VMware: Change MAC address in .VMX with “Virtual Mac Tool”
After installing a new VMXNET3 network card my HP MAC based license server didn’t function anymore. To change the MAC address in the VMX file I used a very nice tool, called: Virtual MAC Tool created by Richard Garsthagen.
How to:
- Turn off your VM;
- Open Virtual MAC Tool;
- Connect your ESX host or VC;
– Select the VM and vNIC/Network you want to change the MAC address
- In my case MAC: 00:0C:29:46:CF:1E and click “Set”
After clicking “Set” you see current MAC status and status Reconfigure VM Tasks Completed Successfully. My license server is working again.
Awesome tool! 
Will this tool work with ESXi 4.1 Embedded.
I have tried another method, remove vm from inventory, edit vmx file.
Changed ethernet0.addressType=”vpx” to ethernet0.addressType=”static”
Changed ethernet0.generatedaddress = “00:50:56:xx:xx:xx” to ethernet0.address = “00:50:56:xx:xx:xx”
Found also that 4.1 does not recognize vmx file if you add ethernet0.checkMACaddress= “false” to the vmx
Any assistance would be highly appreciated.
thanks awesome tool worked on a 2000 box that had tts software bound to mac address =D
