Rework the code to perform the various searches by parent, parent_wwnn/ parent_wwpn, parent_fabric_wwn, or vport capable in order to return the 'parent_host' number that is vHBA capable. The former virNodeDeviceGetParentHost is renamed to add the ByParent on it fixes an issue where if no parent was supplied in the XML to create the vHBA, then virNodeDeviceFindByName was called with a NULL second parameter which had bad results. The reworked code will make the various calls to fetch the NPIV host by the passed parameter options or if none are provided find a vport capable NPIV HBA to perform the create. If the call is from the delete path, then this option won't be allowed. Each of virNodeDeviceGetParentHostBy* functions is now static, so remove them external definitions. A secondary benefit of this is the test_driver now can make use of the new API to add some new tests to test the various creation options.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
