Many times when we move or copy a guest we need to keep the same UUID. As 
an example we have a VM that is running Centos 4 that we need upgraded to 
Centos 6.2. How we have done this in the past:

Build new VM
Install fresh Centos 6.2
Copy over the application
Shutdown the first VM
Shutdown the 2nd VM and change UUID to match first
Fire up 2nd VM if everything works kill delete 1st VM

We run into all sorts of other situations when we make copies as backups 
and need to go to one of the backups. We never need to run a two VMs with 
the same UUID, but often have a box where we need to change the UUID to 
match what an old box was using.
