Introduce vbox_uniformed_api to deal with version conflicts. Use
vbox_install_api to register the currect vboxUniformedAPI with
vbox version.
vboxConnectOpen has been rewritten.
Martin Kletzander pointed out in email that my commit 2a193f64
introduced a crash in networkCreateInterfacePool() during startup of
any network that doesn't have a <pf> subelement of its <forward>
element. He also supplied a patch.
http://www.redhat.com/archives/libvir-list/2014-August/msg00655.html
I expanded on that patch by cleaning up now-extraneous checks in the
callers of networkCreateInterfacePool().
Fortunately the offending patch hasn't been in any release, and hasn't
been (to my knowledge) backported to any other branch.

Otherwise devpts will use an unmapped gid and openpty()

During a QEMU live migration several warning messages about job
handling could be written to syslog on the destination host:
"entering monitor without asking for a nested job is dangerous"
The messages are written because the job handling during migration
uses hard coded asyncJob values in several places that are incorrect.
This patch passes the required asyncJob value around and prevents
the warnings as well as any issues that the warnings may be referring
to.

Perl is necessary to our build processing, it will invoke a lot of
generating script, like: gendispatch.pl. If perl is missing, it's
ok for build from git checkout, because autogen.sh will tell you.
But for compiling from a release tarball, configure will just record
a missing message, and continue, then build failed, like:
https://www.redhat.com/archives/libvirt-users/2014-August/msg00050.html
So need to enhance configure script to handle this negative case.

This patch changes the setmaxmem function to support the '--live',
'--config', and '--current' flags by revectoring the code through
the setmem function using the VIR_DOMAIN_MEM_MAXIMUM flag. The
setmem code is refactored to handle both cases depending on the flag.
The changed maxmem code for the MEM_MAXIMUM path will not allow
modification to the memory values of an active guest unless the --config
switch is used.

Libvirt is really chatty when the DEBUG log level is enabled. When a
host uses journald we'd enable debug logging to journald when only
specifying the debug log level. As journald may employ rate throttling
this would lock up the daemon until it's able to flush all debug
messages.
This patch changes the default log level to VIR_LOG_INFO when using the
default (unconfigured) log output to journald.
To still allow debug logging to journald the user now has to explicitly
specify journald as a log output with priority 1 in the "log_outputs"
configuration option. This patch also changes the config file template
to be explicit about this change and notify the user about the possible
consequence of debug logging into journald.

At the beginning of the qemu config file parsing function there
are 3 helper macros defined: GET_VALUE_BOOL, GET_VALUE_LONG and
GET_VALUE_STR. Later, when they are no longer needed they are
undefined in order to keep the namespace clean. However, the
GET_VALUE_STRING is undefined instead of GET_VALUE_STR.

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>
In qemuMigrationToFile we enter the monitor multiple times and don't
check if the VM is still alive after returning form the monitor. Add the
checks to skip pieces of code in case the VM crashes while saving it's
state.
Saving a shutoff VM doesn't make sense and libvirtd crashes while
attempting to do that. Check that the domain is alive after entering
the save async job.

There's this <driver/> element under <interface/> which can have
several attributes. However, the driver element is currently formated
only if the driver's name or txmode has been specified. This makes
only a little sense as we parse even partial <driver/>, for instance:
<interface type='user'>
<mac address='52:54:00:e5:48:58'/>
<model type='virtio'/>
<driver ioeventfd='on' event_idx='on' queues='5'/>
</interface>
But such XML would never get formatted back.

When a network is defined with "<pf dev='xyz'/>", libvirt will query
sysfs to learn the list of all virtual functions (VF) associated with
that Physical Function (PF) then populate the network's interface pool
accordingly. This action was previously done only when the first guest
actually requested an interface from the network. This patch changes
it to populate the pool immediately when the network is started. This
way any problems with the PF or its VFs will become apparent sooner.
Note that we can't remove the old calls to networkCreateInterfacePool
that happen whenever a guest requests an interface - doing so would be
asking for failures on hosts that had libvirt upgraded with a network
that had been started but not yet used.
This resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1047818
networkCreateInterfacePool was a bit loose in its error cleanup, which
could result in a network definition with interfaces in the pool that
were NULL. This would in turn lead to a libvirtd crash when a guest
tried to attach an interface using the network with that pool.
In particular this would happen when creating a pool to be used for
macvtap connections. macvtap needs the netdev name of the virtual
function in order to use it, and each VF only has a netdev name if it
is currently bound to a network driver. If one of the VFs of a PF
happened to be bound to the pci-stub or vfio-pci driver (indicating
it's already in use for PCI passthrough), or no driver at all, it
would have no name. In this case networkCreateInterfacePool would
return an error, but would leave the netdef->forward.nifs set to the
total number of VFs in the PF. The interface attach that triggered
calling of networkCreateInterfacePool (it uses a "lazy fill" strategy)
would simply fail, but the very next attempt to attach an interface
using the same network pool would result in a crash.
This patch refactors networkCreateInterfacePool to bring it more in
line with current coding practices (label name, use of a switch with
no default case) as well as providing the following two changes to
behavior:
1) If a VF with no netdev name is encountered, just log a warning and
continue; only fail if exactly 0 devices are found to put in the pool.
2) If the function fails, clean up any partial interface pool and set
netdef->forward.nifs to 0.
