Makefiles are another easy file to enforce line limits.
Mostly straightforward; interesting tricks worth noting:
src/Makefile.am: $(confdir) was already defined, use it in more places
tests/Makefile.am: path_add and VG required some interesting compression

Use the virDomainSetMemoryStatsPeriodFlags() to pass a period defined by
usage of a new --period option in order to set the collection period for the
balloon driver. This may enable or disable the collection based on the value.
Add the --current, --live, & --config options to dommemstat.
When using logical pools, we had to trust the target->path provided.
This parameter, however, can be completely ommited and we can use
'/dev/<source.name>' safely and populate it to target.path.

Until now, the "host-model" cpu mode couldn't be influenced. This patch
allows to use the <feature> elements to either enable or disable
specific CPU flags. This can be used to force flags that can be emulated
even if the host CPU doesn't support them.
The existing 'chap' XML logic was never used - just defined. Rather than
try to insert a square peg into a round hole, blow it up and rewrite the
logic to follow the 'ceph' format.
Remove the former "chap.login" and "chap.passwd" fields and replace
with "chap.username" and "chap.secret" in _virStoragePoolAuthChap.
Adjust the virStoragePoolDefParseAuthChap() to process.
Change the rng file to describe the new layout
Update the formatstorage.html to describe the usage of the secret element
to mention that the secret type "iscsi" and "ceph" can be used
to storage pool too.
Update the formatsecret.html to include a reference to the storage pool
Update tests to handle the changes from 'login' and 'passwd' to 'username'
and '<secret>' format

On systems where git cannot access the outside world, a developer
can instead arrange to get a copy of gnulib at the right commit
via side channels (such as NFS share drives), set GNULIB_SRCDIR,
then use ./autogen.sh --no-git. In this setup, we will now
avoid direct use of git. Of course, this means no automatic
gnulib updates when libvirt.git updates its submodule, but it
is expected that any developer in such a situation is already
prepared to deal with the fallout.
* .gnulib: Update to latest, for bootstrap.
* bootstrap: Synchronize from gnulib.
* autogen.sh (no_git): Avoid git when requested.
* cfg.mk (_update_required): Skip automatic rerun of bootstrap if
we can't use git.
* docs/compiling.html.in: Document this setup.
* docs/hacking.html.in: Mention this.
* HACKING: Regenerate.

This patch introduces new element <idmap> for
user namespace. for example
<idmap>
<uid start='0' target='1000' count='10'/>
<gid start='0' target='1000' count='10'/>
</idmap>
this new element is used for setting proc files
/proc/<pid>/{uid_map,gid_map}.
This patch also supports multiple uid/gid elements
setting in XML configuration.
We don't support the semi configuation, user has to
configure uid and gid both.

Historically security issues in libvirt have been primarily
triaged & fixed by the Red Hat libvirt members & Red Hat
security team, who then usually notify other vendors via
appropriate channels. There have been a number of times
when vendors have not been properly notified ahead of
announcement. It has also disadvantaged community members
who have to backport fixes to releases for which there are
no current libvirt stable branches.
To address this, we want to make the libvirt security process
entirely community focused / driven. To this end I have setup
a new email address "libvirt-security@redhat.com" for end
users to report bugs which have (possible) security implications.
This email addr is backed by an invitation only, private
archive, mailing list. The intent is for the list membership
to comprise a subset of the libvirt core team, along with any
vendor security team engineers who wish to participate in a
responsible disclosure process for libvirt. Members of the
list will be responsible for analysing the problem to determine
if a security issue exists and then issue fixes for all current
official stable branches & git master.
I am proposing the following libvirt core team people as
members of the security team / list (all cc'd):
Daniel Berrange (Red Hat)
Eric Blake (Red Hat)
Jiri Denemar (Red Hat)
Daniel Veillard (Red Hat)
Jim Fehlig (SUSE)
Doug Goldstein (Gentoo)
Guido Günther (Debian)
We don't have anyone from Ubuntu on the libvirt core team.
Serge Hallyn is the most frequent submitter of patches from
Ubuntu in recent history, so I'd like to invite him to join.
Alternatively, Serge, feel free to suggest someone else to
represent Ubuntu's interests.
If any other vendors/distros have security people who are
responsible for dealing with libvirt security issues, and
want to join to get early disclosure of issues, they can
suggest people. Existing security team members will vet /
approve such requests to ensure they are genuine.
Anyone on the team / list will be **required** to honour any
embargo period agreed between members for non-public issues
that are reported. The aim will be to have a maximum 2 week
embargo period in the common case, extendable to 1 month if
there is sufficient justification made. If anyone feels they
are unable to follow such an embargo process for whatever
reason, please decline membership of the security list/team.
The patch which follows puts up some docs on the website
about all of this....
Document how to report security bugs and the process that
will be used for addressing them.

Somehow I put an example of a domain interface with a <vlan> element
into the network documentation.
This patch replaces that with an example of a network definition that
has a vlan element with trunk='yes', multiple tags, and even the new
nativeMode attribute. It also includes a <portgroup> that has a vlan
defined.
This patch adds functionality to allow libvirt to configure the
'native-tagged' and 'native-untagged' modes on openvswitch networks.

All APIs that take typed parameters are only using params address in
their entry point debug messages. With the new VIR_TYPED_PARAMS_DEBUG
macro, all functions can easily log all individual typed parameters
passed to them.
Add <features> and <compat> elements to volume target XML.
<compat> is a string which for qcow2 represents the QEMU version
it should be compatible with. Valid values are 0.10 and 1.1.
1.1 is implicit if the <features> element is present, otherwise
qemu-img default is used. 0.10 can be specified to explicitly
create older images after the qemu-img default changes.
<features> contains optional features, so far
<lazy_refcounts/> is available, which enables caching of reference
counters, improving performance for snapshots.
Add new CPU features for HyperV:
vapic for virtual APIC support
spinlocks for setting spinlock support

</hyperv>
</features>

This attribute is going to represent number of queues for
multique vhost network interface. This commit implements XML
extension part of the feature and add one test as well. For now,
we can only do xml2xml test as qemu command line generation code
is not adapted yet.
-vnc :5900,share=allow-exclusive
allows clients to ask for exclusive access which is
implemented by dropping other connections Connecting
multiple clients in parallel requires all clients asking
for a shared session (vncviewer: -shared switch)
-vnc :5900,share=force-shared
disables exclusive client access. Useful for shared
desktop sessions, where you don't want someone forgetting
specify -shared disconnect everybody else.
-vnc :5900,share=ignore
completely ignores the shared flag and allows everybody
connect unconditionally
QEMU might support more values for "-drive discard", so using Bi-state
values (on/off) for it doesn't make sense.
"on" maps to "unmap", "off" maps to "ignore":
<...>
@var{discard} is one of "ignore" (or "off") or "unmap" (or "on") and
controls whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
requests are ignored or passed to the filesystem. Some machine types
may not support discard requests.
</...>
The following XML configuration can be used to request all domain's
memory pages to be kept locked in host's memory (i.e., domain's memory
pages will not be swapped out):
<memoryBacking>
<locked/>

Change the build process & driver initialization so that the
VirtualBox driver is built into libvirtd, instead of libvirt.so
This change avoids the VirtualBox GPLv2-only license causing
compatibility problems with libvirt.so which is under the
GPLv2-or-later license.
NB this change prevents use of the VirtualBox driver on the
Windows platform, until such time as libvirtd can be made
to work there.

QEMU introduced "discard" option for drive since commit a9384aff53,
<...>
@var{discard} is one of "ignore" (or "off") or "unmap" (or "on") and
controls whether @dfn{discard} (also known as @dfn{trim} or @dfn{unmap})
requests are ignored or passed to the filesystem. Some machine types
may not support discard requests.
</...>
This patch exposes the support in libvirt.
QEMU supported "discard" for "-drive" since v1.5.0-rc0:
% git tag --contains a9384aff53
contains
v1.5.0-rc0
v1.5.0-rc1
So this only detects the capability bit using virQEMUCapsProbeQMPCommandLine.
