This cleanups the documentation, reformat some of the paragraphs to use
<p> instead of </br> and rewrites the listen part to be more extendable.

According to MDN[1], 'margin-left' and similar CSS properties,
including 'margin-right', cannot be applied to the '::first-line'
pseudo-element, so this rule will never have any effect and can
be safely removed.

This patch adds new xml element, and so we can have the option of

While we have a wiki page describing the feature [1] since the
feature is distributed in our .tar.gz we ought to document it. So
I went ahead, copied the wiki page and reformatted so it fits our
docs coding style.

- remove top padding for h1. this means page titles sit flush with the top
of the side bar (like 'The virtualization API' on the front page)
- up the top padding for the remaining sections. makes it visually easier
to tell adjacent header sections apart, especially in dense wiki pages
- use two different spacing levels for h2-h4 and h5-h6,
gives pages some more visual flexibility
- use a slightly lower bottom padding... this makes top padding stick out
more which makes it visually easier to differentiate between adjacent
header sections
In order to follow recent comments which indicate support for specific
feature bits are supported by a specific QEMU version add the version
from whence the relaxed, vapic, and spinlocks support was added.
This patch adds support for "vpindex", "runtime", "synic",
"stimer", and "vendor_id" features available in qemu 2.5+.
- When Hyper-V "vpindex" is on, guest can use MSR HV_X64_MSR_VP_INDEX
to get virtual processor ID.
- Hyper-V "runtime" enlightement feature allows to use MSR
HV_X64_MSR_VP_RUNTIME to get the time the virtual processor consumes
running guest code, as well as the time the hypervisor spends running
code on behalf of that guest.
- Hyper-V "synic" stands for Synthetic Interrupt Controller, which is
lapic extension controlled via MSRs.
- Hyper-V "stimer" switches on Hyper-V SynIC timers MSR's support.
Guest can setup and use fired by host events (SynIC interrupt and
appropriate timer expiration message) as guest clock events
- Hyper-V "reset" allows guest to reset VM.
- Hyper-V "vendor_id" exposes hypervisor vendor id to guest.

When reading in an XML definition for a SCSI target device, the name
property of struct scsi_target refers to the @target element.
Let's fix this obvious typo and also extend the XML schema to provide
validation.

Most hypervisors use Hardware Assisted Paging by default and don't
require specifying the feature in domain conf. But some hypervisors
support disabling HAP on a per-domain basis. To enable HAP by default
yet provide a knob to disable it, extend the <hap> feature with a
'state=on|off' attribute, similar to <pvspinlock> and <vmport> features.
In the absence of <hap>, the hypervisor default (on) is used. <hap>
without the state attribute would be the same as <hap state='on'/> for
backwards compatibility. And of course <hap state='off'/> disables hap.

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.
