    This replicates the metadata field found in the domain configuration

I can't think of any good reason to do either of those, and having the
examples there will just lead to unusable patch emails from people who
can't be bothered to read the entire page.

This reverts commit 93135abf.

This feature was accidentally pushed in the feature freeze.

This reverts commit fe6a7789.

This feature was accidentally pushed in the feature freeze.

This is place as a sub-element of <source>, where other aspects of the
host-side connection to the network device are located (network or
bridge name, udp listen port, etc). It's a bit odd that the interface
we're configuring with this info is itself named in <target dev='x'/>,
but that ship sailed long ago:

    <interface type='ethernet'>
      <mac address='00:16:3e:0f:ef:8a'/>
      <source>
        <ip address='192.168.122.12' family='ipv4'
            prefix='24' peer='192.168.122.1'/>
        <ip address='192.168.122.13' family='ipv4' prefix='24'/>
        <route family='ipv4' address='0.0.0.0'
               gateway='192.168.122.1'/>
        <route family='ipv4' address='192.168.124.0' prefix='24'
               gateway='192.168.124.1'/>
      </source>
    </interface>

In practice, this will likely only be useful for type='ethernet', so
its presence in any other type of interface is currently forbidden in
the generic device Validate function (but it's been put into the
general population of virDomainNetDef rather than the
ethernet-specific union member so that 1) we can more easily add the
capability to other types, and 2) we can retain the info when set to
an invalid interface type all the way through to validation and report
a proper error, rather than just ignoring it (which is currently what
happens for many other type-specific settings).

(NB: The already-existing configuration of IP info for the guest-side
of interfaces is in subelements directly under <interface>, and the
name of the guest-side interface (when configurable) is in <guest
dev='x'/>).

The peer attribute is used to set the property of the same name in the
interface IP info:

  <interface type='ethernet'>
    ...
    <ip family='ipv4' address='192.168.122.5'
        prefix='32' peer='192.168.122.6'/>
    ...
  </interface>

Note that this element is used to set the IP information on the
*guest* side interface, not the host side interface - that will be
supported in an upcoming patch.

All the same information was already there, just in slightly different
places in the virDomainNetDef.

a.k.a. <hostdev mode='capabilities' type='net'>.

This replaces the existing nips, ips, nroutes, and routes with a
single virNetDevIPInfo, and simplifies the code by calling that
object's parse/format/clear functions instead of open coding.

There are currently two places in the domain where this combination is
used, and there is about to be another. This patch puts them together
for brevity and uniformity.

As with the newly-renamed virNetDevIPAddr and virNetDevIPRoute
objects, the new virNetDevIPInfo object will need to be accessed by a
utility function that calls low level Netlink functions (so we don't
want it to be in the conf directory) and will be called from multiple
hypervisor drivers (so it can't be in any hypervisor directory); the
most appropriate place is thus once again the util directory.

The parse and format functions are in conf/domain_conf.c because only
the domain XML (i.e. *not* the network XML) has this exact combination
of IP addresses plus routes. Note that virDomainNetIPInfoFormat() will
end up being the only caller to virDomainNetRoutesFormat() and
virDomainNetIPsFormat(), so it will just subsume those functions in a
later patch, but we can't do that until they are no longer called.

(It would have been nice to include the interface name within the
virNetDevIPInfo object (with a slight name change), but that can't
be done cleanly, because in each case the interface name is provided
in a different place in the XML relative to the routes and IP
addresses, so putting it in this object would actually make the code
more confused rather than simpler).

When support for <interface type='ethernet'> was added in commit
9a4b705f back in 2010, it erroneously looked at <source dev='blah'/>
for a user-specified guest-side interface name. This was never
documented though. (that attribute already existed at the time in the
data.ethernet union member of virDomainNetDef, but apparently had no
practical use - it was only used as a storage place for a NetDef's
bridge name during qemuDomainXMLToNative(), but even then that was
never used for anything).

When support for similar guest-side device naming was added to the lxc
driver several years later, it was put in a new subelement <guest
dev='blah'/>.

In the intervening years, since there was no validation that
ethernet.dev was NULL in the other drivers that didn't actually use
it, innocent souls who were adding other features assuming they needed
to account for non-NULL ethernet.dev when really they didn't, so
little bits of the usual pointless cargo-cult code showed up.

This patch not only switches the openvz driver to use the documented
<guest dev='blah'/> notation for naming the guest-side device (just in
case anyone is still using the openvz driver), and logs an error if
anyone tries to set <source dev='blah'/> for a type='ethernet'
interface, it also removes the cargo-cult uses of ethernet.dev and
<source dev='blah'/>, and eliminates if from the RNG and from
virDomainNetDef.

NB: I decided on this course of action after mentioning the
inconsistency here:

  https://www.redhat.com/archives/libvir-list/2016-May/msg02038.html

and getting encouragement do eliminate it in a later IRC discussion
with danpb.

This patch enables admin socket creation in daemon's code, bumps the library
version in libvirt_admin_public.syms, and performs all necessary modifications
to our makefiles so that admin API can finally be included in the tarball,
and eventually become part of an rpm package (a patch later in this series).

Many moons ago, commit id '8d7800a5' adjusted the format of the output
to add a space on the HEADER and the DATA... the docs weren't updated to
reflect that... This makes that adjustment.

In the case of chassisNr (used to set chassis_nr of a pci-bridge
controller), 0 is reserved for / used by the pci[e]-root bus. In the
base of busNr, a value of 0 would mean that the root bus had no places
available to plug in new buses, including the pxb itself (the
documentation I wrote for pxb even noted the limit of busNr as 1.254).

NB: oddly, the "chassis" attribute, which is used for pcie-root-port
and pcie-switch-downstream-port *can* be set to 0, since it's the
combination of {chassis, slot} that needs to be unique, not chassis by
itself (and slot 0 of pcie-root is reserved, while pcie-*-port can use
*only* slot 0).

There was no documentation at all for the XML part. I added at least
some. The 2.0.0 introduction date is deliberate as the parser for the
XML is broken.

The schema file was missing entries for 'mbml' and 'mbmt'.

This allows us to produce releases that are roughly a third in
size, have no limitation on path length, and are still readable
by all supported platforms.

Commit 67f2b727 removed the path restrictions for rng backend,
along with the documentation of the restriction.

Restore the documentation for users still using older libvirt.

This new listen type is currently supported only by spice graphics.
It's introduced to make it easier and clearer specify to not listen
anywhere in order to start a guest with OpenGL support.

The old way to do this was set spice graphics autoport='no' and don't
specify any ports.  The new way is to use <listen type='none'/>.  In
order to be able to migrate to old libvirt the migratable XML will be
generated without the listen element and with autoport='no'.  Also the
old configuration will be automatically converted to the this listen
type.

VNC graphics already supports sockets but only via 'socket' attribute.
This patch coverts that attribute into listen type 'socket'.

For backward compatibility we need to handle listen type 'socket' and 'socket'
attribute properly to support old XMLs and new XMLs.  If both are provided they
have to match, if only one of them is provided we need to be able to parse that
configuration too.

To not break migration back to old libvirt if the socket is provided by user we
need to generate migratable XML without the listen element and use only 'socket'
attribute.

* docs/news.html.in: update with 1.3.5 data

In 38df47c9 I've tried to prepare our apibuild.py script for
change made in 0628f349 (1U << 31). What I've done in the
former commit was to replace \d+U in parsed tokens with \d.
Problem was, my regular expression there was not quite right as
it also translated VIR_123U_VAL into VIR_123_VAL.
Signed-off-by: NMichal Privoznik <mprivozn@redhat.com>

The apibuild script is a terrifying beast that parses some source
files of ours and produces an XML representation of them. When it
comes to parsing enums we have in some header files, it tries to
be clever and detect a value that an enum member has (or if it is
an alias for a different member). Whilst doing that it has to
deal with values we give to the members in many formats. At some
places we just pass the value in decimal:

    VIR_DOMAIN_BLOCK_JOB_TYPE_PULL = 1,

in other places, we use the aliasing:

    VIR_CONNECT_GET_ALL_DOMAINS_STATS_ACTIVE = VIR_CONNECT_LIST_DOMAINS_ACTIVE,

and in other places bitwise shifts are used:

    VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS = 1 << 31, /* enforce requested stats */

The script tries to parse all of these resulting in the following
tokens: "1", "VIR_CONNECT_LIST_DOMAINS_ACTIVE", "1<<31"; Then, the
script tries to turn these into integers using python's eval()
function. This function succeeds on the first and the last
tokens. But, if we were to modify the last example so that it's
of the following form:

    VIR_CONNECT_GET_ALL_DOMAINS_STATS_ENFORCE_STATS = 1U << 31, /* enforce requested stats */

the token representing enum's member value will then be "1U<<31".
So our parsing is good. Unfortunately, python is not aware of the
difference between signed and unsigned C types, therefore eval()
fails over this token and the parser falls back thinking it's an
alias to another enum member. Well it's not.

The solution is to transform [0-9]U into [0-9] as for our
purposes here it's the same thing.

Hand-entering indexes for 20 PCI controllers is not as tedious as
manually determining and entering their PCI addresses, but it's still
annoying, and the algorithm for determining the proper index is
incredibly simple (in all cases except one) - just pick the lowest
unused index.

The one exception is USB2 controllers because multiple controllers in
the same group have the same index. For these we look to see if 1) the
most recently added USB controller is also a USB2 controller, and 2)
the group *that* controller belongs to doesn't yet have a controller
of the exact model we're just now adding - if both are true, the new
controller gets the same index, but in all other cases we just assign
the lowest unused index.

With this patch in place and combined with the automatic PCI address
assignment, we can define a PCIe switch with several ports like this:

  <controller type='pci' model='pcie-root-port'/>
  <controller type='pci' model='pcie-switch-upstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  <controller type='pci' model='pcie-switch-downstream-port'/>
  ...

These will each get a unique index, and PCI addresses that connect
them together appropriately with no pesky numbers required.

Add a new element to <domain> XML:
<os>
  <acpi>
    <table type="slic">/path/to/acpi/table/file</table>
  </acpi>
</os>

table blob.

Prior to this, <address type='pci'/> wasn't allowed when parsing
(domain+bus+slot+function needed to be a "valid" PCI address, meaning
that at least one of domain/bus/slot had to be non-0), the RNG
required bus to be specified, and if type was set to PCI when
formatting, domain+bus+slot+function would always be output.

This makes all the address attributes optional during parse and RNG
validation, and suppresses domain+bus+slot+function if domain+bus+slot
are all 0 (NB: if d+b+s are all 0, any value for function is
nonsensical as that will never happen in the real world, and after
the next patch we will always assign a real working address to any
empty PCI address before it is ever output to anywhere).

Note that explicitly setting all attributes to 0 is equivalent to
setting none of them, which is okay, since 0000:00:00 is reserved in
any PCI bus setup, and can't be used anyway.
