Add new fields to the fchost structure to allow creation of a vHBA via
the storage pool when a parent_wwnn/parent_wwpn or parent_fabric_wwn is
supplied in the storage pool XML.
https://bugzilla.redhat.com/show_bug.cgi?id=1349696
When creating a vHBA, the process is to feed XML to nodeDeviceCreateXML
that lists the <parent> scsi_hostX to use to create the vHBA. However,
between reboots, it's possible that the <parent> changes its scsi_hostX
to scsi_hostY and saved XML to perform the creation will either fail or
create a vHBA using the wrong parent.
So add the ability to provide "wwnn" and "wwpn" or "fabric_wwn" to
the <parent> instead of a name of the scsi_hostN that is the parent.
The allowed XML will thus be:
<parent>scsi_host3</parent> (current)
or
<parent wwnn='$WWNN' wwpn='$WWPN'/>
or
<parent fabric_wwn='$WWNN'/>
Using the wwnn/wwpn or fabric_wwn ensures the same 'scsi_hostN' is
selected between hardware reconfigs or host reboots. The fabric_wwn
Using the wwnn/wwpn pair will provide the most specific search option,
while fabric_wwn will at least ensure usage of the same SAN, but maybe
not the same scsi_hostN.
This patch will add the new fields to the nodedev.rng for input purposes
only since the input XML is essentially thrown away, no need to Format
the values since they'd already be printed as part of the scsi_host
data block.
New API virNodeDeviceGetParentHostByWWNs will take the parent "wwnn" and
"wwpn" in order to search the list of devices for matching capability
data fields wwnn and wwpn.
New API virNodeDeviceGetParentHostByFabricWWN will take the parent "fabric_wwn"
in order to search the list of devices for matching capability data field
fabric_wwn.
When generating the plain text version of the contributor
guidelines we add a ludicrous amount of vertical whitespace
in some spots. Tweak the XSLT stylesheet and regenerate the
now much better looking file.
When updating the source file in commit bd4f4d1686, I forgot
that we also store the generated plain text version in git and
didn't regenerate it.
I also missed one spot that required an additional <p> tag, so
fix both mistakes in one go.
Some of the <li> elements in the "General tips for contributing
patches" section were missing the corresponding inner <p> element,
so they ended up all lumped together.
Although the virStorageBackendUpdateVolTargetInfo will update the
target.physical value, there is no way to provide that information
via the virStorageGetVolInfo API since it only returns the capacity
and allocation of a volume. So as described in commit id '0282ca45',
it should be possible to generate an output only <physical> value
for that purpose.
This patch generates the <physical> value in the volume XML output
for the sole purpose of being able to view/see the value to allow
someone to parse the XML in order to obtain the value.
Update the documentation to describe the output only nature.

In the website reorg we accidentally lost all links to the nice
reformatted news.html file. Add a link on the front page, and
also extend the download page table so that it includes links
to API docs and news files for each module (where available)

The github.com/rgbkrk/libvirt-go bindings were the most complete
bindings historically, but their API coverage stops at 1.2.4,
with exception of a couple of newer APIs.
The new bindings at http://libvirt.org/git/?p=libvirt-go.git;a=log
how have (almost[1]) 100% API coverage all the way to 2.5.0. They also
expose the APIs in a way that allows for much stronger go type
checking by the compiler, and expose typed parameters as explicit
structs. Finally the bindings are able to conditionally compile against
any libvirt version 1.2.0 -> 2.5.0 without use of go build tags.
Change the docs to point to these new bindings, since they'll be
a better bet for users long term.
[1] virEvent & virStream callbacks are still TODO to be fixed
real soon.

Similarly to localOnly DNS domain, localPtr attribute can be used to
tell the DNS server not to forward reverse lookups for unknown IPs which

Documents in formatdomain.html that when migrating a guest
defined with the host-passthrough CPU model from a machine that
is running on a newer CPU model than the destination machine's
CPU model, it is very likely that the guest will crash upon
arrival.

Seems commit id '0257d06b' forgot to include formatstorage when updating
the docs to describe allowing zfs as a pool type and to furthermore note
that the pool's target path element will be generated rather than read.
Similarly commit id 'efab27afb' neglected to indicate that the target path
for a logical pool will now be generated by libvirt.

When changing one of the src/libvirt-*.c files to alter the docs, the
adjusted files weren't being built. Added them into APIBUILD_STAMP and
then added that to the html/index.html rule which is used for the
$(apihtml_generated) generated rule.
Also, for clean we can remove the html/*.html files
So far the NSS module looks up only hostnames as provided by
guests themselves. However, there are some cases where this is
not enough: e.g. when there's a fresh new guest being installed
(with some generic hostname) say from a live ISO image; or some
(older) systems don't advertise their hostname in DHCP
transactions at all.
In cases like that it would be helpful if we translate domain
name as seen by libvirt too so that users can:
# virsh start $dom && ssh $dom
In order to achieve that new libvirt-guest module is introduced,
while older libvirt module maintains its current behaviour (that
is translating guest provided names into IP addresses).
