NPIV based deploys attempted to put the client vFC adapters on to the
fabric by creating the WWPNs ahead of time and mapping them to the
management partition. This created several issues and led to poor
performance.
There were issues around migration:
- Querying for a host could leave a stale adapter on the mgmt partition
There were issues with speed:
- Deploys could take over 120 seconds
- Migrations had additional delays
There were issues with some standard operations:
- Attaching a volume on a powered off VM required logging in the WWPNs
Subsequent analysis in Cinder showed that only some Cinder drivers had
this requirement. Many could work without this. Given the challenges
the code is removing the need to log in the WWPNs on the mgmt partition.
This resolves all of the above issues.
While it does limit some of the Cinder drivers when paired with NPIV,
ongoing work will be done to meet with the Cinder driver owners to see
if the requirements in their drivers can be relaxed.
For those that can not, the vSCSI Cinder Volume attach is also an option
and should provide the use cases that they need.

This change set provides a significant update to the nova-powervm
drivers dev-ref.
Rebases the documentation to reflect the development that has been done
over the last several months. Updates the readme to reflect the
execution that has completed.
Removes the fake_driver that is not useful.

Following the compute driver standards, the driver options should
be placed in their own configuration group. This change set
introduces the 'powervm' group.
Also, removed the reference to configuration credentials in the
README.rst file.

In preparation for stackforge proposal, updating the README.rst file to
include an updated set of information. Mostly tied to the new pypowervm
python library.
Also updates the API properties to remove references to the current
location of the API server. Makes the wording more generic.

1) Proper indent of continuation lines in bullet list item
2) Need to escape underscore at the end of "powervm_" so it's not
interpreted as a backlink.
3) Continuation lines for hyperlinks aren't possible in RST. In cases
where the link makes the line "too long", it's okay to break the
line-length rule. See the Dependencies section of the following
(approved) blueprint for precedent:
