If we expose this information, which is one byte in every PCI config
file, we let all mgmt apps know whether the device itself is an endpoint
or not so it's easier for them to decide whether such device can be
passed through into a VM (endpoint) or not (*-bridge).

The docs claims the cache attribute of the disk <driver>
element supports 'default' as one of its permissible values,
but such configuration fails virt-xml-validate. Add 'default'
as one of the cache attribute choices in domaincommon.rng.
- Add line-height:150% spacing for all text. This makes text lines far
less cramped, and seems closer visually to what wikipedia uses.
- Remove bottom and top margin from lists: entries seemed needlessly
spread out.
- Reduce sublist indentation a bit
- Add a bottom border after headings: IMO this greatly helps in break
up the vertical flow of a big page of text. Doesn't look great on the
front page, but helps a lot on dense pages like formatdomain
- change font-family to just 'sans-serif' rather than hardcode a few
font families. this means we abide the user's browser font setting,
and makes us consistent with other sites like en.wikipedia.org
- raise font-size to 90%. this is what en.wikipedia.org uses.
With these two tweaks, libvirt.org text renders the same as
en.wikipedia.org with fedora firefox out of the box config. Previously
the font on libvirt.org was very small and difficult to read.
Extend the chardev source XML so that there is a new optional
<log/> element, which is applicable to all character device
backend types. For example, to log output of a TCP backed
serial port
<serial type='tcp'>
<source mode='connect' host='127.0.0.1' service='9999'/>
<protocol type='raw'/>
<log file='/var/log/libvirt/qemu/demo-serial0.log' append='on'/>
<target port='0'/>
</serial>
Not all hypervisors will support use of logfiles.

This attribute is used to extend secondary PCI bar and expose it to the
guest as 64bit memory. It works like this: attribute vram is there to
set size of secondary PCI bar and guest sees it as 32bit memory,
attribute vram64 can extend this secondary PCI bar. If both attributes
are used, guest sees two memory bars, both address the same memory, with
the difference that the 32bit bar can address only the first part of the
whole memory.

Imagine you have partially installed libvirt, or maybe you're
just running 'make uninstall' from a different version than 'make
install' has been ran. One way or another, we are doing plain
'rm' instead of 'rm -f' and thus not trying hard enough when
uninstalling. In the rest of our code we stick with -f switch. Do
that for docs too.

Recent changes to the handling of GIC version, specifically commit
2a7b11eafb, have clearly defined what values are acceptable for the
version attribute of the <gic> element. Update the documentation
accordingly.
This change allows to use "host" as a GIC version in the domain XML.
Since we'll need to update the virGICVersion enumeration to support
new GIC versions anyway, it makes sense to be a bit more strict in
the schema as well and reject values that are not in the enumeration.
When generating docs in a VPATH build we get a failure to
create a file due to the 'internals' subdir not existing:
Generating internals/locking.html.tmp
/bin/sh: line 3: internals/locking.html.tmp: No such file or directory
rm: cannot remove ‘internals/locking.html.tmp’: No such file or directory
Makefile:2229: recipe for target 'internals/locking.html.tmp' failed
make: *** [internals/locking.html.tmp] Error 1
For some reason, make has decided to run the target
%.html.tmp: %.html.in site.xsl page.xsl sitemap.html.in $(acl_generated)
instead of the target
internals/%.html.tmp: internals/%.html.in subsite.xsl page.xsl sitemap.html.in
Removing '$(acl_generated)' from the first target, inexplicably
causes make to now run the correct target for the internals/
files.
Rather than figure this out, lets just combine the two targets
into one.

Add a new storage pool source device attribute 'part_separator=[yes|no]'
in order to allow a 'disk' storage pool using a device mapper multipath
device to not add the "p" partition separator to the generated device
name when libvirt_parthelper is run.
This will allow libvirt to find device mapper multipath devices which were
configured in /etc/multipath.conf to use 'user_friendly_names' or custom
'alias' names for the LUN.
So after da176bf6b7 and friend we have switched to $(wildcard
some/path/*.xml) instead of enumerating the files explicitly.
This is nice, however it makes distcheck build from VPATH fail.
The reason is that it's is not obvious to what does the wildcard
refer to: srcdir or builddir?

Excessive memory balloon inflation can cause invocation of OOM-killer,
when Linux is under severe memory pressure. QEMU memballoon device
has a feature to release some memory at the last moment before some
process will be get killed by OOM-killer.
Introduce a new optional balloon device attribute 'autodeflate' to
enable or disable this feature.
If no port number was provided for a storage pool libvirt defaults to
port 6789; however, librbd/librados already default to 6789 when no port
number is provided.
In the future Ceph will switch to a new port for the Ceph monitors since
port 6789 is already assigned to a different application by IANA.
Port 6789 is assigned to SMC-HTTPS and Ceph now has port 3300 assigned as
the 'Ceph monitor' port.
In this case it is the best solution to not hardcode any port number into
libvirt and let librados handle the connection.
Only if a user specifies a different port number we pass it down to librados,
otherwise we leave it blank.

The documentation (and comment in libvirtd.conf) says that the text in
a log filter is compared to the "source file name", and gives the
example of "util/json", but this is not correct (at least not since
commit 2835c1e, possibly earlier). It is instead compared to the
string given in the VIR_LOG_INIT() macro invocation at the top of each
source file, which is always "similar to but not the same as" the
source file name (in the example above, the proper name is
"util.json", while the file name is "util/virjson.c"). This patch
corrects the misstatement in both the documentation and in
libvirtd.conf.
Currently, there is no possibility for user to specify desired behaviour of
output to file - truncate or append. This patch adds an ability to explicitly
specify that user wants to preserve file's content on reopen.

Using more than 4TiB of memory per NUMA node would not be possible to
express in the XML without violating the schema. Not that such boxes
would be common, but we should use a longer type at this point.
The pattern is not necessary since libvirt redefines the type already in
basictypes.rng with the same pattern.
To be used by the family of virtio input devices:
<input type='mouse' bus='virtio'/>
<input type='tablet' bus='virtio'/>
<input type='keyboard' bus='virtio'/>

As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.
qemu 2.5 provides virtio video device. It can be used with -device
virtio-vga for primary devices, or -device virtio-gpu for non-vga
devices. However, only the primary device (VGA) is supported with this
patch.

'model' attribute was added to a panic device but only one panic
device is allowed. This patch changes panic device presence
from 'optional' to 'zeroOrMore'.
Libvirt already has two types of panic devices - pvpanic and pSeries firmware.
This patch introduces the 'model' attribute and a new type of panic device.
'isa' model is for ISA pvpanic device.
'pseries' model is a default value for pSeries guests.
'hyperv' model is the new type. It's used for Hyper-V crash.
Schema and docs are updated for the new attribute.
Report the maximum possible number of VFs for an SRIOV PF, like this:
<capability type='virtual_functions' maxCount='7'>
...
</capability>
I've just discovered that the virtual_functions and physical_functions
capabilities are not supported in the virNodeDeviceParse functions,
only in virNodeDeviceFormat (I suppose because they are only reported,
not set from XML). This should probably be remedied, but is less
immediately useful than the current patch.
Adjust the config code so that it does not enforce that target memory
node is specified. To avoid breakage, adjust the qemu memory hotplug
config checker to disallow such config for now.
