Set the EVC mode of a virtual machine to ensure its seamless migration across clusters, vCenter Server systems, and datacenters that have different processors.
The virtual machine must be powered off before you can enable, disable, or change its EVC mode.
To verify the EVC mode of virtual machines, see Determine the EVC Mode of a Virtual Machine
- In the vSphere Client, navigate to the virtual machine.
- 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.
- Click Edit and select whether to enable or 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.
This option is visible only if you have customized the EVC mode of the virtual machine through the API calls.
- If you want to enable EVC, choose a baseline CPU feature set from the VMware EVC Mode drop-down menu.
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.
- Click OK.
