ESXi can determine whether a virtual machine should use hardware support for virtualization. ESXi makes this determination based on the processor type and the virtual machine. Overriding the automatic selection can provide better performance for some use cases.

Procedure

  1. Right-click a virtual machine in the inventory and select Edit Settings.
  2. On the Virtual Hardware tab, expand CPU, and select an instruction set from the CPU/MMU Virtualization drop-down menu.
  3. Click OK.
