What you want is the ability to copy the VM configuration, not to change the UUID. The point of a UUID is that it is a Universally Unique ID, hence there should be only 1 such in the universe. Instead of suggesting a solution, it is better to explain the problem. Having the ability to clone the configuration of a VM would be a lot more useful (e.g. it can be done multiple times and wouldn't be limited to a single VM). > > We run into all sorts of other situations when we make copies as > backups > and need to go to one of the backups.
