How to Enable VMI (Paravirtualization) in VMware ESX Virtual Machines

By | October 20, 2010

 

VMI, or the Virtual Machine Interface, is a clearly defined extensible specification for OS communication with the hypervisor. In theory Paravirtualization (where the guest kernel knows that it’s running on a hypervisor, not “real” hardware) is faster than pure hardware virtualization.

In full virtualization, a guest operating system runs unmodified on a hypervisor. However, improved performance and efficiency is achieved by having the guest operating system communicate with the hypervisor. By allowing the guest operating system to indicate its intent to the hypervisor, each can cooperate to obtain better performance when running in a virtual machine. This type of communication is referred to as paravirtualization.

Enable VMI in virtual machine,

1. Power Off virtual machine.

2. Right-click the virtual machine and select Edit Settings.

3. Click the Options table.

4. Under Settings, select Paravirtualization.

5. Select the Support VMI Paravirtualization checkbox.

6. Click OK.

7. Power on the virtual machine.

To enable the support the guest operating system need to support Paravirtualization technology.
