2 Under the Configure tab, select VMware EVC.
The pane shows details about the EVC mode of the virtual machine and CPUID details.
Important For newly created virtual machines, the EVC mode that shows in the VMware EVC pane
is disabled.
For powered-off virtual machines, the VMware EVC pane always shows the EVC status defined at
the virtual machine level.
For powered-on virtual machines with per-VM EVC enabled, the VMware EVC pane shows the EVC
status defined at the virtual machine level.
For powered-on virtual machines with per-VM EVC disabled, the VMware EVC pane shows the EVC
mode that the virtual machine inherits from its parent EVC cluster or host.
3 Click Edit and select whether to enable or disable EVC.
Option Description
Disable EVC The EVC feature is disabled for the virtual machine. When you power on the
virtual machine, it inherits the feature set of its parent EVC cluster or host.
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.
Custom This option is visible only if you have customized the EVC mode of the virtual
machine through the API calls.
4 If you want to enable EVC, choose a baseline CPU feature set from the VMware EVC Mode drop-
down menu.
Important If the virtual machine is in an EVC cluster and the per-VM EVC mode exceeds the
cluster-based EVC mode, the virtual machine will fail to power on. The baseline CPU feature set for
the virtual machine should not contain more CPU features than the baseline CPU feature set of the
cluster.
5 Click OK.
Determine the EVC Mode of a Virtual Machine
The EVC mode of a virtual machine determines the CPU features that a host must have in order for the
virtual machine to power on and migrate. The EVC mode of a virtual machine is determined when the
virtual machine is powered on. In vSphere 6.7, the EVC mode of a virtual machine is independent from
the EVC mode that you configure for the cluster in which the virtual machine runs.
The EVC mode of a virtual machine is determined when the virtual machine is powered on. At power-on,
the virtual machine also determines the EVC mode of the cluster in which it is running. If the EVC mode
of a running virtual machine or the entire EVC cluster is raised, the virtual machine does not change its
EVC mode until it is powered off and powered on again. This means that the virtual machine does not use
any CPU features exposed by the new EVC mode until the virtual machine is powered off and powered
on again.
