65043d2dff Introduce yet another migration version in API.
Migration just seems to go from bad to worse. We already had to
introduce a second migration protocol when adding the QEMU driver,
since the one from Xen was insufficiently flexible to cope with
passing the data the QEMU driver required.

It turns out that this protocol still has some flaws that we
need to address. The current sequence is

 *  Src: DumpXML
          - Generate XML to pass to dst

 *  Dst: Prepare
          - Get ready to accept incoming VM
          - Generate optional cookie to pass to src

 *  Src: Perform
          - Start migration and wait for send completion
          - Kill off VM if successful, resume if failed

 *  Dst: Finish
          - Wait for recv completion and check status
          - Kill off VM if unsuccessful

The problems with this are:

 - Since the first step is a generic 'DumpXML' call, we can't
   add in other migration specific data. eg, we can't include
   any VM lease data from lock manager plugins
 - Since the first step is a generic 'DumpXML' call, we can't
   emit any 'migration begin' event on the source, or have
   any hook that runs right at the start of the process
 - Since there is no final step on the source, if the Finish
   method fails to receive all migration data & has to kill
   the VM, then there's no way to resume the original VM
   on the source

This patch attempts to introduce a version 3 that uses the
improved 5 step sequence

 *  Src: Begin
          - Generate XML to pass to dst
          - Generate optional cookie to pass to dst

 *  Dst: Prepare
          - Get ready to accept incoming VM
          - Generate optional cookie to pass to src

 *  Src: Perform
          - Start migration and wait for send completion
          - Generate optional cookie to pass to dst

 *  Dst: Finish
          - Wait for recv completion and check status
          - Kill off VM if failed, resume if success
          - Generate optional cookie to pass to src

 *  Src: Confirm
          - Kill off VM if success, resume if failed

The API is designed to allow both input and output cookies
in all methods where applicable. This lets us pass around
arbitrary extra driver specific data between src & dst during
migration. Combined with the extra 'Begin' method this lets
us pass lease information from source to dst at the start of
migration

Moving the killing of the source VM out of Perform and
into Confirm, means we can now recover if the dst host
can't successfully Finish receiving migration data.

The hvsupport.html.in file is forever out of date. By annotating
the driver struct tables in each driver with version information,
we can auto-generate the hvsupport.html.in file. Annotating the

68ea80cfdd maint: rename virBufferVSprintf to virBufferAsprintf
We already have virAsprintf, so picking a similar name helps for
seeing a similar purpose.  Furthermore, the prefix V before printf
generally implies 'va_list', even though this variant was '...', and
the old name got in the way of adding a new va_list version.

global rename performed with:

$ git grep -l virBufferVSprintf \
  | xargs -L1 sed -i 's/virBufferVSprintf/virBufferAsprintf/g'

then revert the changes in ChangeLog-old.

f25d064ead docs: add an IPv6 address to network XML examples
It was just pointed out that, although I added documentation for the
IPv6 additions to the network XML, I neglected to use those additions
in the examples. This patch adds an IPv6 address to each of the
examples except for the "default" network, since that is a faithful
reproduction of the default network config that's automatically
installed, which doesn't include any IPv6 address (for good reason -
because there is no such thing as IPv6 NAT, there is no one IPv6
address that would work for all installations).

4591df766d Remove the Open Nebula driver
The Open Nebula driver has been unmaintained since it was first
introduced. The only commits have been for tree-wide cleanups.
It also has a major design flaw, in that it only knows about guests
that it has created itself, which makes it of very limited use.

Discussions wrt evolution of the VMWare ESX driver, concluded that
it should limit itself to single-node ESX operation and not try to
manage the multi-node architecture of VirtualCenter. Open Nebula
is a cluster like Virtual Center, not a single node system, so
the same reasoning applies.

The DeltaCloud project includes an Open Nebula driver and is a much
better fit architecturally, since it is explicitly targetting the
distributed multihost cluster scenario.

Thus this patch deletes the libvirt Open Nebula driver with the
recommendation that people use DeltaCloud for managing it instead.

* daemon/Makefile.am, daemon/libvirtd.c, src/Makefile.am: Remove

50d8ad828d Update on the goal page
Some things to note in this patch:
   - we do extend libvirt scope beyond purely managing domains, there is
     already a number of blocks which are here as helpr functions to
     manage the resources on the host.
   - we are expanding in the direction of libvirt being sufficient to do
     most of the management on the Host (but within the limits of the need
     for virtualization, e.g. managing users on the host is out of scope)
   - we don't require anymore APIs to be supported by multiple
     hypervisors to get in, it's already the case in practice, but we
     should still make sure the semantic of those APIs are clear. We
     added quite a bit for QEmu, but for example I saw on IRC that VBox
     could emulate a network unplug/replug on a domain interface, and
     that would be a good addition even if a priori no other hypervisor
     supports it.
   - Make clear that all libvirt APIs are available remotely, which is
     key to use libvirt for building management tools.
   - link the goal page from the project main page

As for libvirt project directions, I think it just reflects the natural
evolution in the last couple of years. We are less hypervisor agnostic
and extending in the Host management. Clearly there is interest in
making sure libvirt is complete in term of features for the hypervisors
supported, especially the ones like KVM or LXC which don't really have
integrated management library.

4e3117ae50 Make LXC container startup/shutdown/I/O more robust
The current LXC I/O controller looks for HUP to detect
when a guest has quit. This isn't reliable as during
initial bootup it is possible that 'init' will close
the console and let mingetty re-open it. The shutdown
of containers was also flakey because it only killed
the libvirt I/O controller and expected container
processes to gracefully follow.

Change the I/O controller such that when it see HUP
or an I/O error, it uses kill($PID, 0) to see if the
process has really quit.

Change the container shutdown sequence to use the
virCgroupKillPainfully function to ensure every
really goes away

This change makes the use of the 'cpu', 'devices'
and 'memory' cgroups controllers compulsory with
LXC

  controllers are now mandatory

a757e60a07 domain.rng vs. formatdomain.html#elementsUSB
The Relax-NG schema for domains regarding <hostdev> doesn't match what's
implemented in src/conf/domain_conf.c#virDomainHostdevDefFormat(): The
implementation only requires @type, but the schema currently either
required none or all three attributes (@mode, @type, and @managed) to be
defined together, because they are declared in the same
<optional)-section. (@managed is currently even undocumented on
<http://libvirt.org/formatdomain.html#elementsUSB>).

Thus the following minimal <hostdev>-example fails to validate:
<domain type='test'>
        <name>N</name>
        <memory>4096</memory>
        <bootloader>/bin/false</bootloader>
        <os>
                <type arch='x86_64' machine='xenpv'>linux</type>
        </os>
        <devices>
                <hostdev type='pci'>
                        <source>
                                <address bus='0x06' slot='0x00' function='0x0'/>
                        </source>
                </hostdev>
        </devices>
</domain>

The schema is changed to match the current implementation:
1. @mode is optional (which defaults to 'subsystem')
2. @type is required
3. @managed is optional (which defaults to 'no')

The documentation is updated to mention @managed.

6e9f3dfa0c build: Fix API docs generation in VPATH build
XSLT allows for two ways of generating the output of transformation.
Either implicit, which xsltproc prints to stdout and can be redirected
to a file using -o file. Or explicit, which means the stylesheet
contains <xsl:document> element which specifies where the output should
be saved. This can be used for generating more files by a single run of
xsltproc and -o directory/ can change the directory where the output
files will be stored.

devhelp.xsl is special in that it combines both options in one
stylesheet, which doesn't work well with -o:

xsltproc --nonet -o ./devhelp/ ./devhelp/devhelp.xsl ./libvirt-api.xml

Outputs 4 *.html files into ./devhelp but then tries to write to
./devhelp/ as a file (hence the I/O error) rather than writing output to
the fifth file devhelp/libvirt.devhelp.

This patch modifies devhelp.xsl so that all files are generated using
<xsl:document> element and -o directory/ can be used to override output
directory where those files are saved.
