Lots of details in the bz, but essentially the problem is that providing a "parent" scsi_hostX value has drawbacks on reboots because what was scsi_hostX could turn into scsi_hostY on subsequent reboots.
So add the ability to use the parent wwnn/wwpn or fabric_wwn as 'search' criteria in order to create either non persistent vHBA's via nodedev or persistent vHBA's via storage pools.
NB: Documentation of this "process" is on the wiki:
http://wiki.libvirt.org/page/NPIV_in_libvirt
and would need to be adjusted once/if the changes are accepted.
