+1 about Jay option.

BTW, as nova and glance all allow same name for instance or image, So name
seems not need to be unique, it is OK I think.



Thanks

   IMHO, making the Bay/Baymodel name as a MUST will bring more flexibility
   to end user as Magnum also support operating Bay/Baymodel via names and
   the name might be more meaningful to end users.

   Perhaps we can borrow some iead from nova, the concept in magnum can be
   mapped to nova as following:

   1) instance => bay
   2) flavor => baymodel

   So I think that a solution might be as following:
   1) Make name as a MUST for both bay/baymodel
   2) Update magnum client to use following style for bay-create and
   baymodel-create: DO NOT add "--name" option

  You should decide whether name would be unique -- either globally or
  within a tenant.

  Note that Nova's instance names (the display_name model field) are *not*
  unique, neither globally nor within a tenant. I personally believe this
  was a mistake.

  The decision affects your data model and constraints.
Yes, my thinking is to enable Magnum has same behavior with nova. The name
can be managed by the end user and the end user can specify the name as
they want, it is end user's responsibility to make sure there are no
duplicate names. Actually, I think that the name do not need to be unique
but UUID.

  Best,
