You can override the generated UUID and assign a specific UUID to a virtual machine.

Power off the virtual machine.


Open the virtual machine configuration (.vmx) file in a text editor.


Search for the line that contains uuid.bios.

The format of the line is uuid.bios = "uuid_value". The UUID is a 128-bit integer. The 16 bytes are separated by spaces, except for a dash between the eighth and ninth hexadecimal pairs.

For example: uuid.bios = "00 11 22 33 44 55 66 77-88 99 aa bb cc dd ee ff"


Replace the existing UUID value with the specific UUID value.


Power on the virtual machine.

The virtual machine uses new UUID is used when it reboots.
