AFAIU libvirt needs a way to:

- Associate a virtual adapter WWN with a VM (in the VM xml)
- Learn to start a virtual adapter when the VM is started, and destroy the
   adapter when the VM is stopped.
- Possibly a way to associate a WWN with a scsi pool, to start / stop a
   virtual adapter with the pool.

But afer thinking more, I'd think it might be not good idea:

As far as I could understand, the requirement of the BZ wants
a way to create/migrate a guest with NPIV. I'm goint to talk
create first,and migration then.

The desire to assocaite WWNN/WWPN with a VM is just one part of a more
general need to expand libvirt's SCSI support. Paulo started a design
thread on the subject a month or so back which sort of converged into


Yes, I read this thread before, but it looks to me Paolo was talking
about LUN, scsi host, and vHBA passthrough. It's a bit different
with what I'm trying to resolve (There is no passthrough here, but
about how to design a good workflow between virt-manager / Boxes
and libvirt for using (creating and migration ) a FC LUN as a normal
disk). The useful thing in the discussion of the thread may be
define the (v)HBA as a controller though.

Or I misunderstood something?
