73c0a148af qemu: support event_idx parameter for virtio disk and net devices
In some versions of qemu, both virtio-blk-pci and virtio-net-pci
devices can have an event_idx setting that determines some details of
event processing. When it is enabled, it "reduces the number of
interrupts and exits for the guest". qemu will automatically enable
this feature when it is available, but there may be cases where this
new feature could actually make performance worse (NB: no such case
has been found so far).

As a safety switch in case such a situation is encountered in the
field, this patch adds a new attribute "event_idx" to the <driver>
element of both disk and interface devices. event_idx can be set to
"on" (to force event_idx on in case qemu has it disabled by default)
or "off" (for force event_idx off). In the case that event_idx support
isn't present in qemu, the attribute is ignored (this on the advice of
the qemu developer).

   "don't mess with this!"

ce7244a014 Improve tokenizing of linkable terms
Currently only tabs and blanks are used for tokenizing the description,
which breaks when a term is at the end of a line or has () appended to
it.
1. Use also other white space characters such as new-lines and carriage
   return for splitting.
2. Remove some common non-word characters from the token before lookup.

447e4c466e Align table cells on top
When the description of an entry is too long and needs multiple lines,
all other table cells of the same row are currently vertically aligned
on center. Without row borders or different background colors for
alternating rows this is hard to read.

Change the style-sheet to align the table cells of a row on top.

ef79fb5b5f conf: add <listen> subelement to domain <graphics> element
Once it's plugged in, the <listen> element will be an optional
replacement for the "listen" attribute that graphics elements already
have. If the <listen> element is type='address', it will have an
attribute called 'address' which will contain an IP address or dns
name that the guest's display server should listen on. If, however,
type='network', the <listen> element should have an attribute called
'network' that will be set to the name of a network configuration to
get the IP address from.

* docs/schemas/domain.rng: updated to allow the <listen> element

* docs/formatdomain.html.in: document the <listen> element and its
  attributes.

* src/conf/domain_conf.[hc]:

  1) The domain parser, formatter, and data structure are modified to
     support 0 or more <listen> subelements to each <graphics>
     element. The old style "legacy" listen attribute is also still
     accepted, and will be stored internally just as if it were a
     separate <listen> element. On output (i.e. format), the address
     attribute of the first <listen> element of type 'address' will be
     duplicated in the legacy "listen" attribute of the <graphic>
     element.

  2) The "listenAddr" attribute has been removed from the unions in
     virDomainGRaphicsDef for graphics types vnc, rdp, and spice.
     This attribute is now in the <listen> subelement (aka
     virDomainGraphicsListenDef)

  3) Helper functions were written to provide simple access
     (both Get and Set) to the listen elements and their attributes.

* src/libvirt_private.syms: export the listen helper functions

* src/qemu/qemu_command.c, src/qemu/qemu_hotplug.c,
  src/qemu/qemu_migration.c, src/vbox/vbox_tmpl.c,
  src/vmx/vmx.c, src/xenxs/xen_sxpr.c, src/xenxs/xen_xm.c

  Modify all these files to use the listen helper functions rather
  than directly referencing the (now missing) listenAddr
  attribute. There can be multiple <listen> elements to a single
  <graphics>, but the drivers all currently only support one, so all
  replacements of direct access with a helper function indicate index
  "0".

* tests/* - only 3 of these are new files added explicitly to test the
  new <listen> element. All the others have been modified to reflect
  the fact that any legacy "listen" attributes passed in to the domain
  parse will be saved in a <listen> element (i.e. one of the
  virDomainGraphicsListenDefs), and during the domain format function,
  both the <listen> element as well as the legacy attributes will be
  output.

fe957f0a6f bandwidth: Integrate bandwidth into portgroups
Every DomainNetDef has a bandwidth, as does every portgroup.
Whenever a DomainNetDef of type NETWORK is about to be used, a call is
made to networkAllocateActualDevice(). This function chooses the "best"
bandwidth object and places it in the DomainActualNetDef.
From that point on, whenever some code needs to use the bandwidth data
for the interface, it's retrieved with virDomainNetGetActualBandwidth(),
which will always return the "best" info as determined in the
previous step.

Define new 'bandwidth' element with possible child element 'inbound'
and 'outbound' addressing incoming and outgoing traffic respectively:

<bandwidth>
  <inbound average='1000' peak='2000' burst='5120'/>
  <outbound average='500'/>
</bandwidth>

Leaving any element out means not to shape traffic in that
direction.
The units for average and peak (rate) are in kilobytes per second,
for burst (size) are just in kilobytes.
This element can be inserted into domain's 'interface' and
'network'.

40fd7073be conf: support abstracted interface info in network XML
The network XML is updated in the following ways:

1) The <forward> element can now contain a list of forward interfaces:

     <forward .... >
       <interface dev='eth10'/>
       <interface dev='eth11'/>
       <interface dev='eth12'/>
       <interface dev='eth13'/>
     </forward>

   The first of these takes the place of the dev attribute that is
   normally in <forward> - when defining a network you can specify
   either one, and on output both will be present. If you specify
   both on input, they must match.

2) In addition to forward modes of 'nat' and 'route', these new modes
   are supported:

     private, passthrough, vepa - when this network is referenced by a
     domain's interface, it will have the same effect as if the
     interface had been defined as type='direct', e.g.:

        <interface type='direct'>
          <source mode='${mode}' dev='${dev}>
          ...
        </interface>

     where ${mode} is one of the three new modes, and ${dev} is an interface
     selected from the list given in <forward>.

     bridge - if a <forward> dev (or multiple devs) is defined, and
     forward mode is 'bridge' this is just like the modes 'private',
     'passthrough', and 'vepa' above. If there is no forward dev
     specified but a bridge name is given (e.g. "<bridge
     name='br0'/>"), then guest interfaces using this network will use
     libvirt's "host bridge" mode, equivalent to this:

       <interface type='bridge'>
          <source bridge='${bridge-name}'/>
          ...
       </interface>

3) A network can have multiple <portgroup> elements, which may be
   selected by the guest interface definition (by adding
   "portgroup='${name}'" in the <source> element along with the
   network name). Currently a portgroup can only contain a
   virtportprofile, but the intent is that other configuration items
   may be put there int the future (e.g. bandwidth config). When
   building a guest's interface, if the <interface> XML itself has no
   virtportprofile, and if the requested network has a portgroup with
   a name matching the name given in the <interface> (or if one of the
   network's portgroups is marked with the "default='yes'" attribute),
   the virtportprofile from that portgroup will be used by the
   interface.

4) A network can have a virtportprofile defined at the top level,
   which will be used by a guest interface when connecting in one of
   the 'direct' modes if the guest interface XML itself hasn't
   specified any virtportprofile, and if there are also no matching
   portgroups on the network.

07f4136993 conf: support abstracted interface info in domain interface XML
the domain XML <interface> element is updated in the following ways:

1) <virtualportprofile> can be specified when source type='network'
(previously it was only valid for source type='direct')

2) A new attribute "portgroup" has been added to the <source>
element. When source type='network' (the only time portgroup is
recognized), extra configuration information will be taken from the
<portgroup> element of the given name in the network definition.

3) Each virDomainNetDef now also potentially has a
virDomainActualNetDef which is a private object (never
exported/imported via the public API, and not defined in the RNG) that
is used to maintain information about the physical device that was
actually used for a NetDef of type VIR_DOMAIN_NET_TYPE_NETWORK.

The virDomainActualNetDef will only be parsed/formatted if the
parse/format function is called with the
VIR_DOMAIN_XML_INTERNAL_ACTUAL_NET flag set (which is only needed when
saving/loading a running domain's state info to the stateDir).

a3d95b550b conf: put virtPortProfile struct / functions in a common location
virtPortProfiles are currently only used in the domain XML, but will
soon also be used in the network XML. To prepare for that change, this
patch moves the structure definition into util/network.h and the parse
and format functions into util/network.c (I decided that this was a
better choice than macvtap.h/c for something that needed to always be
available on all platforms).

e5adda7e6b website: Point main page links to libvirt driver pages
The "libvirt supports:" section on the main page of libvirt.org
contains a list of hypervisors with links that point to the sites of
the underlying virt technologies.  The entry for KVM points to
http://www.linux-kvm.org/, for example.  People coming to libvirt.org
for the first time are likely to know about those sites, and they're
probably interested in how libvirt manages those technologies.  This
patch points those links to the libvirt driver pages instead.  It also
consolidates KVM and QEMU as there is only one libvirt driver page for
them.  Finally, it adds a line about networking support.

v2: incorporate Eric's feedback adding project links to driver pages.

The sub-elements of <ip> had been placed at the same level of
indentation as ip itself, implying that they were really elements of
<network>. Within that, sub-elements of ip/dhcp were also at that same
level. These have been double-indented.

At the same time, I realized that the documentation for the new <dns>
element had been placed right in the middle of the description of the
sub-elements of <ip>. I moved it up out of the way.

9d4e2845d4 Network: Add support for DNS hosts definition to the network XML
This commit introduces names definition for the DNS hosts file using
the following syntax:

  <dns>
    <host ip="192.168.1.1">
      <name>alias1</name>
      <name>alias2</name>
    </host>
  </dns>

Some of the improvements and fixes were done by Laine Stump so
I'm putting him into the SOB clause again ;-)

5dd986dbd7 Add TXT record support for virtual DNS service
This commit introduces the <dns> element and <txt> record for the
virtual DNS network. The DNS TXT record can be defined using following
syntax in the network XML file:

  <dns>
    <txt name="example" value="example value" />
  </dns>

Also, the Relax-NG scheme has been altered to allow the texts without
spaces only for the name element and some nitpicks about memory
free'ing have been fixed by Laine so therefore I'm adding Laine to the
SOB clause ;-)

017abcbb1a qemu: domain I/O asynchronous handling
For virtio disks and interfaces, qemu allows users to enable or disable
ioeventfd feature. This means, qemu can execute domain code, while
another thread waits for I/O event. Basically, in some cases it is win,
in some loss. This feature is available via 'ioeventfd' attribute in disk
and interface <driver> element. It accepts 'on' and 'off'. Leaving this
attribute out defaults to hypervisor decision.
