machine is set up to create a new UUID every time it is moved. Power off the virtual
machine and begin using it as a template by copying the virtual machine files to other
locations.
If you intend to move the virtual machine numerous times, and want to keep the
same UUID each time the virtual machine moves, then select Always Keep and click
OK to continue powering on the virtual machine.
Note: If you want to change the Always Keep or Always Create setting, power off the
virtual machine and edit its configuration file (.vmx). Delete the line that contains
uuid.action = "create"
or
uuid.action = "keep"
Suspending and resuming a virtual machine does not trigger the process that
generates a UUID. Thus, the UUID in use at the time the virtual machine was
suspended remains in use when the virtual machine is resumed, even if it has been
copied or moved. However, the next time the virtual machine is rebooted, the
message appears, so you can choose to create a new UUID or keep the existing one.
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.
