I already tried that, with no benefit.

I spent some more time on that and here what I found :

* 1 *
When trying to import a VM by cloning it and using a suffix (whatever 
suffix), I get NO error in log (neither on the manager, nor in the 
nodes), but I'm stuck with the yellow border around the suffix field, 
and no way to validate my choice.

* 2 *
I succeed in importing directly the VM by NOT checking the "Clone All 
VMs" box, and by checking the "Collapse All snapshots" box. Indeed, I 
found in engine.log an error about snapshots, an INSERT was tried into 
the database with a broken constrain key and a 
'000000000000000000.0000.blah.blah.blah' snapshot reference.
Checking this box allowed a correct import of the VM.

Conclusion :
- Point 1 : I consider it would be nice to inform the user about what's 
wrong, at least in the log files
- Point 2 : When not checking to collapse snapshot box, the import is 
failing with an error speaking about a duplicated MAC address.
This is wrong.

Thank you to Shahar, Itamar and Alex who answered.
