virtnetdevmidonet.c adds the way to bind and unbind the ports by
calling into the Midonet Host Agent control command line (installed
with the midolman package).

Delete .po files which contain zero translated strings. Refresh
the .pot file and pull down latest translations from Zanata.
When refreshing the libvirt.pot, it can be pushed to zanata
and .po files resynchonized using
# cd po
# rm libvirt.pot
# make libvirt.pot
# zanata-cli push
# zanata-cli pull
Note there is no need for 'make update-po', as long as you do
a zanata push, immediately followed by zanata pull, as the
Zanata server will ensure the .po files downloaded match the
just pushed .pot file.
Note at time of writing, it is strongly recommended to only
use the zanata Java client binary (zanata-cli), and not the
python client binary (zanata). This is because the moderately
large size of the libvirt pot file is causing errors when the
python client tries to push, which have been known to result
in the loss of all translations on the server, as well as also
preventing uploading of .po files themselves :-(
For a while now there are two places that gather information about NUMA
related guest configuration. While the XML can't be changed we can at
least store the data in one place in the definition.
Rename the numatune_conf.[ch] files to numa_conf as later patches will
move the rest of the definitions from the cpu definition to this one.
The virDBusMethodCall method has a DBusError as one of its
parameters. If the caller wants to pass a non-NULL value
for this, it immediately makes the calling code require
DBus at build time. This has led to breakage of non-DBus
builds several times. It is desirable that only the virdbus.c
file should need WITH_DBUS conditionals, so we must ideally
remove the DBusError parameter from the method.
We can't simply raise a libvirt error, since the whole point
of this parameter is to give the callers a way to check if
the error is one they want to ignore, without having the logs
polluted with an error message. So, we add a virErrorPtr
parameter which the caller can then either ignore or raise
using the new virReportErrorObject method.
This new method is distinct from virSetError in that it
ensures the logging hooks are run.

Moving code for parsing and formatting network routes to
networkcommon_conf helps reusing those routes for domains. The route
definition has been hidden to help reducing the number of unnecessary
checks in the format function.
systemd-machined introduced a new method CreateMachineWithNetwork
that obsoletes CreateMachine. It expects to be given a list of
VETH/TAP device indexes for the host side device(s) associated
with a container/machine.
This falls back to the old CreateMachine method when the new
one is not supported.
Introduce a parser/formatter for the xl config format. Since the
deprecation of xm/xend, the VM config file format has diverged as
new features are added to libxl. This patch adds support for parsing
and formating the xl config format. It supports the existing xm config
format, plus adds support for spice graphics and xl disk config syntax.
Disk config is specified a bit differently in xl as compared to xm. In
xl, disk config consists of comma-separated positional parameters and
keyword/value pairs separated by commas. Positional parameters are
specified as follows
target, format, vdev, access
Supported keys for key=value options are
devtype, backendtype
The positional paramters can also be specified in key/value form. For
example the following xl disk config are equivalent
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
See $xen_sources/docs/misc/xl-disk-configuration.txt for more details.
xl disk config is parsed with the help of xlu_disk_parse() from
libxlutil, libxl's utility library. Although the library exists
in all Xen versions supported by the libxl virt driver, only
recently has the corresponding header file been included. A check
for the header is done in configure.ac. If not found, xlu_disk_parse()
is declared externally.

Introduce a Xen xl parser
This parser allows for users to convert the new xl disk format and
spice graphics config to libvirt xml format and vice versa. Regarding
the spice graphics config, the code is pretty much straight forward.
For the disk {formating, parsing}, this parser takes care of the new
xl format which include positional parameters and key/value parameters.
In xl format disk config a <diskspec> consists of parameters separated by
commas. If the parameters do not contain an '=' they are automatically
assigned to certain options following the order below
target, format, vdev, access
The above are the only mandatory parameters in the <diskspec> but there
are many more disk config options. These options can be specified as
key=value pairs. This takes care of the rest of the options such as
devtype, backend, backendtype, script, direct-io-safe,
The positional paramters can also be specified in key/value form
for example
/dev/vg/guest-volume,,hda
/dev/vg/guest-volume,raw,hda,rw
format=raw, vdev=hda, access=rw, target=/dev/vg/guest-volume
are interpleted to one config.
In xm format, the above diskspec would be written as
phy:/dev/vg/guest-volume,hda,w
The disk parser is based on the same parser used successfully by
the Xen project for several years now. Ian Jackson authored the
scanner, which is used by this commit with mimimal changes. Only
the PREFIX option is changed, to produce function and file names
more consistent with libvirt's convention.

If detect_scsi_host_caps reports errors but keeps libvirtd going on
startup, the user is misled by the error messages. Transforming them
into warning still shows the problems, but indicates this is not fatal.
We use typedef IMedium IHardDisk to make IHardDisk hierachy from
IMedium (Actually it did on vbox 2.2 and 3.0's C++ API).
So when calling
VBOX_MEDIUM_FUNC_ARG*(IHardDisk, func, args)
we can directly replace it to
gVBoxAPI.UIMedium.func(IHardDisk, args)
When dealing with this two types, we get some rules from it's
hierachy relationship.
When using IHardDisk and IMedium as input, we can't transfer a
IMedium to IHardDisk. Like:
gVBoxAPI.UIHardDisk.func(IHardDisk *hardDisk, args)
Here, we can't put a *IMedium as a argument.
When using IHardDisk and IMedium as output, we can't transfer a
IHardDisk to IMedium. Like:
gVBoxAPI.UIMachine.GetMedium(IMedium **out)
Here, we can't put a **IHardDisk as a argument. If this case
do happen, we either change the API to GetHardDisk or write a
new one.
This allows to implement libvirt functions that use streams, such as
virDoaminScreenshot, without the need to store the downloaded data in
a temporary file first. The stream driver directly interacts with
libcurl to send and receive data.
The driver uses the libcurl multi interface that allows to do a transfer
in multiple curl_multi_perform() calls. The easy interface would do the
whole transfer in a single curl_easy_perform() call. This doesn't work
with the libvirt stream API that is driven by multiple calls to the
virStreamSend() and virStreamRecv() functions.
The curl_multi_wait() function is used to do blocking operations. But it
was added in libcurl 7.28.0. For older versions it is emulated using the
socket callback of the multi interface.
The current driver only supports blocking operations. There is already
some code in place for non-blocking mode but it is not complete.
This patch rewrites two public APIs. They are vboxNetworkUndefine
and vboxNetworkDestroy. They use the same core function
vboxNetworkUndefineDestroy. I merged it in one patch.
Add files parallels_sdk.c and parallels_sdk.h for code
which works with SDK, so libvirt's code will not mix with
dealing with parallels SDK.
To use Parallels SDK you must first call PrlApi_InitEx function,
and then you will be able to connect to a server with
PrlSrv_LoginLocalEx function. When you've done you must call
PrlApi_Deinit. So let's call PrlApi_InitEx on first .connectOpen,
count number of connections and deinitialize, when this counter
becomes zero.

Spawning the pkcheck program every time a permission check is

There are now two places in libvirt which use polkit. Currently
they use pkexec, which is set to be replaced by direct DBus API
calls. Add a common API which they will both be able to use for
this purpose.
No tests are added at this time, since the impl will be gutted
in favour of a DBus API call shortly.

XM and XL config are very similar. Disks are specified differently
in XL, but the old XM disk config is still supported by XL. XL also
supports new config like spice that was never supported by XM.
This patch moves all the common parsing and formatting functions to
the new file xen_common.c and adapts the XM parser/formatter accordingly.
This restructuring paves way for introducing an XL parser/formatter in
the future.

Implement ZFS storage backend driver. Currently supported
only on FreeBSD because of ZFS limitations on Linux.
Features supported:
- pool-start, pool-stop
- pool-info
- vol-list
- vol-create / vol-delete
Pool definition looks like that:
<pool type='zfs'>
<name>myzfspool</name>
<source>
<name>actualpoolname</name>
</source>
</pool>
The 'actualpoolname' value is a name of the pool on the system,
such as shown by 'zpool list' command. Target makes no sense
here because volumes path is always /dev/zvol/$poolname/$volname.
User has to create a pool on his own, this driver doesn't
support pool creation currently.
A volume could be used with Qemu by adding an entry like this:
<disk type='volume' device='disk'>
<driver name='qemu' type='raw'/>
<source pool='myzfspool' volume='vol5'/>
<target dev='hdc' bus='ide'/>
</disk>
There were numerous places where numatune configuration (and thus
domain config as well) was changed in different ways. On some
places this even resulted in persistent domain definition not to be
stable (it would change with daemon's restart).
In order to uniformly change how numatune config is dealt with, all
the internals are now accessible directly only in numatune_conf.c and
outside this file accessors must be used.

Rename linuxDomainInterfaceStats to virNetInterfaceStats in order
to allow adding platform specific implementations without
making consumer worrying about specific implementation to be used.
Also, rename util/virstatslinux.c to util/virstats.c so placing
other platform specific implementations into this file don't
look unexpected from the file name.
This new module holds and formats capabilities for emulator. If you
are about to create a new domain, you may want to know what is the
host or hypervisor capable of. To make sure we don't regress on the
XML, the formatting is not something left for each driver to
implement, rather there's general format function.
The domain capabilities is a lockable object (even though the locking
is not necessary yet) which uses reference counter.

Check if the buffer is in error state and report an error if it is.
This replaces the pattern:
if (virBufferError(buf)) {
virReportOOMError();
goto cleanup;
}
with:
if (virBufferCheckError(buf) < 0)
goto cleanup;
Document typical buffer usage to favor this.
Also remove the redundant FreeAndReset - if an error has
been set via virBufferSetError, the content is already freed.
Automatically allocate PCI addresses for devices instead
of hardcoding them in the driver code. The current
