Specifying a UUID for a Virtual Machine
In some circumstances you may want to assign a specific UUID to the virtual machine. To do this, you need to override the automatically generated UUID value. Power off the virtual machine and edit its configuration file (.vmx) to set the value of the UUID parameter. Use a text editor to edit the configuration file. The format for the line is:
uuid.bios = <uuidvalue>
The UUID value must be surrounded by quotation marks. A sample configuration line looks like:
uuid.bios = "00 11 22 33 44 55 66 77-88 99 aa bb cc dd ee ff"
After adding this line to the configuration file, power on the virtual machine. The new UUID is used when the virtual machine boots.
