Re: [libvirt] Associate a LUN as disk with WWNN/WWPN

I like the idea. It could be used for other things:
- QEMU usermode iSCSI backend, including storing iSCSI secrets outside
the domain XML. In this case, multiple domains will usually share the
pool and specify different volumes.
- SCSI controller passthrough: instead of defining the destination
inside the domain XML, just refer to a SCSI (or perhaps iSCSI) pool.
NPIV ends up being a special case.
However, for the case of controller passthrough, wouldn't you end up
basically with a separate pool for each domain? Especially for NPIV
where each domain will use a separate WWPN/WWNN? It's still an
advantage compared to duplicating the WWPN/WWNN once per LUN, but it may
be a bit complex to manage.
