Specifying a UUID for a Virtual Machine
Note: VMware Tools may need to be removed from the virtual machine prior changing the UUID to prevent the UUID from reverting.
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 (.vmx) file 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 = ""
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 you add this line to the configuration file, power on the virtual machine. The new UUID is used when the virtual machine boots.
