Exactly - if a OVF import would not create a new UUID then VirtualBox 
would e.g. refuse to import the same OVF file twice. VirtualBox uses the 
VM UUID to distinguish VMs (we don't require the VM name to be unique, 
of couse it's a good idea to keep them unique for practical reasons)

Can you explain a little more why you need to be able to check the 
identity, or how you/the used software checks for identity? There might 
be possibilities, but without context it's impossible to guess what 
might be interesting for you.
