Enable EVC on an existing cluster to help ensure vMotion compatibility between the hosts in the cluster.

Before you begin

Before you enable EVC on an existing cluster, ensure that the hosts in the cluster meet the requirements listed in EVC Requirements for Hosts.

Procedure

  1. Select the cluster in the inventory.
  2. Ensure that the cluster has no powered-on virtual machines.
    • Power off all the virtual machines on the hosts with feature sets greater than the EVC mode

    • 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. Click the Manage tab, select VMware EVC and click Edit.
  5. Enable EVC for the CPU vendor and feature set appropriate for the hosts in the cluster, and click OK.
  6. If you powered off or migrated virtual machines out of the cluster, power on the virtual machines in the cluster, or migrate virtual machines into the cluster.

    Power off virtual machines running with a larger feature set than the EVC mode that you enabled for the cluster before you move them back into the cluster.
