Purpose

This article provides steps to change the virtual machine monitor mode.

Note: You must consult the VMware documentation and choose an appropriate virtual machine monitor mode depending on the type of hardware, guest operating system, and the version of ESX/ESXi that you use.

Resolution

To change the virtual machine monitor mode:

Note: The virtual machine must be powered off while performing this procedure.

Log in to the VMware vSphere Client.

In the virtual machine inventory, right-click the virtual machine and click Edit Settings. The Virtual Machine Properties dialog appears.

Click the Options tab.

Set the CPU/MMU Virtualization option under Advanced with one of these options:

Automatic

Use software for instruction set and MMU virtualization

Use Intel VT-X/AMD-V for instruction set virtualization and software for MMU virtualization.

Use Intel VT-X/AMD-V for instruction set virtualization and Intel EPT/AMD RVI for MMU virtualization.

Click OK to save your changes.

Power on the virtual machine.

Available and Selected Modes
Not all systems are capable of all modes, the mode actually used depends both on the configuration and the features provided by the system CPUs. To identify the modes available and the mode actually used by virtual machine, review the virtual machine's vmware.log file located at the virtual machine folder on the datastore.

For example:

datetime| vmx| MONITOR MODE: allowed modes : BT HV HWMMU
datetime| vmx| MONITOR MODE: user requested modes : BT HV HWMMU
datetime| vmx| MONITOR MODE: guestOS preferred modes: BT HWMMU HV
datetime| vmx| MONITOR MODE: filtered list : BT HWMMU HV

Where:

allowed modes – Refers to the mode that the underlying hardware is capable of.

user requested modes – Refers to the setting defined in the virtual machine configuration.

guestOS preferred modes – Refers to the default values for the selected guest operating system.

filtered list – Refers to the actual monitor modes acceptable for use by the Hypervisor, with the left-most mode being utilized.

To change the virtual machine monitor mode using the vSphere Web Client:

In the Inventory, right-click the virtual machine and click Edit Settings.

Click the Virtual Hardware tab.

Expand the CPU caret.

Select the required option from the CPU/MMU Virtualization dropdown.

Click OK to save your changes.

Power ON the virtual machine.
