[libvirt] [PATCH 00/11] Allow creation of vHBA by parent_wwnn/wwpn or fabric_name

[John Ferlan]

https://bugzilla.redhat.com/show_bug.cgi?id=1349696

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.


John Ferlan (11):
  nodedev: Fix crash in libvirtd on vHBA creation path
  nodedev: Create helpers to search for vport capable nodedevs
  nodedev: Add ability to find a vport capable vHBA
  nodedev: Add the ability to create vHBA by parent wwnn/wwpn or
    fabric_wwn
  conf: Add more fchost search fields for storage pool vHBA creation
  iscsi: Clean up createVport exit paths
  iscsi: Change order of checks in createVport
  iscsi: Converge more createVport checks
  util: Remove need for extra VIR_FREE's in virGetFCHostNameByWWN
  util: Introduce virGetFCHostNameByFabricWWN
  iscsi: Add parent wwnn/wwpn or fabric capability for createVport
