Maintaining the Mac address of a VM

Make the below changes to the config file of the VM which is generally with .vmx extension 

Remove the three lines that begin with the following from the configuration file:

ethernet[n].generatedAddress
ethernet[n].addressType
ethernet[n].generatedAddressOffset

In these options, [n] is the number of the virtual Ethernet adapter — for example ethernet0.

Add the following line to the configuration file:

ethernet[n].address = 00:50:56:XX:YY:ZZ (XX has to be hexadecimal number between 00h and 3Fh, and YY and ZZ must be valid hexadecimal numbers between 00h and FFh.   )
