Yes. id = 0 means it is not the snapshot and isn't affected.

Well, from the 'collie vdi list', it seems that the internally created
VDI is also snapshot. It looks weird to me, because this new VDI is
writeable(I am not sure of it, but I can do 'dd' inside). So it is
better seen as a clone. Kazutaka, is this intentional? How about marking
this VDI as clone?
