Changing a NIC in a VMware VM from a dynamic MAC into a static MAC address

Posted by jpluimers on 2010/06/23

Sometimes you want to hava a NIC in a VMware VM to have a static MAC address in stead of a dynamically generated one.

This page explains what to change in the VMX configuration file.


ethernet0.addressType = "generated"
ethernet0.generatedAddress = "00:0c:29:40:7e:22"
ethernet0.generatedAddressOffset = "0"


ethernet0.addressType = "static"
ethernet0.address = "00:50:56:3e:86:29"

VMware also has a few docs on this for workstation and ESX installs and a KB article for both.

  1. VMWare allows you to put in a static mac in the 00:50:56:xx:xx:xx range because of the use of some good old MAC-based licensing servers.

    Beware! When you use VMWare Converter or upgrade your VM to hw-version 7, these VMX changes may get lost. Therefore, it is recommended to configure the VM using either VirtualCenter or VSphere client.
