[VNFD] Referencing VM images in the VNFD

[mbredel]

In the VDU section of the VNFD we reference a virtual machine image. Questions are:

• How can we reference a VM image uniquely? A UUID is hard to read/write for humans. A simple name might be ambiguous. In fact we could have the same VNFD referencing the same VM image, but the image might be different - resulting in a different VNF.

Are you referring to virtual_deployment_units: vm_image field in the VNFD ? Wouldnt it be the URL or URI ?

[mbredel]

Yes, that was the field I was referring to. The field could point to an URL - then we are fine. But if it points to an image that is in the package for example, than it becomes tricky.

I think this is related to our discussion in #61. Without the metadata, the image reference would need to be either unique, such that the service platform could just store it (and find it again), or the service platform would need to modify the VNFD.
