Generating a new MAC address in VmWare GSX


I accidentally told VmWare not to generate a new id for a copied virtual machine. When I try to start both the oliginal and the copy the network traffic doesn’t work since both of the machines have the same MAC adress.

Since the address is generated from the identifier it will generate the same MAC each time.


Erase the following lines in .vmx file for the virtual machine.

uuid.location = “56 4d ef 90 5e ea 44 ce-4b 98 58 85 8d 6c d0 5f”
uuid.bios = “56 4d 2b 7b d8 44 e0 91-3c 4c 3e fc a6 a2 d2 e0”
ethernet0.generatedAddress = “00:0c:29:a2:d2:e0”
ethernet0.generatedAddressOffset = “0”
