Change the EVC Mode for a Cluster
Configure EVC to ensure that virtual machine migrations between hosts in the cluster do not fail because
of CPU feature incompatibilities.
Several EVC approaches are available to ensure CPU compatibility:
n
If all the hosts in a cluster are compatible with a newer EVC mode, you can change the EVC mode of
an existing EVC cluster.
n
You can enable EVC for a cluster that does not have EVC enabled.
n
You can raise the EVC mode to expose more CPU features.
n
You can lower the EVC mode to hide CPU features and increase compatibility.
Prerequisites
n
Verify that all hosts in the cluster have supported CPUs for the EVC mode you want to enable. See
http://kb.vmware.com/kb/1003212 for a list of supported CPUs.
n
Verify that all hosts in the cluster are connected and registered on vCenter Server. The cluster cannot
contain a disconnected host.
n
Virtual machines must be in the following power states, depending on whether you raise or lower the
EVC mode.
EVC Mode Virtual Machine Power Action
Raise the EVC mode to a CPU
baseline with more features.
Running virtual machines can remain powered on. New EVC mode features are not
available to the virtual machines until they are powered off and powered back on again. A
full power cycling is required. Rebooting the guest operating system or suspending and
resuming the virtual machine is not sufficient.
Lower the EVC mode to a CPU
baseline with fewer features.
Power off virtual machines if they are powered on and running at a higher EVC Mode
than the one you intend to enable.
To verify the EVC mode for virtual machines, see Determine the EVC Mode of a Virtual Machine.
Procedure
1 Select a cluster in the inventory.
2 Click the Configure tab.
3 Select VMware EVC, and click Edit.
4 Select whether to enable or disable EVC.
Option Description
Disable EVC The EVC feature is disabled. CPU compatibility is not enforced for the hosts in
this cluster.
Enable EVC for AMD Hosts The EVC feature is enabled for AMD hosts.
Enable EVC for Intel Hosts The EVC feature is enabled for Intel hosts.
