You can change the power-on connection setting, the MAC address, and the network connection for the virtual network adapter configuration for a virtual machine.

 

Prerequisites

 

Required privilege: Network.Assign network on a network if you are changing the network the virtual

machine connects to.

Procedure

 

  1. Select a virtual machine.
  2. In the VM Hardware panel, click Edit Settings.
  3. Click Virtual Hardware.
  4. Click the triangle next to the network adapter to expand the network adapter options.
  5. (Optional) Specify how the MAC address is assigned.
    1. Select Automatic to automatically assign a MAC address.
    2. Select Manual to manually enter the MAC address you want.

Type of Network Adapters and their usage scenarios

 

NIC Type

Description

E1000

Emulated version of the Intel 82545EM Gigabit Ethernet NIC, with drivers available in most newer guest operating systems, including Windows XP and later and Linux versions 2.4.19 and later.

Flexible

Identifies itself as a Vlance adapter when a virtual machine boots, but initializes itself and functions as either a Vlance or a VMXNET adapter, depending on which driver initializes it. With VMware Tools installed, the VMXNET driver changes the Vlance adapter to the higher performance VMXNET adapter.

Vlance

Emulated version of the AMD 79C970 PCnet32 LANCE NIC, an older 10 Mbps NIC with drivers available in most 32bit guest operating systems except Windows Vista and later.

VMXNET

Optimized for performance in a virtual machine and has no physical counterpart. Because operating system vendors do not provide built-in drivers for this card, you must install VMware Tools to have a driver for the VMXNET network adapter available.

VMXNET2 (Enchanced)

Based on the VMXNET adapter but provides high-performance features

such as jumbo frames and hardware offloads.

VMXNET3

VMXNET 3 offers all the features available in VMXNET 2 and adds new features, such as multiqueue support (also known as Receive Side Scaling in Windows), IPv6 offloads, and MSI/MSI-X interrupt delivery. VMXNET 3 is not related to VMXNET or VMXNET 2.
