prerequisites
Verify that the hosts you intend to add to the cluster meet the requirements listed in EVC Requirements
for Hosts.
Procedure
1 Right-click a data center in the inventory and select New Cluster.
2 Type a name for the cluster.
3 Expand EVC and select a baseline CPU feature set from the EVC mode drop-down menu.
Select a CPU vendor and EVC mode appropriate for the hosts that you intend to add to the cluster.
4 (Optional) Enable DRS.
5 (Optional) Enable vSphere HA.
6 Click OK.
7 Select a host to move into the cluster.
If the host feature set is greater than the EVC mode that you enabled for the EVC cluster, power off
all the virtual machines on the host, or use vMotion to migrate them to another host.
8 Move the host into the cluster.
You can power on the virtual machines that are on the host, or migrate virtual machines into the
cluster with vMotion. The virtual machines must meet CPU compatibility requirements for the EVC
mode of the cluster.
You can now use vMotion to migrate virtual machines between different hosts in the cluster without
encountering CPU incompatibility issues.
Enable EVC on an Existing Cluster
Enable EVC on an existing cluster to ensure vMotion CPU compatibility between the hosts in the cluster.
